Isover mineral wool slabs. Izover insulation - technical characteristics. Subtleties of working with ISOVER insulation

The building materials market is replete with a variety of insulation and soundproofing materials for buildings. As a rule, the main difference between them is the form of manufacture and the composition of the base, but the country of manufacture, the reputation of the manufacturer and the possibilities of application also play a significant role.

Insulation materials usually cost significant sums, so in order not to go to waste, you need to rely on a guaranteed quality product, for example, products from Isover. According to experts and customer reviews, it occupies a leading position in such characteristics as service life, reliability and efficiency.

Peculiarities

Isover insulation is used both in residential buildings, as well as in public institutions and industrial buildings. The production and sale of this product is carried out by a company that is part of the international association Saint Gobain– one of the leaders in the building materials market, which emerged more than 350 years ago. Saint Gobain is known for its innovative developments, the use of modern technologies and the high quality of its products. All of the above points also apply to Isover insulation, produced in different modifications.

Isover products share many of the pros and cons of mineral wool as they exhibit similar properties. They are sold on the market in the format of slabs, rigid and semi-rigid, and mats, rolled into rolls using our own technologies patented in 1981 and 1957. This insulation is used to treat roofs, ceilings, facades, ceilings, floors and walls, as well as ventilation pipes. Isover is based on glass fibers. Their length is from 100 to 150 microns, and their thickness is from 4 to 5 microns. This material is elastic and resistant to stress.

Isover insulation is tensile strength, which means that it can be placed on a structure complex shape. For example, these include pipes, elements of production lines, industrial equipment and others.

When using Isover as insulation or sound insulator, it must be protected from moisture.

Typically, vapor barrier and waterproofing films are used for this. It is customary to install a vapor barrier from the inside of the house to protect it from condensation. The waterproofing film is placed outside, protecting from rain and melting snow. As a rule, Isover is installed without the use of fasteners, the only exception being insulation of the ceiling - in this case, dowels are used.

Under the brand's umbrella, a lot of insulation materials are produced that have different purposes and perform different functions. They are divided into two groups: for industrial and domestic use. In private housing construction, the material most often used is “Classic”, marked with the letter “K”.

The price of Isover insulation may vary in different regions of our country. Typically, the average varies from 120 to 160 rubles per square meter. In some areas it is more profitable to purchase it in packages, and in others - in cubic meters.

Subtleties of manufacturing

Saint Gobain has been operating on the Russian market for more than 20 years and produces materials at two factories: in Yegoryevsk and Chelyabinsk. All enterprises undertake to undergo certification of the international environmental management standard, which makes Isover insulation an environmentally friendly product, with its environmental characteristics on a par with cotton and flax.

Different types of Isover contain both glass and basalt fibers. This structure is the result of processing broken glass, quartz sand or mineral rocks of the basalt group.

• It is in Isover that mineral raw materials are used. Its components are melted and drawn into fibers, following TEL technology. The result is very thin threads that are connected to each other using a special resin composition.

• The composition of cullet, limestone, quartz sand and other minerals is first thoroughly mixed.
• To obtain a homogeneous fluid mass, the resulting mixture must be melted at a temperature of 1300 degrees.
• Afterwards, the “liquid glass” falls onto a rapidly moving bowl, in the walls of which there are holes. Thanks to physics, the mass flows out in the form of threads.
• At the next stage, the fibers must be mixed with polymer glue, which has a yellow tint. The resulting substance enters the oven, where it is blown with hot air and moved between steel shafts.
• The glue sets, the layer is leveled and glass wool is formed. All that remains is to send it under the circular saws to cut it into fragments of the required size.

When purchasing Isover, you can view quality certificates. When the material is produced under license, the seller provides documents confirming the standards EN 13162 and ISO 9001. They become a guarantee that Isover is made of safe materials and there is no ban on its use indoors.

Varieties

There are different types of insulation depending on whether they are sold in roll format or in slabs. Both varieties can have different sizes, different thicknesses, and different laying technologies.

Insulation materials are also divided depending on the industry of application. They can be universal or suitable for specific areas - walls, roofs or saunas. Often the purpose of insulation is encrypted in its name. In addition, it is worth adding that materials are divided into those used indoors and on the facades of buildings.

It is also worth adding that Isover are divided according to the hardness of the material. This parameter, related to the characteristics of GOST, is indicated on the packaging and is closely related to the density, degree of compression in the packaging and thermal insulation properties.

Advantages and disadvantages

All Isover insulation products have similar positive and negative characteristics. If we talk about the advantages, we highlight the following:

• The material has low thermal conductivity. This means that the heat “lingers” in the room for a long time, so it is possible to spend less on heating, thereby saving significant amounts.
• The insulation demonstrates a high ability to absorb noise due to the presence of an air gap between the fibers, which absorbs vibrations. The room becomes as quiet as possible, protected from external noise.
• Isover has a high level of vapor permeability, that is, the material breathes. It does not retain moisture and the walls do not begin to become damp. In addition, the dryness of the material increases its service life, because the presence of moisture negatively affects thermal conductivity.

• Thermal insulators are completely non-flammable. On the flammability scale they received the highest rating, that is, the best resistance to fire. As a result, Isover can be used to construct wooden buildings.
• Plates and mats are lightweight and can be used in buildings that cannot bear excessive load.
• The service life can reach 50 years.
• The insulation materials are treated with compounds that increase moisture resistance.
• The material is easy to transport and store. The manufacturer compresses Isover 5-6 times during packaging, and then it completely returns to its shape.
• There are product lines with different technical characteristics designed for different areas of construction.

• Isover is highly elastic. The insulation is superior to other mineral wool in this indicator thanks to the special TEL technology used to produce it.
• 5 centimeters of mineral wool are equal in thermal conductivity to 1 meter of brickwork.
• Isover is resistant to biological and chemical influences.
• Isover is quite affordable, especially when compared to other alternatives.
• The material demonstrates high density and rigidity, which allows it to be installed without additional fasteners.

However, there are still several disadvantages:

• A relatively complex installation process, during which it is necessary to additionally protect the respiratory system and eyes.
• The need to lay an additional layer of waterproofing during construction. Otherwise, it will absorb moisture, which will disrupt the thermal insulation characteristics. In winter, mineral wool can even freeze, which is why it is so important to leave a ventilation gap.
• Some types are still not non-flammable, but self-extinguishing - in this case, you will additionally have to comply with fire safety requirements.
• The soft structure of wool limits the scope of application.
• The only negative for industrial enterprises is that when the temperature rises to 260 degrees, Isover loses its properties. Namely, there such a temperature is quite possible.

Specifications

Isover is produced using a special patented TEL technology and has excellent technical characteristics.

• Coefficient of thermal conductivity very small - only 0.041 watts per meter/Kelvin. A big plus is the fact that its value does not increase over time. The insulation retains heat and traps air.
• Regarding sound insulation, the indicators differ for different models, but are always on high level. This means that any type of Isover will somehow protect the room from external noise. All this is ensured thanks to the air gap between the glass fibers.
• Regarding flammability, then the Isover varieties are either non-flammable or low-flammable and self-extinguishing. This value is determined by the relevant GOST and means that the use of almost any Isover is absolutely safe.
• Vapor tightness of this insulation ranges from 0.50 to 0.55 mg/mchPa. If the insulation is moistened by at least 1%, the thermal insulation will immediately deteriorate by as much as 10%. To prevent this from happening, it is necessary to leave a gap of at least 2 centimeters between the wall and the insulation for ventilation. Glass fibers will return moisture and thereby maintain thermal insulation.

• Isover can serve up to 50 years and not lose its thermal insulation qualities for quite an impressive period.
• In addition, the insulation contains components with water-repellent properties, which makes it inaccessible to mold.
• It is also important that in fiberglass material bugs won't be able to settle in and other pests. Additionally, Isover has a density of approximately 13 kilograms per cubic meter.
• Isover considered environmentally friendly insulation and absolutely safe for human health.
• It is much lighter than competitors, therefore can be used in rooms made of fragile materials or in which the creation of excessive load is prohibited. The thickness of a single-layer Isover can be either 5 or 10 centimeters, while for a two-layer Isover each layer is limited to 5 centimeters. Slabs are usually cut meter by meter, but there are exceptions. The area of ​​one roll varies from 16 to 20 square meters. Its standard width is 1.2 meters, and its length can range from 7 to 14 meters.

The Isover company produces not only universal insulation materials, but also highly targeted ones that are responsible for specific building elements. They differ in size, functions and technical properties.

Isover can be produced for light thermal insulation (wall and roof insulation), general building insulation (soft slabs for frame structures, medium-hard slabs, mats without fasteners and mats with foil on one side) and special purposes (for pitched roofs).

Isover has a special marking where:

• KL are slabs;
• KT – mats;
• OL-E – mats of special rigidity.

The numbers demonstrate the thermal conductivity class.

The packaging also indicates where this or that type of insulation can be used.

• "Isover Optimal" It is considered a universal material that is used for processing floors, walls, partitions, roofing and floors along joists - that is, all parts of the house except the foundation. The material has low thermal conductivity and retains heat in the house, it is elastic and non-flammable. Installation is very easy, does not require additional fasteners, and, given its versatility, all of the above points make “Optimal” one of the most popular representatives of Isover.
• "Isover Pro" is also a universal insulation material. It is sold in the form of mats, rolled into rolls, and is used for roofs, walls, ceilings, ceilings and partitions. “Profi” has one of the lowest thermal conductivities and is very convenient to cut. The insulation can be 50, 100 and 150 mm thick. Just like “Optimal”, “Profi” belongs to the NG class in terms of flammability - that is, it is absolutely safe in a fire situation.

• "Isover Classic" is chosen for thermal and sound insulation of almost all parts of the house, except those that bear the greatest load. “Exceptions” include the basement and foundation. The material is sold both in rolls and slabs and has low rigidity. Its porous structure makes it an excellent insulator. However this type does not differ in strength and durability, which means it is not suitable for installation under screed and for finishing walls under plaster. If you still want to use it to insulate the facade, then only in combination with siding, lining or facade panels fixed to the sheathing. “Classic” insulates the house very well and allows you to reduce heating costs by almost half. In addition, it is a good sound insulator and protects the building from unnecessary noise.

• "Isover Warm House-Stove" and "Isover Warm House" used in the installation of most parts of the house. They have almost the same specifications excluding volume and linear dimensions. However, it is customary to use slabs in one area and mats in another. “Warm House-Slab” is selected for insulating vertical surfaces, inside and outside the house, as well as frame buildings. “Warm House”, sold in the form of rolls of mats, is used to insulate interfloor ceilings and the floor above the basement (installation takes place between the joists).
• "Isover Extra" manufactured in the form of plates with increased elasticity and a 3D effect. The latter means that after compression the material expands and occupies all the free space between the surfaces requiring insulation. The plates are tightly connected to each other and also fit tightly to the surfaces. “Extra” is also universal, but is usually used for insulating walls indoors. It is worth adding that it can also be used for thermal insulation of facades in the case of subsequent cladding with brick, lining, siding or panels, and for roofs. "Isover Extra" is considered one of the most effective materials for heat preservation.

• "Isover P-34" Available in the form of slabs, the thickness of which can be 5 or 10 centimeters. They are mounted on a frame and used to insulate the ventilated parts of the house - the facade or multi-layer masonry. You can insulate vertical, horizontal, and inclined surfaces, since the model is very elastic. “P-34” is easily restored after deformation and is resistant to shrinkage. It is completely non-flammable material.
• "Isover Frame P-37" used for insulation of floors between floors, roof slopes and walls. It is important to consider that the material must adhere tightly to the surface. “Isover KT37” also adheres tightly to the surface and is used for insulating floors, partitions, attics and roofs.

• "Isover KT40" refers to two-layer materials and is sold in the form of rolls. It is used exclusively on surfaces located horizontally, that is, for ceilings and floors. If the cavity depth is insufficient, the material is divided into two separate layers of 5 centimeters each. The material has high vapor permeability and refers to non-combustible materials. Unfortunately, it cannot be used on surfaces with difficult wet conditions.
• "Isover Styrofoam 300A" requires mandatory fastening and is produced in the form of slabs. The material has increased moisture resistance and thermal insulation due to the presence of extruded polystyrene foam in the composition. This insulation is used to treat walls inside and outside the room, floors and flat roofs. It is possible to apply plaster on top.

• "Isover Ventiterm" has a somewhat unusual scope of application. It is used for ventilated facades, pipes, plumbing, and also to protect precision instruments from the cold. You can work with it both with and without fasteners. This insulation is produced in the form of slabs. Its technical characteristics are quite serious, especially in terms of strength - an order of magnitude better than that of ordinary mineral wool.
• "Isover Frame House" used for insulating walls from the outside and inside, pitched roofs and attics, as well as ceilings and partitions. Overall, it is suitable for improving any frame structures in the house. The elasticity of the material helps maintain its shape during operation and installation, and stone wool fibers provide additional protection from noise.

Roofing

For roof insulation, some universal varieties of Isover are used, for example, "Optimal" and "Profi", as well as highly specialized - “Isover Warm roof” and “Isover Pitched roofs and attics”. Both materials are intended for the same purpose, but have different characteristics: they differ in release form, linear dimensions and material used. They also undergo special processing, which gives the products increased moisture resistance.

• "Warm Roof" produced in the form of mats rolled into rolls. They are sold in plastic packaging with markings that allow the material to be cut according to its width. “Pitched roofs” are sold in the form of slabs, compressed and packaged in polyethylene. They are used in the case of insulation of pitched and attic roofs, as well as for surfaces inside and outside the building.

• "Isover Pitched Roof" used exclusively for roof insulation. It is moisture resistant, does not allow sound to pass through, has high vapor permeability and is not flammable. As a rule, it is recommended to use it in two layers, with the top covering the joints of the bottom - this way the material will retain heat even better. “Pitched Roof” is produced in the form of slabs with a width of 61 centimeters and a thickness of 5 or 10 centimeters. “Pitched Roof” is highly hydrophobic - it does not absorb moisture, even if immersed in water for a long time. This allows the material to be used in difficult conditions, not suitable for other insulation materials.
• "Isover Ruf N" is an insulation material for flat roofs. It has the maximum level of thermal protection and is compatible with any building materials.

• "Isover Master of Warm Roofs" also has a high thermal protection rate. Due to its vapor permeability, it eliminates the accumulation of moisture in the wall. In addition, when insulated from the outside, the slab will retain its properties in any weather.
• "Isover OL-P" is a special solution for flat roofs. It has ventilated grooves to remove moisture and is created using tongue-and-groove technology, which increases the tightness of the mineral wool layer.

Facades for plaster

To insulate the facade for the purpose of further coating with plaster, the following varieties of Isover are used: “Facade-Master”, “Plaster Facade”, “Facade” and “Facade-Light”. All of them are sold in the form of slabs and are non-flammable material.

• "Facade-Master" p used for insulating facades of residential buildings up to 16 meters high. The plaster must be applied thin layer.
• "Plaster Facade", which is an innovative material, costs much less than the previous one, but performs the same functions and is applied under the same conditions.
• "Facade" used for subsequent coating with decorative plaster.
• "Facade-Light" used for houses with a small number of floors and for subsequent finishing with a thin layer of plaster. For example, this option is chosen by owners country houses. This material is durable, rigid, but light in weight.

For soundproofing buildings

In order to protect the house from various noises, both external and internal, “Isover Quiet House” and “Isover Sound Protection” are used. Besides, You can also use universal insulation materials – “Classic” and “Profi”.

• "Quiet House" has a high ability to absorb noise, so it is often chosen for soundproofing walls and partitions between rooms. The slabs are also used for horizontal surfaces - for joists, beams, spaces between suspended ceiling and original. The material performs two functions, so the home becomes quiet and warm.
• "Sound Protection" has high elasticity, therefore it is often mounted inside a frame sheathing, which acts as a partition or is fixed to the wall (in the case of facade coverings). The material can be used in combination with other insulation materials and thereby create a double layer - retaining heat and preventing sound. This solution will be especially effective for creating frame partitions and attic floors.

Insulation of walls inside

For thermal insulation and sound insulation of building walls inside and outside, “Isover Profi”, “Isover Classic Plate”, “Isover Warm Walls”, “Isover Warm and Quiet Wall” and “Isover Standard” are recommended. These insulation materials are sold both in mats in rolls and in the form of sawn sheets.

• "Standard" usually chosen for insulating structures consisting of many layers. In this case, siding, lining, brick, block house and other materials can be used as finishing. In addition, these slabs are suitable for thermal insulation of frame structures, for attic and pitched roofs. Due to its average density, the material is not suitable for further plastering of walls. “Standard” has good elasticity, which means a tight fit to surfaces and structures. The plates are fixed using special clamping fasteners.

• "Warm walls"- these are plates that are also made of glass fibers, but in addition they are reinforced with water-repellent treatment. This variety is also used for thermal and sound insulation of walls inside and outside, installation in a frame, insulation of roofs, loggias and balconies. Increased moisture resistance becomes an additional plus in the last two examples. The material is elastic and elastic, does not slip or break.
• "Warm and Quiet Wall" It is sold both in the form of slabs and rolls. The material has a porous structure, which allows it to perform two functions. In addition, this variety is characterized by increased vapor permeability and, as it were, “breathes”. This allows you to create a comfortable environment in living spaces. The plates are elastic and do not even need to be additionally fixed - they themselves will “crawl” qualitatively inside the frame.

• "Warm and Quiet Wall Plus" has similar characteristics to the “Warm and Quiet Wall”, which will be discussed a little later, but has lower thermal conductivity and better sound insulation. The slabs are used for walls inside the building, walls outside under siding or facade coverings and, if available additional protection, for insulation of frame structures.

Thermal insulation of the floor

To insulate floors with high quality, you can choose two specialized materials - “Isover Floor” and “Isover Floating Floor”, which have slightly different technical and operational characteristics, which, however, combine damping properties and mechanical characteristics. Both types are easy to install, but using different technologies. In addition to insulation, these materials are also distinguished by high-quality double-sided sound insulation.

• "Flor" used for the construction of floating floors and joist structures. In the first case, the material covers the entire surface and creates a warm and quiet floor. Thanks to the availability of adaptation to high loads insulation can also be placed under a concrete screed.

• "Floating floor" is always used to create a concrete screed that will not be connected to the walls and base, in other words, for a “floating” floor. The slabs are always laid out on a perfectly flat surface and connected using a technique called “tenon and groove”. Due to the fact that the fibers are arranged vertically, this type of insulation demonstrates outstanding strength characteristics.

Thermal insulation of baths

To insulate baths and saunas, Isover has special solutions - mats rolled into a roll and called “Isover Sauna”. This coating has a foil layer with outside, which reflects heat and creates a vapor barrier.

"Sauna" consists of two layers. The first is fiberglass-based mineral wool, and the second is foil. It is worth noting that mineral wool is a non-flammable material, and the foil coating has a G1 flammability class. It can withstand temperatures up to 100 degrees due to the presence of glue, and at higher temperatures it can ignite and go out on its own. To avoid accidents, the foil layer is additionally covered with clapboard.

“Isover Sauna”, on the one hand, performs the functions of thermal insulation, and on the other hand, it acts as a barrier to steam, so that the mineral layer is not damaged by a large amount of evaporation. Foil reflects heat from the walls in the room and increases the level of heat retention.

Installation nuances

First of all, you need to choose correct view Isover, for this it will be enough just to look at the existing markings. Each product is assigned a grade and number of stars, and this data is contained on the packaging. The more stars, the better the heat-shielding properties of the material.

To insulate a house without special requirements, two stars are enough; for increased thermal protection and ease of installation, three stars are selected. Four stars are assigned to the latest generation product with increased thermal protection. In addition, each package has a label with precise data regarding thickness, length, width, package volume and number of pieces.

Mineral wool insulation is installed in the same way as any other thermal insulation material. When insulating walls indoors, the first step is to make a sheathing of wooden or metal strips. Drywall will be attached to them later. The walls are first primed, and on those that border the street, a heat-reflecting coating is fixed.

When installing the sheathing, it is necessary to observe a step corresponding to the width of the Isover, slabs or mats. The next step is to glue the insulation sheets to the wall, if necessary, attach a water-repellent film and fill the horizontal strips.

Insulating walls outside a building begins with attaching a wooden frame to the wall.

• It is usually made from bars measuring 50 by 50 millimeters, which are attached vertically.
• The insulation can be installed in either one or two layers. It is placed in the structure so that it fits tightly to the wall and frame without gaps or cracks.
• Next, the bars are again attached on top, but horizontally. The distance between the horizontal bars should be the same as between the vertical ones.
• With two-layer insulation, a second layer of thermal insulation is placed in the horizontal sheathing, overlapping the joints of the first.
• To protect against moisture, a hydro-windproof membrane is placed outside, the necessary ventilated gap is created, and after that you can begin cladding.

Insulation of the roof begins with the fact that a hydro-windproof membrane, which is also produced by Isover, is stretched along the upper edge of the rafters.

• It is fastened with a construction stapler, and the joints are glued with reinforced mounting tape.
• Next, it is recommended to begin the installation of the roofing covering - a gap is formed on top of the membrane using a pressure bar, and then the covering is installed on a counter-lattice made of 50 by 50 millimeter bars.
• The next step is to install the heat insulator directly. With a standard distance between the rafters, the insulation will need to be cut into 2 halves and each installed in the frame. Most often, in one piece it is possible to insulate the entire length of the roof slope. If the distance between the rafters is non-standard, then the dimensions of the thermal insulation slabs are determined independently. We must not forget that their width should be at least 1-2 centimeters larger. Thermal insulation should fill the entire space without gaps or cracks.
• Next, a vapor barrier membrane is installed along the lower plane of the rafters, which will protect against moisture inside the room. The joints are glued vapor barrier tape or reinforced construction tape. As always, a gap is left and the installation of the internal cladding begins, which is attached to the sheathing using nails or self-tapping screws.

Floor insulation along joists is selected in two cases: attic floors and floors above basements with no heating.

• First, logs are installed and covered with roofing felt to prevent rotting and destruction of the structure.
• Then the heat insulation material is installed inside. For cutting, a knife with a blade length of more than 15 centimeters is used. The roll is simply rolled out between the joists to cover the entire space, and no additional fixing actions are required. During installation, avoid wetting the material.
• The next step is to install an overlapping vapor barrier membrane; the joints are taped as usual with reinforced mounting tape or vapor barrier tape. A base is installed on top of the vapor barrier, which is attached to the joists with screws.
• Everything is completed with finishing: tiles, linoleum, laminate or carpet.

When carrying out events for the purpose of soundproofing partitions The first step is to mark and assemble the guides and their further installation.

• Separately standing partition It is necessary to line one side with plasterboard, and you can begin to create sound insulation.
• Isover is mounted between the posts of a metal frame without fasteners, fitting tightly to the structure and filling the entire space without cracks or gaps.
• Then the partition is sewn up on the other side with plasterboard, and the seams are puttied using paper reinforcing tape.

Thermal insulation of baths and saunas starts with creation wooden frame from bars measuring 50 by 50 millimeters.

• The bars are attached horizontally.
• The insulation is cut into two halves with a knife and installed in the frame, with the foil layer facing the inside of the warm room. As usual, the material is installed without gaps or cracks.
• The joints are well sealed with foil tape, as is the outer surface of the sheathing. All this will create a sealed vapor barrier circuit.
• Sheathing is placed on top of the horizontal bars to create an air gap. It will speed up heating and increase the service life of the casing.
• At the final stage, the internal lining is installed.

One of the main mistakes when using Isover is the wrong choice of material width.

If a roll of insulation lies loosely between, for example, beams, then the main goal will not be achieved. It will be quite expensive to cut it into several rows, and leaving it in this state, despite the cracks and gaps, is completely pointless. Therefore, it is extremely important to calculate all the necessary dimensions for work surface taking into account the length, depth and width of the beams or sheathing.

In the case when the insulation is in direct contact with wires or pipelines, it is necessary to check the tightness of communications. In terms of electricity, the situation is not very dangerous, but in the second case it is better to isolate communications using a corrugated pipe.

In addition, all materials must be completely dry before the insulation process begins. If the surface for which Isover is intended is wet, then you will either have to wait for it to dry, or dry the room with a hairdryer or gun.

But most terrible mistake, of course, there will be a lack of waterproofing and vapor barrier. If you miss these points, the material will be wasted, and the thermal insulation effect will not be achieved.

How to calculate: instructions

It is very important to be able to correctly calculate the required thickness of insulation to create and maintain comfortable temperature in room. To determine it, it is necessary to reproduce the thermal engineering algorithm, which exists in two versions: simplified for private developers, and more complex for other situations.

The most important quantity is heat transfer resistance. This parameter is denoted as R and is defined in m2×C/W. The higher this value, the higher the thermal insulation of the structure. Experts have already calculated the recommended average values ​​for various regions of the country with different climatic characteristics. When building and insulating a house, it is necessary to take into account that the heat transfer resistance must be no less than the normalized one. All indicators are indicated in SNiP.

When building and insulating a house, it is necessary to take into account that the heat transfer resistance must be no less than the normalized one. All indicators are indicated in SNiP.

There is also a formula that shows the relationship between the thermal conductivity of a material, the thickness of its layer and the resulting thermal resistance. It looks like this: R = h/λ. R is the heat transfer resistance, where h is the thickness of the layer, and λ is the thermal conductivity coefficient of the layer material. Thus, if you find out the thickness of the wall and the material from which it is made, you can calculate its thermal resistance.

If there are several layers, the resulting numbers will have to be summed. Then the resulting value is compared with those normalized by region. This turns out to be the difference that the thermal insulation material will have to cover. Knowing the thermal conductivity coefficient of the material chosen for insulation, it is possible to determine the required thickness.

It is worth remembering that in this algorithm there is no need to take into account layers that are separated from the structure by a ventilated opening, for example, a certain type of facade or roof.

This happens because they do not affect the overall heat transfer resistance. In this case, the value of this “excluded” layer is zero.

It must be remembered that the material in the roll is cut into two equal parts, usually 50 millimeters thick. Thus, having identified the required thickness of the insulation squares, the product should be laid in 2-4 layers.

• To calculate required amount standard packaging for roof insulation, you will have to multiply the area of ​​the insulated roof by the planned thickness of the thermal insulation and divide by the volume of one package - 0.661 cubic meters.
• To calculate the number of packages you will have to use for facade insulation for siding or lining, the area of ​​the walls must be multiplied by the thickness of the thermal insulation and divided by the volume of the package, which can be equal to 0.661 or 0.714 cubic meters.
• To determine the number of Isover packs required for floor insulation, the floor area is multiplied by the thickness of the thermal insulation and divided by the volume of one package - 0.854 cubic meters.

Safety precautions

When working with fiberglass insulation, it is necessary to use safety glasses, gloves and a gauze bandage or a respirator. Clothes should have long sleeves and long legs, and don’t forget about socks. It’s better, of course, to play it safe and wear protective overalls. Otherwise, installers are expected unpleasant consequences– itching and burning throughout the body. By the way, this requirement applies to all types of work with any mineral wool.

To protect the residents of the house from glass dust, it is recommended to put a special film between the insulation and the top layer, for example, clapboard.

Even if he gets hurt wood panel, insulation particles will not be able to penetrate into the room. You can cut the material using a simple knife, but it must be sharpened as sharply as possible; in extreme cases, you can use a fairly sharp chisel.

Insulation must always be stored in a dry closed place, and the packaging must be opened only at the installation site. The room should be well ventilated, and after completion of work, all waste should be collected and thrown away. Also, after completing the installation, you need to take a shower or at least wash your hands.

Eco-friendly, efficient, durable, for all types of structures - these are the insulation materials produced by the Isover company in recognizable yellow packaging. Like the price range, the range of its insulating materials is quite wide. Under the Isover brand they produce insulation based on quartz and basalt, for various types facades, ceilings, roofs, partitions. The right product can be found for both private housing construction and serial construction.

What are Izover insulation materials?

Izover thermal insulation is high-quality mineral wool insulation with a low thermal conductivity coefficient and a service life of at least 50 years.

Please note: depending on the brand of insulation, the thermal conductivity coefficient ranges from 0.035-0.042 W/(m K).

Their special structure allows not only to retain heat in rooms, but also effectively reduce the noise level in them.

The materials are produced in the form of slabs geometric shape and rolled mats. This makes it easier to work on certain areas of the structure. Most roll insulation is designed to insulate roofs and horizontal surfaces. They are convenient to roll out large area . The slab material is suitable for working with frame structures and walls.

All Izover insulation materials are non-flammable, which is confirmed by fire tests. Made from environmentally friendly raw materials, they do not emit harmful substances into the atmosphere, do not have a negative impact on human health.

Mineral wool insulation based on quartz

Quartz-based mineral wool is an environmentally friendly product that also contains limestone and soda. Isover quartz insulation is available in a wide range. How is that universal solutions for any walls and ceilings, and special-purpose thermal insulation - for roofing, frame structures and others.

All Izover roof insulation materials have low water absorption, good compressive strength (25-60 kPa), and low weight. Their thermal conductivity coefficient is 0.037 W/(m K).

Mineral wool for insulation of frame structures

For thermal insulation of frame structures, Isover has released a special line of mineral wool - Isover Frame. Each name is marked with letters and numbers. The letters (“P” and “M”) stand for “slab” and “mat,” respectively. But the numbers are the thermal conductivity coefficient of the material. As a result, in stores you can find Isover Frame P-32, P-34, P-37, as well as Isover Frame M-34, M-37, M-40.

This line of insulation is perfect for serial buildings and objects with increased energy saving requirements. When using them Savings on heating costs can be 13-25%.

The thickness of Izover Frame slabs and mats varies widely (50, 60, 65, 70, 100 mm). Like the width, it can be customized.

Izover for ventilated and plaster facades

Izover insulation for facades can be divided into a separate line, since it includes many items.

Solutions for plaster facades:

• Isover Plaster Facade. Available in thicknesses of 50, 100, 150 mm. Suitable as a base for a thin layer of plaster.
• Isover Facade Light. 1.5 times lighter than mineral wool with the same strength index. Used in as a base for a thin layer of plaster.
• Isover OL-E. This mineral wool is used under a thick layer of plaster.

For ventilated facades, the Isover VentFacade line is presented. Depending on the purpose, these insulation materials have additional markings:

• “Top” – for the top layer of two-layer thermal insulation.
• “Niz Light” – lightweight slabs for the bottom layer of thermal insulation.
• “Bottom” is the bottom layer of two-layer insulation.
• “Mono” is a solution for thermal insulation in one layer.
• “Optima” is the most heat-saving option for single-layer insulation.

All mineral wool for facades is characterized light weight, increased strength and low water absorption.

Basalt insulation Isover

Izover insulation materials of this group are made from natural raw materials of volcanic origin. It belongs to the basalt group, which determined the name of mineral wool thermal insulation. Isover basalt insulation is not presented in such a wide range as quartz. But even among them, materials are distinguished by purpose and type of construction.

Mineral wool for walls and frame structures

Basalt mineral wool has improved strength characteristics, vapor permeability and resistance to the negative effects of moisture.

For frame structures, external and internal walls, Izover offers:

• Izover Frame House. Universal insulation for any frame structures both in the house and in the apartment.
• Isover Master of Warm Walls.
• Isover Optimal. Universal insulation for walls, roofs, interfloor ceilings, floors along joists, partitions. Elastic, holds its shape well and does not require the use of additional fasteners.
• Isover Light. This is mineral wool for partitions, frame structures, suspended ceilings. Provides additional sound insulation and is characterized by increased elasticity.
• Isover Flor. At the same time serves as heat and sound insulation of floors, reducing the impact noise level to 35 dB.

The standard thickness of these insulation materials is 50 or 100 mm. And only Izover Floor has 25 mm.

Basalt thermal insulation for facades

Due to their properties, Izover basalt insulation materials are ideal for insulating ventilated facades and facades under plaster, siding, and brick. Thus, Isover FACADE-MASTER is designed for insulating external walls under a thin-layer plaster facade. Features high adhesion.

Isover Facade are slabs with high mechanical strength and uniform structure. The thickness of the slab can reach 200 mm. Isover Standard is used for insulating external walls under brick and siding. It is characterized by high elasticity and chemical resistance to elements of the insulated structure. Isover Venti and Isover Venti Optimal are suitable for ventilated facades.

Basalt mineral wool for roofing

Izover produces insulation for both pitched and flat roofs.

For a pitched roof, you can use one of the universal insulation options or a special one - Isover Master of Warm Roofs. Plates of this material allow minimize heat loss in the cold season and keep rooms cool in summer.

For insulating flat roofs, Isover has the Isover Roof series. These are slabs various sizes, which are compatible with most building materials and can withstand loads of up to 7 tons per 1 sq.m.

The production of insulation from two types of raw materials and a naturally large assortment make Isover a leader in the market of thermal insulation materials. Not only professionals, but also inexperienced craftsmen who want to do the insulation work themselves can find the right solution.

The building materials market nowadays offers such a wide variety of insulation materials that it often even makes it difficult to choose. They differ in the base material and form of manufacture, in the area of ​​application and, of course, in the reputation of the manufacturing company. The cost of insulation is often quite considerable, so it is understandable that consumers want to give their money for a guaranteed quality product. This means that it is best to choose the original products of well-known brands, among which “Isover” (in Russian transcription - “isover”) is one of the leaders in terms of the effectiveness of thermal and sound insulation of buildings, and in terms of its reliability and durability.

Isover insulation, the technical characteristics of which will be further discussed in this publication, is widely used in various fields. Materials of this trademark They are famous for their effective protection of residential, public, industrial, and utility buildings and structures from cold, heat and external noise, and there is no doubt about their high quality.

A few words about the insulation manufacturing company “Isover”

The manufacturer “Isover” is a company that is part of the largest international association “Saint Gobain”, which produces a huge and comprehensive range of modern building materials. "Saint Gobain" unites more than a hundred industrial companies and organizations engaged in innovative developments in the field of construction. It’s hard to even imagine, but the history of this manufacturer dates back to the 17th century - are there many companies in the world that have already celebrated their 350th anniversary?!

Vast, centuries-old work experience, the ability to properly organize the activities of all levels, constant independent development innovative technologies and much more - all this is the basis of the fact that the manufacturer has become the undisputed leader in the production of materials that allow creating zones of the most comfortable living space.

Saint Gobain works in a variety of areas. These are high-tech materials, ordinary flat glass and those created for special applications, construction products, which include insulation, plasterboard and other gypsum-based products, building mixtures, tiles and facade cladding, acoustic panels for walls and ceilings, complex drainage systems, water and sewer pipes, and much more.

In addition to the Isover insulation materials discussed in this publication, which are produced in various modifications, the company also produces technical thermal and sound insulating materials under the Isotec and Isoroc brands.

The company has been operating in Russia for more than 20 years, producing various building materials, including mineral insulation based on basalt and fiberglass. The plant for their production has been operating for more than 10 years in Yegoryevsk (Moscow region), and in 2011, as part of a business expansion strategy, Saint Gobain acquired the Minvata plant in Chelyabinsk, which, after a radical re-equipment, is now Insulation is produced based on stone fibers.

All enterprises of this association successfully undergo certification of the international standard of environmental management, therefore insulation products are considered environmentally friendly products. The company puts its products in the same group for their environmental friendliness as materials such as linen and cotton, and they comply with European and international standards - EN 13162 - ISO 9001, as well as the Saint Gobain group's own, extremely strict standards.

Main types of thermal insulation “Isover”

So, insulation materials from this manufacturer can be made from glass or basalt fibers. Such specific structures are obtained by processing quartz sand, broken glass or mineral rocks of the basalt group - melting them and then stretching them using TEL fiberization technology. The resulting thin, almost microscopic threads with a thickness of 4–5 microns and a length of 110–150 microns are connected to each other with special resins.

Mineral insulation"Isover" are produced in mats, which are then rolled into rolls, and in slabs. Both can have different thicknesses and several linear dimensions, depending on their purpose and recommended installation technology.

The main lines of this material are divided into types according to their areas of application in construction and into universal ones. For example, the purpose of many insulation materials is clear from the name:

• "Isover Warm Home Stove"
• "Isover Warm Home"
• "Isover Warm walls"
• "Isover Warm Roof"
• "Isover Sauna"

And the following types can be safely classified as materials of universal purpose:

• "Isover Optimal"
• "Isover Pro"
• "Isover Classic"
• "Isover Extra"

Each of the above insulation materials has its own characteristics that correspond to its area of ​​application. They will be discussed below.

In addition, Isover produces heat and sound insulators for floors, interior partitions, ceilings and suspended systems, and materials for walls are divided into those used for internal surfaces and for building facades.

There is another criterion for the division of insulation materials “Isover” - by rigidity. The designation has alphabetic symbols applied to the packaging, and its interpretation is given in the table below. This parameter is closely related to such characteristics as the density of the material, its thermal conductivity, and the degree of its compression in the original packaging (many types, after opening the packaging, significantly increase in thickness of the plate or mat).

Table of division of “Isover” insulation by degree of hardness:

Insulation marking	Average density, kg/m³	Thermal conductivity coefficient, W/m×°K	Compression ratio in original packaging
KT-II– elastic mats in rolls	11÷13	0,041	1:4
CT– elastic mats in rolls	17	0,036	1:4
KL-A– elastic plate	17	0,041	1:1,5
KL– elastic plate	19	0,033	1:1,4
RKL– rigid board reinforced with fiberglass on both sides	60	0,030	No
RKL-A– windproof rigid slab (with tongue-and-groove connection)	60	0,030	No
RKL-EJ– plate of increased rigidity (with tongue-and-groove connection)	95	0,031	No
SKL– semi-rigid slab	50	0,031	No
VKL– hard plate	130	0,032	No

General advantages and disadvantages of Isover insulation

Before moving on to a detailed examination of the technical characteristics of each type of Isover insulation, it makes sense to obtain information about their general features that are inherent in each of these products.

The positive characteristics of this material include the following qualities:

• Low thermal conductivity allows the heat generated by heating units to be retained in the house for as long as possible, which means that less fuel will be spent on heating the building, and the owner will save a decent amount on its payment.
• A high level of absorption of sound waves - this quality will reliably protect the house from external noise, and rooms (when using the material in the construction of partitions) from extraneous internal sounds. Good performance is achieved thanks to the structure of the material, since the air gap between the fibers is capable of absorbing vibrations. Any, in fact, of the Isover insulation performs two functions at once: it thermally insulates the room and makes it as quiet as possible. But in addition, the manufacturer produces a material specifically designed for noise protection.
• A high level of vapor permeability is one of the most important qualities for insulation. This material is also called “breathable”, since it does not collect or retain moisture in its structure, which means that it will not create a favorable environment for the appearance of pathogenic microflora, and the walls will not become damp. In addition, the property of freely transmitting water vapor makes the insulation more durable in its direct functionality, since the thermal conductivity of an over-moistened material sharply increases, and it becomes unable to provide proper thermal insulation of building structures.
• The non-flammability of Isover heat insulators makes them absolutely safe. The material is classified according to the NG flammability scale, that is, according to the highest level of fire resistance, which means it can be safely used in the construction of frame, cobblestone and log houses.
• “Isover” - slabs and mats are lightweight, so they can be used for insulation of buildings in which excessive load on load-bearing structures is unacceptable.
• The service life of insulation, subject to installation technology and operating rules, is 50 years or more.
• “Isover” insulation materials are treated with water-repellent agents, that is, water-repellent compounds, so they have a fairly high moisture resistance.
• Affordable price. Compared to other similar materials, Isover products have a price that is quite acceptable for a family with an average income.

However, the heat insulators from this manufacturer also have their own “disadvantages”, which for some may be significant, so they also need to be mentioned:

• Since the binders for basalt and glass fibers are usually phenol-formaldehyde resins, the material cannot be called absolutely clean from an environmental point of view. The fact is that over time, such compounds can begin to release toxic fumes into the environment that are dangerous to human health.

Despite the fact that the manufacturer positions its products as absolutely “clean”, this still has to be treated with a certain amount of distrust. They have not yet gotten rid of binding resins - and although the emission of formaldehyde has indeed been reduced to a possible minimum, it is too early to talk about its complete absence.

It should be noted here that almost all insulation of this type includes these binders. There are certain exceptions, but they are still so expensive that not every homeowner can afford such thermal insulation.

• Despite the fairly high moisture resistance, it is impossible to exclude waterlogging of the material in direct contact with water. Thus, a thermal insulation structure, for example, on a facade or on a roof, must also include a reliable waterproofing layer.
• Since for the manufacture of any mineral wool the finest fiber is used, which has a relative rigidity, during installation its smallest particles can get into the respiratory tract and eyes, as well as stick into open areas skin. Therefore, this factor complicates the process somewhat. installation work due to the need to use protective equipment.

In addition, when insulating a house internally, mineral wool must be hermetically sealed with a dust-proof material so that fiber particles do not enter the air of living spaces.

• The manufacturer calls the advantage of insulation materials their non-flammability. However, it should be noted that some types of insulation (this applies to a greater extent to foil ones) are not non-flammable, but self-extinguishing, that is, they do not allow fire to spread. They can be used for buildings raised from any material, but at the same time complying with the requirements for ensuring fire safety, prescribed in SNiP 01/21/97.

Characteristics of thermal insulation materials “Isover” and recommendations for their use

Now, having familiarized yourself with the information about the main “pros” and “cons” of “Isover” thermal and sound insulators, you can move on to considering the detailed technical characteristics of each of them.

Prices for “Isover” insulation

Isover insulation

Universal insulation materials "Isover"

The company produces not only insulation materials for narrowly targeted applications, but also universal ones that can be used for different building structures. These materials include: “Optimal”, “Profi”, “Classic” and “Extra”, as well as “Warm House Stove” and “Warm House”.

Their technical and operational characteristics are given in the table:

	"Isover Optimal" (stove)	“Isover Pro” (mats in rolls)	"Isover Classic" (slabs)	“Isover Classic” (mats in rolls)	"Isover Extra" (stove)

"Isover Optimal"

“Isover Optimal” is a universal material made from basalt fibers, which is used for insulation and sound insulation of all parts of the structure. frame house A In addition to the foundation, this includes the roof, floors, walls, partitions and floors along the joists.

In this option, in accordance with its name, we found the optimal combination of various material qualities:

— low thermal conductivity and excellent elasticity;

— simple installation that does not require additional fasteners;

— multifunctionality of use;

• The first step is to install timber racks with a pitch of 590 mm on the insulated surface or in the frame. This “clear” distance will help the slabs of heat and sound insulating material to securely fasten against each other. The thickness of the beams of the racks or logs should be equal to the thickness of the heat insulator.

• The next step is to install insulation boards between the sheathing elements in one or two layers, which need to be pressed at the ends.
• If the wall of a frame house is insulated, then the insulation is covered with a wind-waterproof membrane on the outside, and with a vapor barrier film on the inside. These materials are stretched horizontally along the frame, starting from the bottom line of the wall, and secured to the frame posts using staples and a stapler. The top sheet must be overlapped with the bottom sheet by 120÷150 mm; the joints of the membranes must be sealed by gluing moisture-resistant adhesive tape on them.
• After this, a counter-lattice is attached to the frame, on top of the film, onto which the facing material will be fixed. Thanks to this approach, a ventilation gap is created between the insulation and the decorative finish, facilitating the spontaneous removal of water vapor and evaporation of condensate.
• The final stage is to attach it to the frame structure, first from the street side, then from the inside of the house.

"Isover Pro"

"Isover Pro" is made from fiberglass in the form of mats rolled into rolls. This insulation is also universal, as it can be used for thermal insulation of roofs of various shapes, walls inside and outside, frame walls, attic floors, floors, suspended ceilings, as well as sound insulation of interior partitions.

This insulation has its own advantages that distinguish it from other Isover products:

• “Isover Pro” has one of the lowest thermal conductivity values ​​of all materials from this manufacturer.
• Due to the fact that special markings are applied to the mat, it is convenient to cut. At the same time, even if a non-standard structure is insulated, a minimum of waste remains from the material.
• The insulation is produced in different thicknesses - 150, 100 and 50 mm.
• This version of the heat insulator belongs to the “NG” group in terms of flammability.
• The manufacturer positions it as a material safe for human health.

Installation work using this material is easy and quick, since the roll on the packaging has the markings necessary for cutting. Therefore, the mats are cut to the required width without unrolling the roll.

• The first step is to install racks with a standard pitch of 600 mm for sheathing. The roll width is 1220 mm, it is cut in half and two strips 610 mm wide are obtained. Thanks to this size, the mats will be tightly installed between the racks or laid apart between the joists.
• The cut roll is released from the packaging, unfolded and installed between the frame elements. If the insulation strip is not additionally cut across the slabs, this will help avoid the formation of cold bridges.
• The non-standard arrangement of the frame posts will complicate installation. In this case, before cutting the mat, it is necessary to measure the distance between the frame elements, not forgetting to add 5 mm to the resulting distance for spacer on each side.
• If insulated or attic structure, then before installing the insulation, a windproof film is fixed to the outside of the roof.
• After the Isover insulation is installed, it must be tightened from the inside with a vapor barrier, the membrane of which is stretched horizontally, starting from the attic floor.

"Isover Classic"

Due to the fact that “Isover Classic” is universal, it can be used to insulate almost all building structures, excluding the base, foundation and surfaces that bear high loads. They provide heat and sound insulation frame structures- partitions and external walls, roofs and ceilings, ventilated facades and joist floors.

“Isover Classic” is a fiberglass insulation produced in the form of mats in rolls and slabs, with low rigidity. This means that it has a pronounced porous structure, which makes this material a good insulator.

However, this type of insulation does not have high strength characteristics, and therefore is not suitable for installation under screed and for finishing walls with plaster. If you plan to use it to insulate the facade, then only under materials such as siding, lining or slabs fixed to the sheathing.

"Isover Classic" has the following distinctive features:

• A layer of this insulation 50 mm thick is equivalent in terms of heat conservation to brickwork 950 mm thick.
• By using “Isover Classic” as home insulation, you can reduce the cost of heating a building by 40–45%.
• The material performs two functions at once - protecting the house from cold and external noise.
• The slabs are installed without the use of additional fasteners - they are installed between the elements of the sheathing or joists and fit tightly to them, eliminating the occurrence of cold bridges.

• If the floor is insulated using joists, it is recommended that they be secured to glassine previously spread on the base.
• The width of the Isover Classic slabs is 610 mm, and the width of the mats is 1220 mm, so the distance between the floor joists or sheathing posts should be 600 mm.
• The roll is cut crosswise in half when packaged. The manufacturer prudently puts markings on the packaging that will make it easy to navigate when cutting the material.
• Then, the insulation boards are laid, and the mats are rolled out between the wooden structural elements. Due to the fact that the heat insulator is 10 mm wider than the distance between the joists, it will fit snugly between them.
• The insulation should fill the entire space between the beams. Only in this case can the desired effect of heat preservation and protection from outside noise be achieved.
• If the insulation is installed in two layers, then the mats of the second layer must be laid or installed with their joints offset by 120÷150 mm relative to the first.
• It is recommended to use the material in combination with a wind-waterproof film and a vapor barrier membrane.

"Isover Extra"

“Isover Extra” is an insulation made of fiberglass in the form of slabs that have increased elasticity with a 3D effect, which allows the material to expand after being compressed, filling all the free space between the beams or metal profiles in plasterboard systems. In addition, the slabs fit tightly to the wall when insulating vertical surfaces, and are also tightly connected to each other at the joints, which completely eliminates the appearance of cold bridges.

Thanks to these features, “Isover Extra” insulation is universal and is used for thermal insulation of walls from inside rooms, facade surfaces for covering them with brick, siding, lining and decorative slabs, roofs of various modifications.

“Isover Extra” has a thermal conductivity coefficient of 0.034, which makes it one of the most effective heat-saving insulation materials presented by Isover - its use reduces heat loss to a minimum.

Installation of this type of insulation is carried out according to the manufacturer’s recommendations given above, taking into account the width of the slabs and the distance between the frame elements. The only thing I would like to add is that, thanks to the 3D effect, there is no need to level the insulated surface for installation of “Isover Extra” - due to expansion, it will fit tightly to it.

"Isover Warm House Stove" and "Isover Warm House"

These two thermal insulation materials can also be called universal, since they are suitable for installation on most construction sites. Their main characteristics, which differ slightly from each other, are shown in the table:

Basic parameters of insulation	"Isover Warm Home"	"Isover Warm Home Stove"
Thermal conductivity coefficient, at 10˚С, W/m×˚С	0,040	0,040
Airborne noise insulation index Rw (dB)	45	45

Width, mm	1220	610
Length, mm	5490 and 7000	1170
Volume of insulation in packaging, m³	0.67 and 0.85	0.5 and 0.5
Insulation area in packaging depending on thickness, m²	13.4 and 17.1	10 and 5
Number of mats per package, depending on thickness, pcs.	2 and 2	14 and 7

“Isover Warm House Stove” and “Isover Warm House”, as can be seen from the table above, have the same physical and operational characteristics and differ only in linear dimensions and volume. Both materials are made from fiberglass obtained by processing a specially selected mixture of limestone, sand and soda. However, it is more convenient to use slabs for insulation in one area, and mats in another.

• "Isover Warm Home Stove", as the name suggests, is produced in slabs, which are more convenient to use for thermal insulation of vertical surfaces, both inside and outside, as well as for insulation with them

• "Isover Warm Home" It is produced in the form of mats and is sold in rolls. This modification of the insulation is perfect for installation on horizontal surfaces. Yes, they isolate interfloor ceilings, they will well insulate floors above a cold basement, but they are mounted only between the joists, and this material is not suitable for screeding.

Having dealt with the universal “Isover” insulation, you can move on to considering those that are intended for specific areas of the building.

Isover mineral wool for specific applications

For individual areas of thermal insulation of buildings, the manufacturer has developed several types of specific materials. Therefore, to make it easier to understand their models, they should be combined into groups.

Insulation of the facade for further plastering

To insulate this part of the building, several “Isover” materials are used - these are “Facade-Master”, “Plaster Facade”, “Facade” and “Facade-Light”. Each of them is designed for specific surfaces, so their characteristics differ from each other:

Basic parameters of insulation	"Isover Facade-Master" (slab)	"Isover Plaster Facade" (slab)	"Isover Facade" (slab)	“Isover Facade-Light” (slab)
Thermal conductivity coefficient, at 10˚С, W/m×˚С	0.036÷0.040	0.038÷0.040	0.037÷0.042	0,034

• - this is insulation made from basalt fiber ( stone wool), goes on sale in slabs of different thicknesses. The material is intended for insulating the facade of residential buildings up to 16 meters high, under thin-layer plaster.

Prices for “Facade-master” plaster

Facade master

• It is produced in slabs of glass fiber and is an innovative material for insulating the outside of a building. This material has a more affordable price than the previous one, but is also intended for installation under finishing plaster solutions, which will be applied to their surface in a thin layer.

• are produced in the form of slabs of basalt fiber, and are intended for insulation of facades. The material is usually laid with the expectation of subsequent finishing with decorative plaster.

• - this option facade insulation made of fiberglass is used for low-rise buildings and is installed under the finishing with a thin layer of plaster. The material is well suited for insulating country houses and cottages. The insulation is characterized by high strength and rigidity, however, it has less weight compared to insulation for a similar purpose.

• Work on insulating the facade using the “wet facade” technology, that is, with subsequent plastering, must be carried out at a temperature not lower than +5 degrees, having previously protected the walls from possible direct ingress of water. Usually, for this purpose, a temporary structure is installed from timber or metal profiles, which serves as a frame for polyethylene film.
• Installation of insulation begins from the bottom of the wall. The slabs are fixed to a pre-primed and dried wall using an adhesive solution. The solution must be applied to the surface of the slab so that contact is ensured on at least 40% of the total area of ​​the slab.

• The plates are glued to the wall, pressed tightly against each other. If, due to the incorrect “geometry” of the walls, gaps of more than 2 mm are formed between them, they must be filled with strips of the same insulation.

• After the glue has dried, the insulation is additionally fixed to the wall with special fasteners, the so-called “fungi”.

• The next step is to cover the insulated surface of the wall with a thin layer of adhesive so that the relief of the slabs can be seen through it. Usually the same glue is used as when installing slabs. After this, a thicker layer is applied, about 3÷5 mm, and it is recommended to go over it with a notched trowel with a low comb.

• After this, without a pause, a reinforcing material is attached to the prepared surface. fiberglass mesh, which is embedded in the distributed solution using a spatula (trowel). The mesh must be completely immersed in the solution.
• Next, they proceed to applying a thin (about 3÷4 mm) base plaster layer. This may be a special composition intended specifically for “wet facades”, or again the same installation adhesive for mineral wool. This layer is leveled, smoothed, and when ready, primed with a special composition for a specific type of decorative plaster.
• After the base plaster layer has dried, decorative plaster can be applied to it.

Materials for insulating walls inside and outside

The next line of Isover insulation includes products designed for thermal and sound insulation of walls both inside and outside. These include such universal materials as “Isover Pro” and “Isover Classic Plate”, the characteristics of which are described above, as well as “Isover Warm Walls”, “Isover Warm and Quiet Wall” and “Isover Standard”, the parameters of which are presented in the following table:

Basic parameters of insulation	"Isover Warm Walls" (slab)	“Isover Warm and Quiet Wall” (mats in rolls)	"Isover Warm and Quiet Wall" (slabs)	"Isover Warm and Quiet Wall Plus" (slabs)	"Isover Standard" (slabs)

"Isover Standard"

“Isover Standard” are slabs made from basalt fibers, which are used in multi-layer insulating structures in which the decorative finishing is a block house, siding, lining, facing bricks, and other similar materials. In addition, “Standard” slabs are also suitable for thermal insulation of frame structures, as well as for attic and pitched roofs.

• The material has medium density, so it is not suitable for installation under plastering walls.
• The good elasticity of the insulation ensures its tight fit to the surfaces of the walls and frame structure.
• Increased tensile and strength parameters ensure reliable fixation of the plates using special clamping “fungi” fasteners.

"Isover Warm Walls"

“Isover Warm Walls” are heat and sound insulating boards made of glass fibers, reinforced with water-repellent treatment.

This type of insulation is used for thermal insulation of walls from the inside of a building and for external installation under siding, decorative boards, clapboard or facing bricks, as well as for installation in frame structures. In addition, the material is suitable for insulating roofs of various configurations, as well as loggias and balconies.

• The insulation boards are quite resilient and elastic, so they adhere well between the frame posts and do not slip or break during installation.
• Increased moisture resistance allows the material to be used for insulating roofs and balconies.

"Isover Warm and Quiet Wall"

"Isover Warm and Quiet Wall" is made from fiberglass in the form of slabs and mats. Thanks to its porous structure, the material is able to perform two functions, which are reflected in its name.

This “Isover” option is used for internal and external wall insulation, as well as for frame buildings.

• “Isover Warm and Quiet Walls” has an increased vapor permeability parameter compared to other insulation materials, which allows it to “breathe”. Thanks to this quality, a favorable microclimate is created in the premises of the house.
• The materials have high elasticity, so they quickly expand in the frame, filling all the free space.
• When installing slabs or mats in any frame, they do not need to be additionally fixed, since they are perfectly held due to expansion when expanding independently.

"Isover Warm and Quiet Wall Plus"

This version of wall insulation is produced in fiberglass slabs and has characteristics similar to the materials presented above. But him distinctive feature is lower thermal conductivity and increased sound insulation index.

“Isover Warm and Quiet Wall Plus” is designed for insulating walls from the inside of a building, as well as outside under a decorative layer of siding, slabs, lining or facing bricks. In addition, using additional protective materials, such as wind-waterproofing and vapor barrier membranes, frame structures can also be insulated with these slabs.

Recommendations for internal wall insulation from the manufacturer

The work of installing insulating mats or slabs on walls between wooden studs or metal profiles is quite simple, with correct marking and installation of sheathing elements.

• The first step is to attach the sheathing to the marked wall. The racks are installed at a distance from each other depending on the width of the insulation material. So, if the width of the slab is 600 mm, then the racks need to be fixed in increments of 590 mm.
• Next, insulating material is installed between the fixed posts. It can be installed in one or two layers, depending on the required thickness.
• If a metal profile is used for the frame, you may have to additionally fix the slabs on the wall with disc-shaped dowels - “fungi”. When installing timber sheathing, in additional fixation insulation is usually not necessary, since it is securely held due to self-expansion.

• After all the insulation is installed in its place, it must be covered from the room side with a vapor barrier membrane, which will additionally become a layer that will delay the spread of dust, and small particles from mineral wool fibers will not enter the air space of the premises. The membrane sheets are stretched horizontally, starting from the floor, each subsequent strip is overlapped by 120÷150 mm on the bottom, and their joints are sealed with adhesive tape.
• Next, plasterboard slabs, one of the types of lining or decorative slabs are attached to the frame elements.

When installing insulation using this technology on the external surfaces of walls, the work is carried out in a similar way, with the exception of some points. For example, instead of a vapor barrier, a wind-waterproofing diffuse membrane (which allows water vapor to pass through well) is stretched over the insulation instead of a vapor barrier, and counter-lattice slats are attached to the racks on top of it, which will create a ventilated gap between the insulation and the decorative sheathing. Thus, moisture will evaporate freely into the atmosphere.

“Isover” materials for roof insulation

To insulate the roof, the Isover company also provided several heat-insulating materials, and some of them have already been described above - these are the “Optimal” and “Profi” station wagons. In addition to them, there are highly specialized insulation materials “Isover Warm Roof” and “Isover Pitched Roofs and Attics”, the characteristics of which will be discussed further.

Basic parameters of insulation	“Isover Warm roof” (mats in rolls)	"Isover Pitched Roofs" (slabs)

"Isover Warm Roof" And "Isover Pitched Roofs"

Both materials are intended for insulation of roof slopes of different configurations, but have different characteristics in terms of release form, linear dimensions and material of manufacture. What they have in common is that insulation materials for this application undergo special treatment using AquaProtect technology, which provides the products with increased moisture resistance.

• "Isover Warm Roof" is made of fiberglass in the form of mats rolled into rolls. They go on sale in plastic packaging, on which markings are applied for ease of cutting the material according to its width.

• “Isover Pitched Roofs” - is made from basalt fibers in the form of slabs, which are compressed and also packaged in polyethylene.

These materials are suitable for thermal insulation of the surfaces of pitched and mansard roofs, and also, by the way, for the surfaces of walls inside and outside for cladding with decorative panels and facing bricks.

The procedure for installing insulation in rafter system roofs are described in the “Isover Pros” section

Insulation and soundproofing of the floor

In order to efficiently insulate floors, the manufacturing company has developed two types of special materials - “Isover Floor” and “Isover Floating Floor”, which have different technical and operational characteristics:

Basic parameters of insulation	"Isover Floor" (slabs)	"Isover Floating Floor" (slabs)
Thermal conductivity coefficient, at 10˚С, W/m×˚С	0,036	0,033
Airborne noise insulation index Rw (dB)	32÷36	37
Moisture absorption during partial immersion in 24 hours, kg/m², no more	1	1

Width, mm	600	1190
Length, mm	1200	1380
Volume of insulation in packaging, m³	0,173; 0,216; 0,216	0,197; 0,296; 0,296; 0,328; 0,328
Insulation area in packaging depending on thickness, m²	5,76; 4,32; 4,32	9,85; 14,78; 9,85; 8,21; 6,57
Number of mats per package, depending on thickness, pcs.	8,0; 6,0; 6,0	6,0; 9,0; 6,0; 5,0; 4,0

These materials have a common purpose, and therefore similar characteristics. When developing them, the manufacturer achieved an optimal combination of damping properties and mechanical characteristics. Both types of insulation are easy to install, but their installation technologies differ from each other.

The products not only insulate surfaces, but also significantly reduce the noise emanating from the insulated room to the one below, and back.

• "Isover Flor"- These are slabs made of basalt fiber with increased rigidity. They are used for arranging a floating floor, as well as a floor with joists. The design of a floating floor provides greater efficiency in creating a warm and quiet floor, since the insulation in it completely covers the entire surface. The material is adapted to high loads, so it can easily be laid under a concrete screed.

• "Isover Floating Floor"- this version of slabs made of glass fibers is intended to create a “floating” floor - a concrete screed that is not connected to the walls and base. For a tighter connection of the slabs to each other, the manufacturer, at the request of consumers, can produce products with a tongue-and-groove connection. However, jointed boards can only be used on a perfectly level surface.

The products have high strength characteristics thanks to the vertical fiber arrangement technology.

“Floating” is a floor structure that is not fixed to the base, for example, to a floor slab.

If you plan to make a “wet” cement-sand screed covering the insulation, then the slabs laid on the base must be covered with a layer of waterproofing. This material is intended to protect the insulation from moisture penetration from concrete mortar. Waterproofing sheets are laid with an overlap of 200÷250 mm. Waterproofing is also provided between the base and the insulation layer to prevent capillary penetration of moisture into the material.

In addition, when arranging any insulation, before installing insulation, it is necessary to install damper tape or narrow strips cut from insulation, 10÷12 mm thick, and a height that will exceed the level of the screed by 120÷150 mm.

After the screed has hardened, it will be easy to cut off the excess damper strip. This element of the “pie” structure will enhance sound insulation, since the screed will not be adjacent to the walls and will not directly transmit noise vibrations. In addition, such a damper will keep the screed intact during linear expansion caused by temperature changes.

Isover materials for sound insulation of buildings

To protect the house from external and internal noise, the company produces two types of specific materials - “Isover Quiet House” and “Isover Sound Protection”. However, in addition to them, the aforementioned universal insulation materials “Classic” and “Pro”, which have characteristics quite suitable for this purpose, can also be used for this purpose.

Basic parameters of insulation	"Isover Quiet House" (slabs)	"Isover Sound Protection" (slabs)
Thermal conductivity coefficient, at 10˚С, W/m×˚С	0,038	0.038÷0.044

Number of mats per package, depending on thickness, pcs.	14,0	14,0; 7,0; 20,0; 16,0; 10,0

• "Isover Quiethouse»

“Isover Quiet House” - this heat and sound insulator, made of fiberglass, goes on sale in plastic packaging. The material has a high noise absorption index, therefore it is an excellent remedy for soundproofing walls and interior partitions.

In addition, the slabs are laid on horizontal surfaces - between floor joists, attic floor beams, in the space between the suspended ceiling and the floor slab, etc. Such installation will make the rooms not only quiet, but also warm, since the material performs two functions at once.

• "Isover Sound Protection"

“Isover Sound Protection” are slabs molded from basalt fiber that have pronounced elasticity. Thanks to this quality, they are easy to install in a frame sheathing, installed as a partition or mounted on a wall.

Soundproofing boards can be used in combination with other insulating materials, installing them in two layers. This design will be especially effective for frame partitions.

This material is also perfect for attic floors, since the soundproofing layer will not only prevent entry into the house extraneous sounds, but will also retain the accumulated heat, preventing it from escaping through the ceiling.

Most often, walls and partitions insulated with slabs are sheathed, since it is best suited for such structures.

• The slabs must fit tightly to each other or to the sheathing elements, since even small gaps can significantly reduce the level of sound insulation.
• It is best to cover an insulated wall plasterboard sheets- it also absorbs sound waves quite well and resonates much less compared to wood-based sheets - plywood, fibreboard, chipboard, OSB, etc.
• Before sheathing with plasterboard, mineral wool must be covered with a material that does not allow dust, along with microscopic fragments of fibers, into living spaces. At the same time, such a membrane must act as a vapor barrier.
• If metal profiles are used for the frame, it is recommended to stick vibration-isolating tape on their outer surface before fixing the drywall, which will also help reduce the noise level.
• The gaps allowed between the plasterboard sheets will reduce the soundproofing effect, so during installation you should try to ensure that they are not more than 2÷3 mm. If this cannot be achieved, it is best to use silicone and acrylic-based sealants to seal them, since they also have a soundproofing effect, do not crumble and adhere securely to the surface.

Materials for thermal insulation in baths and saunas

For insulation of saunas and baths, in the range of materials from this manufacturer you can find a specific offer - these are rolled mats with the characteristic name “Isover Sauna”.

This material is made from fiberglass and has a foil coating on the front side. The main characteristics of the “Isover Sauna” are presented in the table:

Basic parameters of insulation	"Isover Sauna", mats in rolls
Thermal conductivity coefficient, at 10˚С, W/m×˚С	0,041
Airborne noise insulation index Rw (dB)	54
Moisture absorption during partial immersion in 24 hours, kg/m², no more	1
Vapor permeability mg/m×h×Pa	vapor-tight
Insulation density, kg/m³	30
Flammability group	G1 based on NG
Thickness, mm	50;100
Width, mm	1200
Length, mm	12500; 6250
Volume of insulation in packaging, m³	0,75
Insulation area in packaging depending on thickness, m²	15,0; 7,5
Number of mats per package, depending on thickness, pcs.	1,0

The features of this thermal insulation material include the following points:

• The mats consist of two layers: the main one, made of mineral wool based on fiberglass, and the outer one, made of foil. At the same time, mineral wool is characterized as a non-flammable material, and the foil coating belongs to the G1 flammability class, as it can withstand temperatures on the surface of up to 100 degrees, largely due to the layer of glue that holds the foil. With higher heating, this layer loses its elasticity and, when exposed to direct flame, can ignite, although it is self-extinguishing. To prevent this from happening, and also to make the walls decorative, they are usually lined with wooden clapboard.
• “Isover Sauna” takes on two functions: it is a good heat insulator and at the same time a vapor barrier that protects the mineral layer from abundant evaporation, which is an integral part of a bath or sauna.
• The foil layer has the property of reflecting heat from the walls back into the room, which significantly increases heat conservation, which is so important for bath conditions.

To understand the installation process, you can consider approximate diagram installation materials:

• The wall of a log house (there may well be any other wall of the bathhouse).
• Timber frame sheathing. IN in this case it is installed horizontally, but this is not important.
• Insulation "Isover Sauna".
• Spacer strips creating an air gap.
• Internal lining of premises made of natural lining.

Installing “Isover Sauna” on walls is not very different from installing conventional insulation, except for some nuances:

• The material is mounted between the racks in a spacer, with the foil side facing the inside of the room.
• The joints of the heat insulation plates with the guides and among themselves, as well as the remaining open front part of the guides, must be sealed with foil adhesive tape.

• Mats need to be cut only very sharp knife, otherwise the cuts will turn out uneven and when installing insulation between the racks, unacceptable gaps will form.
• Counter battens perpendicular to the guides are installed on top of the insulation. They will additionally press the insulation to the wall, create a ventilation gap between the foil surface and the decorative cladding, and become the basis for attaching the cladding. The thickness of the slats must be at least 25÷30 mm.
• The final stage is covering the wall with clapboard, which is fixed to the counter-lattice slats.

What thickness of Isover material is required for effective thermal insulation?

We hope that after familiarizing ourselves with the range of Isover insulation materials, the purpose and characteristics of each type, the interested reader will be able to choose optimal material for your needs. But here’s another question: how thick should the insulation be for it to really fulfill its role, so that a comfortable microclimate is maintained in the rooms?

To determine this, you will need to do some thermal calculations. Usually they are carried out by socialists, but for a private developer a somewhat simplified algorithm for determining the thickness of thermal insulation is sufficient. Let's try and you will see that everything is not so complicated.

The calculation is based on the fact that any building structure of a residential building must have a certain parameter– resistance to heat transfer. This value (R) is expressed in m²×°C/W, and the larger it is, the higher the thermal insulation capacity of the structure.

Specialists in the field of construction and heating engineering carried out the necessary calculations, on the basis of which standardized values ​​of thermal resistance were established for various regions of the country, in accordance with their climatic characteristics. This suggests that in order to maintain an optimal microclimate in residential premises at any time of the year, it is necessary that the heat transfer resistance of building structures be at least not lower than the normalized one.

The corresponding tables of normalized values ​​are in SNiP, but it will be more convenient to use the diagram map given below.

There is a special formula showing the relationship between the thermal conductivity coefficient of any material, the thickness of its layer, and the resulting heat transfer resistance.

R=h/λ

R– required heat transfer resistance;

h– thickness of a specific layer;

λ – tabular value of the thermal conductivity coefficient of the material from which the calculated layer is made.

• Thus, knowing, for example, the thickness of the wall that requires insulation and the material it is made of, it is not difficult to find what thermal resistance it provides.
• The same calculations are made for other layers of the structure if they affect the overall insulation of the wall. After layer-by-layer calculation, the values ​​are summed up.
• Then the total value must be compared with the normalized value established for your region. The result will be a difference (usually quite impressive), which the insulation material must make up for.
• Well, knowing the thermal conductivity coefficient of the selected insulation, it is easy to determine the required thickness using the formula.

“In words” may seem difficult to some, but with our online calculator, which takes into account the necessary table values ​​and enters the necessary dependencies, the calculation will not be difficult.

The article will discuss what isover insulation is, how it is produced, what technical characteristics it has, what disadvantages the products of the French concern “Saint-Gobain” have, what types of presented material are most popular in our domestic market. Photos and videos will reveal the nuances of installing slabs and rolls.

What is isover

Isover is a material that is used to insulate flat surfaces. It is produced by the French company Saint-Gobain. The name of the insulation comes from two French words “isolation” - insulation and “verre” - glass. It explains what it is made of. There are two forms of French insulation on the domestic market. There are slabs and rolls. They are formed using fiberglass and basalt wool. Each variety has its own technical characteristics. They determine the scope of use.

The basis of the material is fiberglass and basalt wool. When making slabs or rolls, recycled soda, limestone and sand are added. The use of recycled materials allows us to reduce the cost of the finished product, so French insulation has a very affordable price.

The manufacturing technology of isover is extremely simple:

Listed Components recyclable materials are mixed among themselves, to them are added other minerals, mixture heats up up to 1300C and transforms into a plastic mass, similar to liquid glass.

She poured into the tank. In its walls there is microscopic holes.

Capacity unwinds like a drum and spins with high speed. Centrifugal force forces the loaded substance through microscopic holes. In this manner the thinnest threads are formed.

The threads are mixed with a special adhesive composition . A viscous mass is formed.

She goes to oven-dryer.

There the workpiece passes through the rollers. With their help formation is formed.

At the final stage he cut into required dimensions. The maximum possible dimensions are 610x1170 mm, the thickness of the slab can vary from 5 to 10 cm.

Specifications

The material obtained by the method described above has unique properties. The layers have high elasticity, low thermal conductivity (0.041), and low weight. For insulation materials, these characteristics are very important. If installed correctly, the technical characteristics do not change over time, which ensures maximum heat savings throughout the entire operation of a residential or industrial building.

Air bubbles remain between the fibers. They prevent sound penetration. Therefore, using isover for insulation, you can significantly improve the sound insulation of a building. The manufacturer recommends using this material where it is necessary to increase sound insulation without increasing the load on existing surfaces.

The slabs can additionally be treated with water repellents. They make the insulation surface waterproof. When burning, isover does not contribute to the spread of fire; the material has low smoke-generating ability.

On a note! Isover is ideal for insulating log structures, frame or panel houses.

When packaging, the mats are pressed. As a result, their volume is reduced by 60%. This greatly facilitates the transportation of insulation. After removing the packaging, the mats easily restore their shape. They can be used for external and interior decoration. During operation, no hazardous chemical elements are released from the surface of the isover. No formaldehyde or resins are used in its production. Therefore, the material described belongs to the class of environmentally friendly.

Existing varieties and scope of application

The French concern Saint-Gobain produces various types of insulation materials. Nine types of isover are most popular on the Russian market:

Thermal insulation isover KL 34 – unpressed slabs, which have a very wide range of applications, are used for insulation of any vertical And horizontal surfaces. For installation it is being built wooden sheathing. The plates are inserted inside it without additional fastening.

Isover KL 37 – pressed slabs laid in packaging. Used for insulation floors between two adjacent floors, internal walls and roof slopes.

Important! When installing the plates, they must be pressed tightly against each other.

IsoverKT 37 – roll thermal insulation. Used for insulation horizontal surfaces. Izover of this form can also be installed on walls, but only if it is necessary to insulate internal partitions.

IsoverKT 40– two-layer rolls used for insulation ceiling and floor.

Isover « STYROFOAM» 300A material to which structure has been added expanded polystyrene. These are slabs increased rigidity. They are attached to the surface using plastic dowels or special adhesives based on bitumen mastics.

Isover « VENTITERM» – additionally processed slabs water repellent. This New Product, it is still just conquering the market. Its scope of application is insulation facades carried out using the installation of single-layer or two-layer systems.

Isover"sound protection"– a material intended for soundproofing premises. Produced in the form of 5cm thick slabs, it can be used in any climatic zone. Using it, you can improve the sound insulation of the roof, internal and external walls.

Isover"Ventfacade"– two-layer slabs designed for insulation ventilated facades.

Choosing French insulation has its drawbacks. They must be taken into account when purchasing insulation. Since it contains fiberglass, you can only work with the material using protective equipment. You must wear gloves on your hands, pants and a jacket with long sleeves on your body, glasses on your eyes, and a gauze bandage on your face. If this safety precaution is ignored, any contact with the mats or rolls will cause severe skin irritation.

During operation, dust may be emitted from the isover. It will definitely contain particles of fiberglass. Their entry into the human body can provoke the development of diseases. Therefore, when carrying out internal insulation it is important to cover the material before installation finishing coating(lining, drywall) with vapor barrier film.

Isover cannot boast of high mechanical strength, it is not capable of bearing a load, so improper installation often leads to deformation of the finish. Such defects are often used by insects and mice to colonize.

If the slabs have not been additionally treated with water repellents, they will absorb moisture well. It lingers in the inner layers for a long time, causing the properties of the material to change.

On a note! When the moisture content of fiberglass increases by 1%, the thermal insulation decreases by 10%.

Technology for laying isover from inside walls

To lay mats, it is necessary to construct a sheathing. This can be done using wooden beam or metal profiles used for laying drywall. The pitch of the sheathing should be a centimeter narrower than the width of the insulation. Due to their high elasticity, the slabs are easily inserted into the space between two guides and adhere very tightly to the surface.

The top of the insulation must be covered with a layer of vapor barrier. The film is laid overlapping, the joints are additionally secured with a special vapor barrier tape. The top of such a structure can be covered with plasterboard or the lining can be installed immediately.

Video description

The video shows the technology of insulating the walls of a frame house with isover:

Technology for installing isover on the side of the building facade

The sheathing is constructed in increments of a centimeter narrower than the width of the insulation. The slabs are laid inside, and a counter-lattice is attached on top. It should provide an air gap. A waterproof and windproof membrane is attached to it. And the finishing decorative trim (siding or lining) is already attached to it.

To build such a structure, a layer of vapor barrier is first spread on a reinforced concrete base, then an isover is laid on it. Waterproofing material is spread on top. The top of such a cake can be filled with concrete screed or covered with gypsum sheets. Even before starting work, damper tape must be glued to the walls along the entire perimeter of the floor. She will provide education technological gap, which will not allow noise to move across the floors. The width of the tape should exceed the thickness of the screed by 2-3 cm.
