On the market building materials Nowadays, there is such a wide variety of insulating materials that it often even makes choosing difficult. 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 specifications which will be discussed further in this publication, is widely used in various fields. The materials of this brand are famous for the effective protection of residential, public, industrial, utility buildings and structures from cold, heat and external noise, and in their high quality there is no doubt.
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-long experience, the ability to properly organize the activities of all levels, the constant independent development of innovative technologies and much more - all this is the basis for 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, regular flat glass and those created for special applications, construction products, which include insulation, drywall and other gypsum-based products, building mixtures, tiles and facade cladding, acoustic panels for walls and ceilings, complex drainage systems, plumbing 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 soundproofing materials under the brands "Isotec" and "Isoroc".
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.
Isover mineral insulation is 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 consideration of the technical characteristics of each type of Isover insulation, it makes sense to obtain information about them general features, which 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 somewhat complicates the installation process 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 fire safety requirements prescribed in SNiP 21-01-97.

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 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 distance “in the light” will help the slabs thermally and soundly insulating material securely fasten by surprise. 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 from the outside the insulation is tightened with a wind-waterproof membrane, and from the inside - vapor barrier film. 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. Top cloth must be overlapped on the bottom by 120÷150 mm, the joints of the membranes must be sealed by gluing moisture-resistant adhesive tape to them.
- After this, a counter-lattice is attached to the frame, on top of the film, onto which the facing material. Thanks to this approach between insulation and decorative finishing a ventilation gap is created, 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 various shapes, walls inside and outside, frame walls, attic floors, floors, suspended ceilings, as well as soundproofing 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 heat and sound insulate 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 |
| Moisture absorption during partial immersion in 24 hours, kg/m², no more | 1,0 | 1,0 |
| Vapor permeability mg/m×h×Pa | 0,55 | 0,55 |
| Insulation density, kg/m³ | 11,0 | 11,0 |
| Flammability group | NG | NG |
| Thickness, mm | 50 | 50 and 100 |
| 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. So, they insulate interfloor ceilings, they insulate floors above a cold basement well, but they are mounted only between 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 |
| Airborne noise insulation index Rw (dB) | 45 | 45 | 45 | 55 |
| Moisture absorption during partial immersion in 24 hours, kg/m², no more | 1,0 | 1,0 | 1,0 | 1,0 |
| Vapor permeability mg/m×h×Pa | 0,3 | 0,4 | 0,55 | 0,4 |
| Insulation density, kg/m³ | 125,0 | 80,0 | 125÷155 | 50,0 |
| Flammability group | NG | NG | NG | NG |
| Thickness, mm | 50, 100, 150,200 | 50, 100, 150 | 50, 100,150 | 50, 100,150 |
| Width, mm | 600 | 600 | 600 | 600 |
| Length, mm | 1200 | 1200 | 1200 | 1200 |
| Volume of insulation in packaging, m³ | 0,288 | 0,288; 0,288; 0,216 | 0,144; 144; 0,216 | 0,288; 0,216; 0,216 |
| Insulation area in packaging depending on thickness, m² | 1,44; 1,44; 2,16; 1,44 | 5,76; 2,88; 1,44 | 2,88; 1,44; 1,44 | 5,76; 2,88; 1,44 |
| Number of mats per package, depending on thickness, pcs. | 4,0; 2,0; 2,0; 1,0 | 8,0; 4,0; 2,0 | 4,0; 2,0; 2,0 | 8,0; 3,0; 2,0 |
- - this is insulation made from basalt fiber (stone wool), and is sold 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
- is produced in glass fiber slabs and is innovative material for insulating the building from the outside. This material has 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 insulation 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 wall surface with a thin layer adhesive composition, 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 the “wet facade”, or again the same assembly adhesive for mineral wool. This layer is leveled, smoothed, and when ready, primed 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 the following universal materials, like “Isover Pro” and “Isover Classic Stove”, 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
Work on installing insulating mats or slabs on the walls between wooden racks or metal profiles is quite simple, with proper 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, there is usually no need for additional fixation of the insulation, since it is securely held due to its 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.

"Isover Warm Roof" And "Isover Pitched Roofs"
Both materials are intended for insulation of roof slopes of different configurations, but have various characteristics, according to 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 pitched and mansard roofs, and also, by the way, for wall surfaces inside and outside for cladding decorative panels and facing bricks.
The procedure for installing insulation into the roof truss system is 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 |

| 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. Material adapted to high loads, therefore it may well be laid under a concrete screed.
- "Isover Floating Floor"– this version of slabs made of glass fibers is intended to create a “floating” floor – concrete screed, not connected to the walls and foundation. 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 do “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 the penetration of moisture from the concrete solution. 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 |
| Airborne noise insulation index Rw (dB) | 54 | 54 |
| Moisture absorption during partial immersion in 24 hours, kg/m², no more | 1 | 1 |
| Vapor permeability mg/m×h×Pa | 0,7 | 0,55 |
| Insulation density, kg/m³ | 15 | 15 |
| Flammability group | NG | NG |
| Thickness, mm | 50 | 50; 100; 50; 75; 100 |
| Width, mm | 610 | 610 |
| Length, mm | 1170 | 1170 |
| Volume of insulation in packaging, m³ | 0,5 | 0,5; 0,5; 0,714; 0,856; 0,714 |
| Insulation area in packaging depending on thickness, m² | 10,0 | 10,0; 5,0; 14,27; 11,42; 7,14 |
| 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 means 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 extraneous sounds from entering the house, 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 used for the frame metal profiles, it is recommended to stick vibration-proofing 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 silicone sealants to seal them. acrylic base, 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 good heat insulator and at the same time - a vapor barrier that protects the mineral layer from abundant fumes, which are 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 make 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 - heat transfer resistance. 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.
is one of the leading manufacturers of mineral wool fiberglass thermal insulation materials in the world. These insulation materials have proven themselves as quality products, with an optimal ratio of price and performance characteristics.
From this article you will learn what types of Izover thermal insulation exist, their characteristics, and how they differ from each other. We will also study reviews and find out why these mineral wool insulation materials are better than similar products on the market.
1 Scope of application of Izover thermal insulation
Thermal insulation materials from the French company Izover, in addition to excellent insulating abilities, also have good noise-reducing properties, which significantly expands the scope of their application.
3 Isover KL 34

"5 Isover KT37
Izover KT37 – roll thermal insulation material for insulation internal parts buildings made of concrete, brick, wood and aerated concrete. Consumer reviews indicate that it is perfect for insulating the inside of walls, attics, or interfloor covering and lag floor.
KT37 belongs to the category of soft thermal insulation; the material has a density of 15 kg/m3, which does not allow the use this material on surfaces experiencing severe mechanical stress.
Compared to the original volume of the roll, the packaged KT37 is compressed almost 2 times, which greatly simplifies its transportation; the volume of one package is 0.16 cubic meters, after opening - 0.71 cubic meters.
The thermal conductivity of Izover KT37, as well as comparable to other insulation products from this company, is 37 W/μ, which makes even single-layer insulation with this mineral wool quite effective.
The thickness of a KT37 roll can be 50 or 100 mm, length - 630 cm, width - 60 cm. The roll form of the insulation makes it possible to cover large surfaces much faster than can be done with slab material. In terms of flammability, the product is classified according to the European standard A1, which corresponds to our NG class (non-combustible material).
6 Isover KT40
Isover KT40 is a two-layer thermal insulation material, produced in the form of a roll, intended for insulating the walls of frame houses, installation in the middle of false walls and thermal insulation of free space inside hollow brick walls.
The thickness of the KT40 roll is 100 mm, and, thanks to the two-layer design, the product can be divided into two rolls of 50 mm each. The overall characteristics of KT40 are as follows: roll length – 700 cm, width – 61 cm, the area of one package of insulation is 17.08 m².
In terms of thermal insulation properties, KT40 is somewhat inferior to the rest of the company's products; its thermal conductivity coefficient is 0.04 W/μ.

“Isover” - we are walking towards warmth and comfort. Gone are the days when what the market of thermal insulation materials offers could once be counted on one hand. Technical progress and competition in the ranks of manufacturers have contributed to the fact that today the problem of choice has become more pressing problems where to find money to buy. To confirm these words, one can cite the fact that modern market material such as isover.
Isover insulation: let's get to know each other better
In its structure, this heat insulator is very close to classic mineral wool. And since it had a sufficient list of shortcomings, the manufacturers of the new product tried to minimize the “minuses” in their product and give the insulator new positive qualities.
Isover's structure consists of tiny fibers up to 150 microns long and up to 5 microns thick.
For reference
Micron (μm) is a unit of length used to measure microparticles. One thousand microns is equal to one millimeter.
Technologists from the French concern Saint-Gobain were the first to achieve such a finely structured substance. The discovery, as well as the technology itself, which received the abbreviation “TEL”, was quickly patented, which not only predetermined a favorable position in the market, but also predetermined dominance in the market.
The year was 1957. It was then that, based on minerals of the basalt group and quartz, a substance was obtained, similar in characteristics to that widely used at that time stone wool and even superior to them.
The appearance of a new insulating material on the market was truly stunning, and until 1980, Saint-Gobain had the status of the only manufacturer of thermal insulation materials in almost all of Europe.
Meanwhile, the laws of the market and competitors did not agree with this. Thus, resting on its laurels required Saint-Gobain to make more and more new decisions, expand its product range and conquer new markets. So in 1995, Izover came to Russia. In 2007, a Russian representative office and a plant for the production of heat-insulating materials “ISOVER” were opened in the city of Yegoryevsk. Today, its annual production volume is more than 70,000 tons, which is one of the best indicators in Europe.
Interesting fact
The insulation trademark belongs to the French concern Saint-Gobain. According to the latest Forbes ranking, it is one of the hundred richest companies in the world. One hundred and seventy thousand company employees in sixty-seven countries around the world ensure Saint-Gobain’s turnover of $40 billion.
Why is Izover insulation valued?
The main characteristics of Izover insulation include:
- Thermal conductivity;
- Sound insulation;
- Resistance to burning;
- Vapor permeability;
- Long service life;
- Environmental cleanliness;
- Convenient packaging form;
- Low specific gravity.
The laboratory determined thermal conductivity coefficient of the material isover is 0.041 Watt/sq. meter - today it is considered the best among competitors. It should be added that this coefficient remains unchanged even after years of operation.
The Izover texture provides for the presence of air layers, which provides the material with the ability to absorb sound. Thus, sheets and mats of this min. wool can guarantee acoustic comfort not only by attenuating unnecessary noise through internal partitions, but also to isolate extraneous noise from outside the building.
Events dedicated to compliance with all-Russian standards confirmed that Izovera belongs to the class of non-flammable substances. This made it possible to expand the applicability of this heat insulator for almost any facility - from industrial buildings to schools and kindergartens.
Vapor permeability is another property of the Izover material, where it has few competitors. The ability to absorb moisture and quickly release it is guaranteed by the presence of fiberglass.
It should be noted that the main purpose of Isover - to retain heat - is very dependent on the moisture content inside the substance. For example, increasing the humidity min. Vata by just 1% worsens his basic ability by 10%. An effective solution to this problem can be an air gap (2-3 cm) between the sheets of heat insulation.
The unique composition of the heat-insulating Izover guarantees the preservation of its qualities for almost the entire life of the building (40-50 years). In addition, glass fibers discourage insects and rodents from establishing their homes and nests in this heat insulator.
Types of packaging
A number of tests have confirmed the environmental friendliness of the isover heat insulator. This is confirmed by mandatory and voluntary certificates of compliance with environmental standards.
Of course, at different construction sites - be it external walls or partitions, floors or roofs, various designs may be convenient for use heat-insulating material. The Saint-Gobain company pays no minor attention to this. We list the most popular forms of packaging and sizes of its heat insulators.
The standard and most popular packaging of Izover is mats rolled into a roll. Here are its main dimensions:
- Thickness when unfolded - 50 mm and 100 mm;
- Blade width - 1220 mm;
- Mat length - 5490 mm and 7000 mm;
- Area - 6.7; 8.54; 13.4 and 17.1 sq.m.
The “mini-mats” package also claims to be the leader in popularity:
- Thickness -50 mm;
- Width - 610 mm;
- Length - 8200 mm;
- Area - 10 sq.m.
The “roof” package has a number of packages depending on the area of the insulated roof and the required degree of insulation:
- Thickness -50, 100, 150 mm;
- Width - 1220 mm;
- Length - 4000 and 5000 mm;
- Area - 4.88; 6.1; 12.2 m.
Another type of packaging that is revered by builders is “semi-rigid mats” - “warm walls”:
- Thickness - 50 and 100 mm;
- Width - 610 mm;
- Length - 1170 mm;
- Area - 5 and 10 sq. m;
- Pieces per package - 7 or 14.
So as not to spoil the mood
Since one of the main components of Izover is fiberglass, the technology of its use provides for some safety measures. So, in order for the installation of insulation to be absolutely safe, comfortable and enjoyable, you will need:
- Clothing that blocks access to exposed parts of the body;
- Light but dense fabric gloves;
- Glasses;
- Gauze bandage or respirator.
Isover today includes dozens of varieties of thermal insulation materials. To the credit of the company, Saint-Gobain never ceases to strive for excellence, modernizes production and improves technology. There are specialized options for heat insulators:
- For private and industrial housing construction;
- For thick walls and partitions;

Thus, any builder can find a solution for each project in the product line from the French leader in the production of thermal insulation. At the same time, be confident, because the quality of this material is confirmed by practice and experience of use around the world.
To summarize, we can conclude that a decision in favor of heat or sound insulating material under the “isover” brand is the right step towards quality and reliability, towards the warmth and comfort of your home.
Izover is a well-known brand that specializes in the production of building materials. This is the only brand in Russia that produces thermal insulation based on basalt and fiberglass. The range of products is quite wide, which opens up great opportunities in terms of insulation of both private and industrial buildings.
Description and Application
The presented material has many advantages and disadvantages of mineral wool. And this is not surprising, since their properties are quite similar. It is produced in the form of slabs, which can be either rigid or semi-rigid. There is also the opportunity to buy Izover in the form of rolls and mats. They are used in the arrangement of the roof and facades of the house, ceilings, walls and floors.
Izover is based on glass fibers, the length of which reaches 100-150 microns and the thickness of 4-5 microns. It is these parameters that allow the Izover heat insulator to obtain high levels of elasticity and resistance to loads. Competition may come from technical ones.

Specifications
Has a large number of advantages. Thanks to them, today it occupies a leading position among all other heat insulators. When choosing, pay attention to the following technical characteristics of Izover and:
- Izover- This is a thermal insulation material, so it is characterized by low thermal conductivity - 0.038.
- Excellent sound insulation performance.
- For the manufacture of insulation, fiberglass was used, which is not susceptible to bacterial or fungal infection. It is not affected by rodents and small insects.
- High moisture permeability. This indicator is a disadvantage. This is explained by the fact that the material has a porous structure.
- Low specific gravity– 13 kg/m3. Thanks to the small one, the process of installation, transportation and loading of material is simplified. Installation of insulation can be done with your own hands.
- Ecological cleanliness.
- High degree of durability from negative influence chemical substances.
- High ductility. Mats can be compressed up to 60%, and rolls up to 75%.
- Fire resistance.
The video shows the technical characteristics of Izover insulation:
If we talk about the size of the Izover material, it depends on the form of release. The thickness of the mat rolls can be 5.10 cm - single-layer option. And for a two-layer, the thickness of one layer is 5 cm. For roll type standard width is 120 cm, and the length is 7-14 cm. But the area covered can vary between 16-20 m2.
But what kind of insulation should be used under a ventilated facade is described in this article:

What you need to know when choosing insulation
Thermal conductivity coefficient (λ)
When choosing thermal insulation products, firstly, you need to pay special attention to such an indicator as the thermal conductivity coefficient - λ (lambda). The lower the lambda value, the better the house can be insulated, due to the fact that the thermal conductivity value reflects how much heat passes through the insulation per unit of time.
Thermal conductivity coefficient is measured as W/(m*K). (watt per meter per kelvin)
Types of thermal conductivity coefficient (λ)
Dry lambdas (installed by the manufacturer at the factory):
λ10 - thermal conductivity coefficient recorded at 10°C. An indicator declared by the manufacturer.
Wet lambdas (set by the manufacturer at different degrees of humidity):
λA and λB - thermal conductivity coefficients for different operating conditions (according to SP 50.13330.2012). Measurements are carried out by licensed laboratories at material humidity of 2% and 5%. The coefficient is used for thermal calculations in construction.
Choose insulation based on its thermal conductivity value, because the lower the coefficient, the more effectively the house will be insulated. For example, if the thermal conductivity value is 0.036, this will be enough for 50 mm of thermal protection to replace 95 cm of brick
Which insulation to choose: in slabs or rolls?
All ISOVER products have high elasticity, which means that the material holds tightly and stably without the use of additional fasteners. Both rolls and slabs are used in different designs. The shape is determined depending on the room.
- Convenience when insulating large surface areas, ease of installation due to the fact that one roll can be insulated large area Houses.
- When used, fewer joints appear, and therefore, air flow throughput decreases.
- Low material consumption.
- Suitable for non-standard rafter spacing, easy to cut to the required width.
- Recommended for insulating small rooms.
- Suitable for one person use.
- They are fixed by surprise without the use of additional fasteners.
