Isover insulation technical characteristics. Overview of thermal insulation isover. Pros and cons of insulation that you should remember

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. 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, 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, 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 materials 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 suspension 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 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 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)
	0.037÷0.040	0.036÷0.040	0.038÷0.041	0.038÷0.041	0,034

	8; 4	2 (20 slabs); 1 (10 slabs); 1 (8 plates)	14; 7	2	14; 7

"Isover Optimal"

“Isover Optimal” is a universal material made from basalt fibers, which is used for insulation and sound insulation of all sections of a frame house structure, except for the foundation - this is the roof, ceilings, 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. 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 will be fixed. Thanks to this approach between insulation and decorative finishing is created ventilation gap, 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 posts 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 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 wooden elements designs. 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 interior walls, facade surfaces for cladding with brick, siding, lining and decorative slabs, and roofs of various modifications.

"Isover Extra" has a thermal conductivity coefficient of 0.034, which makes it one of the most effective materials of the 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
Insulation index airborne noise 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 a more affordable price than the previous one, but is also intended for installation under finishing with plaster solutions that will be applied to their surface 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 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 fiberglass mesh is fixed to the prepared surface, 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 facade", or the same one again assembly 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 suitable for thermal insulation of frame structures, as well as for attic and pitched roof.

• 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 its distinctive feature is lower thermal conductivity and an 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 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, between the fixed racks it is installed insulation material. 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.

"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 wall surfaces inside and outside for cladding 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

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. 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 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 room, before installing the insulation, around the perimeter of the room it is necessary to install a 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)

• "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 suspended ceiling and 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 with plasterboard sheets - it also absorbs sound waves well and resonates much less compared to wood-based sheets - plywood, fiberboard, 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 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 saving, 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 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.

• The mats need to be cut only with a very sharp knife, otherwise the cuts will turn out uneven and when installing insulation between the posts, 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 the optimal material for his 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 - 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.

Thermal insulation is an essential component of any construction. Currently, materials from this category are presented on the market in a very diverse assortment, so it can be difficult for the buyer to make the right choice.

Among the variety presented, ISOVER brand insulation is consistently popular. This trademark the world-famous concern "Saint-Gobain", which supplies its products to the domestic market more than 20 years. During this time, a certain opinion has already formed about the Isover insulation. Therefore, we suggest that you familiarize yourself with the features and characteristics of this material.

Manufacturing technology "Izover"

What is ISOVER? This is mineral wool-based insulation, which is available in rolls, slabs and soft mats. However, regardless of the shape, the products are manufactured using the same technology. The process looks like this:

The raw material used is a mixture of quartz sand, limestone, soda ash, and microscopic glass particles.

The components are mixed and heated to temperature 1 300 degrees. As a result of thermal exposure, solid components melt, turning into a viscous homogeneous mass.

The resulting composition is loaded into a special installation (centrifuge), the bowl of which rotates at enormous speed. The walls of the working container have holes through which the molten substance is squeezed out, forming thin threads.

Then the resulting glass fiber is mixed with adhesive based on polymer materials.

The mixture is repeatedly subjected to heat treatment, simultaneously leveling the layers with steel shafts.

At the final stage of production, the insulation is cut into strips, following the specified dimensions.

Types of thermal insulation

The ISOVER insulation line includes several items. Each type of produced material has its own characteristics, which determines the scope of application. In particular, the following categories of insulation can be found on the market:

Basic characteristics can be found out from the markings indicated on the packaging. It looks like this:

OL-E. The only material in the series that is used for outdoor use. The material has high density and non-porous structure.

KL. Soft slabs designed for insulation internal partitions and ventilated facades.

AL. Insulation with this marking has a layer of aluminum foil on the surface that serves as a vapor barrier.

KT. This is a roll insulation used to insulate large areas.

Knowing these features, you can easily select insulation to solve specific construction problems.

Scope of application of fiberglass products

“Isover” is considered a universal insulation material, therefore it is suitable for the following work:

Heat and sound insulation of external wall structures.

Arrangement of ventilated facades.

Soundproofing of internal wall partitions.

Industrial ventilation systems, pipelines.

Pros and cons of insulation that you should remember

Like any building material, ISOVER has its advantages and disadvantages. By the way, the advantages of insulation are noticeably greater, which largely determines its steadily growing popularity.

TO strengths relate:

Wide range of products.

Easy to store and transport.

Long service life – up to 50 years.

Resistance to temperature changes.

Reliable heat and sound insulation.

Obvious shortcomings are considered:

Lack of environmental safety.

Dependence on external factors: perfectly absorbs moisture.

Some builders consider the soft structure of the insulation to be a disadvantage, which somewhat limits its scope of application.

Material Specifications

With an optimal price/quality ratio, thermal insulation has the following technical characteristics:

High thermal conductivity: 0.033-0.037 W/mK.

Flammability class NG: does not ignite and does not support combustion.

Wide operating temperature range: withstands temperatures up to 6,000 degrees.

Density: about 15 kg/m2.

Moisture absorption: 0.08 kg/m per day.

It should be clarified that these are average indicators. Insulation is available in a wide range, so density and thermal conductivity may vary.

Which is better, Isover or Rockwool?

These brands of insulation are direct competitors in the construction market, so consumers are interested in which material to choose. It is immediately necessary to clarify that both insulation materials have similar characteristics, however, are produced using different technologies.

ISOVER is a mineral wool made from glass fiber, produced by a French company. ROCKWOOL is basalt wool produced in Poland. Considering that the second insulation is made on the basis of basalt rocks, the production technology completely eliminates the presence of glass. Therefore, Polish products are considered more environmentally friendly.

If we talk about which insulation is better, there is no clear answer: it all depends on the area of ​​application. In particular, “Izover” is better suited for insulating the floors of the first floors, non-residential roofs, balconies and loggias.

This is due to the fact that non-compliance with installation technology can lead to microscopic particles of glass floating in the air of residential premises, which can have a detrimental effect on health. “Rockwool” does not suffer from such a “disease”, therefore it is optimally suited for interfloor and internal wall partitions.

Do not forget that ISOVER is much cheaper, which for many is a decisive factor when choosing insulation.

Subtleties of working with ISOVER insulation

When working with the material, personal protective equipment should not be neglected. Gloves and respirator are prerequisite during installation.

Directly laying the insulation is not difficult. The wall is cleaned of dirt and covered with a waterproofing film. Then a sheathing of wooden blocks or aluminum profile. Insulation fills the space between the bars, on top there is a layer of vapor barrier and finishing.

Briefly about the manufacturer

As mentioned above, ISOVER is a trademark of the Saint-Gobain group of industrial companies. The company has 350 year history, the central office is in Paris. The company has representative offices in 67 countries. In addition to ISOVER, Saint-Gobain produces insulation products of the ISOROC and ISITEC brands.

On the territory of Russia, enterprises are located in Yegoryevsk and Chelyabinsk near Moscow. Products are manufactured according to original technology, subject to mandatory certification international standard, complies with GOST standards. It should be noted that since 2013, the enterprises launched a production line for the production of basalt wool under the brand of the same name.

Izover insulation: technical characteristics, photos, price

You can easily get lost in the trade names of building materials, especially when you deal with them from time to time. In addition, all the names are very often similar. This also applies to Izover insulation, which was originally produced and developed in France, and came to us about 25 years ago. It was first used in the mid-30s of the last century with light hand Saint Gobain company. As before, this is a material based on glass fiber and mineral fibers, but thanks to localized production, the price of the material is no longer European and the quality is quite good.

What is Izover

Izover insulation technical characteristics photo the price of which will be shown below can be supplied in a wide variety of forms and formats. It depends on where it is used. Only one thing remains unchanged - this is an insulation material based on mineral fibers and fiberglass. The first quality of any insulation should be a minimum thermal conductivity coefficient. The tables indicate the characteristics of several types of material and the maximum thermal conductivity coefficient of the universal Isover. It is about 0.036 W/m³ and can vary depending on the density of the material.

The material itself is a fiber structure. The length of the fibers can be from 120 microns, and the thickness is no more than 4 microns. It is these indicators that guarantee the material high strength with minimal thermal conductivity and a sufficient volume of air retained inside the material. The production technology is patented and no other material simply physically can have the characteristics that Izover of any type declares.

Characteristics of Izover

Minimal heat loss is ensured by the simple property of air placed in closed space between the fibers of the material, this is what makes the material so warm. In addition, Izover can also be used as a sound insulator and the company declares it to be absolutely safe for health. It can be used not only for external insulation of facades, but also for internal insulation of rooms in a residential building, including children's rooms.

The vapor permeability of the material is also of great importance, since the accumulation of moisture in the structure of the material leads to a loss of thermal properties. However, when insulating foundations, plinths and facades with Izover, experts recommend leaving at least 2 cm for sufficient ventilation. To make it water-repellent, the material is impregnated with water-repellent agents, which guarantee the absence of not only moisture, but also biological threats. Therefore, the manufacturer can guarantee a 50-year service life of the material.

Safety, weight and price

According to GOST, Izover is considered non-flammable when used in the form of clean slabs, mats and rolls. In combination with aluminum foil or film, it can be considered low-flammable, but this is enough from a safety point of view to safely insulate internal walls with the material residential buildings, not to mention the facades. Isover in this sense has no restrictions on its use.

One of the distinctive qualities of the material is its very light weight. This is important when you consider the costs of lathing equipment, fastening materials and additional elements which are used during installation. Also, the low weight of the insulating structure reduces the load on the floors, walls or roof. The price of the material is also quite reasonable. With a high level of localization of production, it was possible to achieve the price level of domestic materials, which is about 130-180 rubles per square meter of insulation. Packaging an insulator can cost from a thousand to 1,500 rubles, depending on the brand.

Dimensions, density and types of insulation

The density of the material may vary decisive role when used under certain conditions. For example, the densest insulation has a density of 120 to 160 kg/m³ and is used for roofing, and the least dense with an indicator of 28-38 kg/m³ can be used for both walls and facades. Isover for flooring has a density of 150-165 kg/m³.

The dimensions of the material and the form of release can be very different, depending on the scope of application. For example, for foiled moisture-resistant Izover for wet rooms, it can be produced in rolls with a thickness of 50 to 100 mm, and the length of the loose roll will be within 1.25 m. Universal insulation can have a thickness of up to 100 mm and is available in the form of slabs of various sizes, at the same time, the material is perfectly cut and processed, and the size of the slab is selected based on the size and surface area in order to avoid a large amount of waste.

Areas of application of insulation

Considering the universal properties, low price and various forms of release, the use of the material can be very versatile. For example, the main areas of use of Izover are:

1. Foil-coated isover is used for baths and saunas.
2. Ceilings and floors are insulated with less dense material.
3. High-density Izover is used for floors and roofs.
4. It is used when installing plastic windows.
5. For insulation of balconies.
6. For insulation of basements and basements.
7. Interior partitions are insulated taking into account the fact that the material has good sound insulation.
8. For insulating facades.

Reliable and durable material (the manufacturer declares a 50-year warranty) can be an excellent insulation not only for a private home, but also for an apartment, as well as for non-residential buildings. Good luck with your choice and warm homes!

What you need to know about Izover insulation. Characteristics

The Isover brand, known in the world since 1937, has been selling its products in Russia and the CIS for several decades. Thermal insulation Izover consists of mats, slabs and rolls of stone wool and glass wool. Today we will look at their features.

Let's take a quick look at the history and facts

The Isover brand is owned by the French company Saint-Gobain, headquartered in Paris. The company was founded back in 1665 by order of French king Louis XIV. By the way, it is noteworthy that at that time the company was engaged in the production of mirrors and glass. And the brand name “Isover” uses two words “insulation” and “glass”. Today in Russia the brand has two factories where insulation materials are produced. One makes materials from stone fiber, the other from fiberglass. Isover thermal insulation in Russia was previously sold under the name “Uteplyaev”.

Purpose

In its line, the manufacturer has several dozen types of materials intended for insulation and sound insulation:

· And other objects.

The areas of application of these materials are shown schematically below.

General characteristics of “Isover” thermal insulation

It is perhaps difficult to pay attention to each area in the line within the framework of one article, so we will summarize the approximate general characteristics of these materials.

Main characteristics of Izover insulation:

• Thermal conductivity: 0.031-0.041 W/m2*K,
• Flammability: from G1 (low-flammable) to NG (non-flammable),
• Vapor permeability: 0.50 - 0.55 mg/mchPa,
• Service life: up to 50 years,
• Air permeability is 120*10-6m3/m×s×Pa,
• Thickness: from 50 millimeters.

These are only average indicators; you should always go to the manufacturer’s official website for the most accurate indicators. Below in the table we provide, as an example, more precise characteristics of lightweight insulation.

For information, we also provide a table of characteristics of Isover mats Classic

Stone wool

Izover mineral wool (basalt wool) is produced at a plant in Chelyabinsk, and is produced only in the form of a slab with different rigidity indicators.

Mineral wool Isover includes the following products in the line:

A little later we will describe the features of each representative of this line. Naturally, Izover mineral wool is more expensive than fiberglass materials.

The size of the slab is, as always, the same: 1200 by 600 mm. The thickness varies and is shown in the size chart below.

Glass wool

Cheaper and more often used Izover glass wool is represented in the product line:

· Izover Classic (classic Izover),

· Quiet and warm roof,

· Uteplyaev (Universal, only for Siberia).

Let's pay attention to three popular types of materials:

Description of materials. Both of the first materials are soft rolled fiberglass mats. However, the numbers in the index classify Isover KT 37 to the corresponding thermal insulation class 37, and Isover KT 40 provides Twin insulation - two mats are laid on top of each other. The total thickness is 50 and 75 mm.

The thermal conductivity of Izover KT 37 and 40 is corresponding - 0.037 and 0.040 0.040 W/m K. The width of the rolls in both cases is the same 1220 mm. For both, you need to build a sheathing and use materials for internal insulation walls and other interior works. Density is about 15 kg per cubic meter. Sometimes you can also find the marking Isover KT Special (KT Special) - this is insulation in rolls of the same series. Below are the details in more detail.

Insulation Izover 37 and 40 technical characteristics and dimensions:

Isover KL 37 material in the form of mats (soft Isover boards have a density of 16 kg/m3). This series is intended for insulation:

In those places where there will be no load on the insulation (that is, in the frame and along the joists).

Below in the table you can see the characteristics of Isover kl 37

Model KL 34 has lower thermal conductivity than the 37th.

There are separate types of foil material for saunas. One side of the mat is covered with foil, which prevents it from getting wet.

The density and dimensions of Izover correspond to GOST standards. The declared parameters of Izover insulation and technical characteristics correspond to the market as a whole.

The cost of insulation, especially during a crisis, is a particularly important topic. In this article we will not be able to provide prices for all options, but we will still show the main ones.

For example, the “Sauna” model in a roll 6250 long, 1200 wide and 100 mm thick will cost approximately 1400 rubles.

Isover KL 37, 10 slabs per package, 100 mm thick slabs will also cost about 1,400 rubles.

A pitched roof, 20 slabs, each 100 mm thick, will cost 1,000 rubles.

Here is a screenshot of the cost from a popular online store.

What do those who have already used Isover insulation say? Let's read their opinions:

We insulated the walls of the house stone wool Rockwool and worked without glasses or gloves. It remains to insulate one wall and there weren’t enough slabs. We decided to save money; the price for 8 slabs of 50 mm thickness was 350 rubles. Save 20 rubles on each stove when purchasing Izover. While my husband was at work, I set about installing the insulation myself. I didn’t wear any protective equipment, as before, it was tough. I cough, sneeze, itch. Covered it with film and screwed the drywall down. Even after two days the insulation still stinks. I also covered everything on top with expensive photo wallpaper... it’s a pity to take it off. But there is no choice left, when you sleep, you feel like you are breathing dust. The small child did not sleep for three nights. We took out this insulation and ordered a new one. It’s a pity, of course, for the money, I was once again convinced that it’s better to be more expensive, but just once. Hope it helps someone. Insulating the walls with Izover inside seems to me not an option at all.

It is worth remembering that Izover emits harmful substances - phenol (it stinks). The higher

the temperature in the room, the stronger the smell and the more substances released. It is recommended to cover the cotton wool with film on top and bottom. As my repair experience has shown, it is imperative to place it under the cotton wool, from the ceiling side. It is advisable to secure it well with a stapler. Don't forget to tape the joints - this will reduce the smell in the room. (Even if you don’t feel it yourself, the evaporation is still there).

I work as an engineer and I have to select materials that are both inexpensive and effective. I decided to use Izover for the pipeline.

For as long as I can remember, pipes have always been insulated with green wool. It is very prickly and has almost no effect - people’s pipes are still cold. We decided to do something about it. I found Isover and was attracted by the low price. They wrapped the pipe, plastered it over the mesh and left it for testing over the winter. The pipes lie on the surface, so you should be able to see how the insulation works.

So, it snowed, it was +115 inside the pipe, if there had also been a plus on the plaster, a snow crust would have formed, but no, everything is fine, the pipe on top is cold.

I calculated the costs and it turned out that taking into account all the rules, the price would be 2 times lower compared to other materials.

After that, the entire enterprise switched to Izover thermal insulation, and now we have insulated not only pipes, but also walls, roofs, facades, especially ventilated ones.

The material performed well and did not deteriorate over time. A vapor barrier is required when installing on facades and roofs. It cuts quite well with a regular knife.

This article presented the characteristics of Izover. We also included reviews from real consumers for an objective assessment. Conducting thermal insulation work, for example, wall insulation, you will have something to take into account regarding this brand of insulation.

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.

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:

1. Izover- This is a thermal insulation material, so it is characterized by low thermal conductivity - 0.038.
2. Excellent sound insulation performance.
3. 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.
4. High moisture permeability. This indicator is a disadvantage. This is explained by the fact that the material has a porous structure.
5. Low specific gravity– 13 kg/m3. This simplifies the process of installation, transportation and loading of material. Installation of insulation can be done with your own hands.
6. Ecological cleanliness.
7. High degree of durability from the negative effects of chemicals.
8. High ductility. Mats can be compressed up to 60%, and rolls up to 75%.
9. Fire resistance.

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 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.

Izover insulation and its technical characteristics
Isover insulation: technical characteristics. Isover insulation dimensions. Popular brands of insulation and their cost.

“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. Technological progress and competition in the ranks of manufacturers have contributed to the fact that today the problem of choice has become more pressing than the problem of where to find money for a purchase. To confirm these words, one can cite the fact that such material as isover has appeared on the modern market.

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 that was similar in characteristics to the stone wool widely used at that time 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 by isolating 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;
• For flat and sloping roofs;
• For floors and ventilated facades and much, much more.

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.

“Isover” is an insulation material whose technical characteristics allow us to judge it as one of the most effective materials today. It has a very wide scope of application. It is made from fiberglass and comes in the form of easy-to-install slabs and mats. It is used both for insulating small private houses and high-rise buildings or industrial buildings. Also, this type of insulation is very well suited for protecting water pipes and other household communication systems from cold.

How it is made

So, what is Isover insulation? The characteristics of any person depend primarily on how accurately they are observed required technologies in the process of its production. Isover insulation is manufactured as follows:

• Cullet, limestone, and other minerals are thoroughly mixed in advance.
• The resulting mixture melts at a temperature of 1300 degrees. until a homogeneous fluid plastic mass is obtained.
• In a special installation, this liquid glass is fed from a great height into a bowl rotating at high speed, the walls of which have small holes. Under the influence of centrifugal force, the hot mass is squeezed out in the form of long thin threads.
• The fibers are mixed with yellow polymer glue.
• The resulting sticky mass is fed into a special oven, where it is rolled between steel shafts and blown with hot air. As a result, the glue sets and the layer itself is leveled.
• The finished glass wool is fed into circulation saws to be cut into slabs of the required size.

Advantages of the material

The advantages of Izover insulation (the characteristics of which will be discussed below) include primarily:

• ease of installation;
• low degree of thermal conductivity;
• high degree of fire resistance;
• versatility;
• light weight;
• excellent soundproofing qualities;
• low cost.

Disadvantages of insulation

Of course, like any other building material, Isover slabs also have certain disadvantages. These include:

• questionable environmental safety;
• the need to use special clothing during installation.

All fibrous materials, including Isover (whose characteristics are otherwise very good), absorb water well, which is why they lose a significant part of their heat-preserving qualities.

Scope of application

• wall insulation;
• heat and sound insulation of internal partitions;
• stone and wooden houses in an insulating pie;
• interior wall cladding;
• insulation of floors both above and below;
• roof insulation in houses with residential attics and attics;
• windings of communication pipes.

Foundations are usually insulated with expanded polystyrene. When using Izover for this purpose, it is necessary to additionally provide very high-quality waterproofing.

"Izover": characteristics

Of course, before choosing this material for insulating a house, you should find out what specific properties it has. There are several types of Isover insulator. In terms of characteristics, they all differ slightly. Materials of this brand are produced with different density and thermal conductivity.

Isover Classic insulation, for example, has the following characteristics:

This variety Isover insulation is currently the most popular. Other types of insulators of this brand also have good qualities.

"Isover" is supplied, the characteristics of which, therefore, make it possible to judge it as actually effective insulation, in easy-to-install slabs and mats.

Installation features

The frame for “Izover” can be assembled from both wooden planks and metal profile. The distance between the individual elements of the sheathing should be slightly less than the width of the insulation boards. This allows you to install them by surprise.

Of course, “Izover”, the technical characteristics of which we have described, when used as a heat or sound insulator, must be protected from moisture. In order to prevent it from getting wet, steam and waterproofing films are used. When assembling a pie of walls or roofing, in this case a certain order of installation of materials is observed. The vapor barrier is installed on the interior side. Due to temperature differences, the humidity in rooms and attics is usually higher than outside. Therefore, condensation forms on the walls and ceiling. Using a vapor barrier prevents it from getting on the insulation. Mounted outside. It protects Izover from getting wet during rain or melting snow.

Additional fasteners when installing slabs, as already mentioned, are not used. They are only necessary when installing the material on the ceiling. In order to completely prevent their loss, in this case special dowels called “fungi” are used.

Since the material is capable, albeit in small quantities, of releasing substances harmful to human health, when installing it from inside the premises, you should carefully monitor the tightness of all finishing seams.

Varieties

“Isover” - insulation, the technical characteristics of which we discussed above - is classified into several popular types. In private housing construction, as already mentioned, the “Classic” material, marked with the letter “K,” is most often used. It, in turn, is divided into:

• "Isover KL 34" are very soft boards with high thermal insulation properties, used for insulating surfaces without loads.
• "Isover KL 35" is a material with a slightly higher density. It is usually used for the same purposes as variety 34, that is, for walls and partitions.
• "Isover 37" is most often used for insulating floors, roofs and ceilings.
• "Isover KT" is usually used for insulating basements or attics.

The type “Isover Classic Plus” is also very popular. Its characteristics are exactly the same as those of the regular “Classic”. These two varieties differ only in thickness. “Classic”, as can be seen from the table, is supplied in 50 mm mats. For “Classic Plus” this figure is 100 mm. There are other varieties of Isover material designed for a variety of purposes (Isover RKL, Isover OL, etc.).

Conclusion

Thus, the Izover insulation, the technical characteristics of which were discussed in detail in this article, is a very warm and high-quality material. You can protect your home from the cold using it as effectively as possible. This, as well as its not too high cost, explains its extraordinary popularity among both private owners and small and large developers.

There are a large number of thermal insulation materials on the market. Existing types of insulation are improved every year, gaining new, useful properties. At the same time, there are also materials that remain unchanged in their parameters, but at the same time occupy leading positions in the rating, for example, Izover insulation. The technical characteristics of this material provide high-quality thermal insulation.

Key insulation indicators

Isover - insulation, which is made from fiberglass itself best quality using special technology. It is in many ways similar in its properties to mineral wool. Available in:

• rigid and semi-rigid slabs;
• rolls and mats.

The latter are used in the arrangement of building facades, ceilings and for roof insulation. The basis for Izover is glass fibers. Their indicators:

• length varies from 100 to 150 microns;
• thickness is 4 to 5 microns.

Due to the above parameters, the insulation is characterized by resistance to various types of loads and elasticity.

Thermal conductivity indicators

Coefficient of thermal conductivity is not so large and is only 0.041 watts per meter per Kelvin. Moreover, this value does not change upward over time, as happens with some other heat insulators. Thus, glass fibers are able to conserve heat and retain air.

Sound insulation parameters

Fiberglass material has good performance in terms of protection from external noise. This is due to the fact that there is an air gap between the layers of material. She is the one responsible for the delay extraneous sounds. Silence in the room where Izover was applied was ensured.

Prone to fire

Any thermal insulation materials, the density of which reaches 30 kg per cubic meter and are called Izover, classified as non-flammable. This is their definition, in accordance with GOST standards. This insulation can be used in any home, including residential ones. Izover's characteristics allow this to be done. Its use is considered safe both for insulating a one-story cottage and a high-rise building.

Rigid and semi-rigid modifications, equipped with a coating of Tyvek film, fiberglass or aluminum foil, are considered low-flammable. There are some restrictions for such insulation, but there are relatively few of them. Accordingly, they can be used almost everywhere. The main requirement concerns strict compliance with fire safety standards in the building, which form the basis of SNiP.

Vapor permeability of Izover

For most modern thermal insulators, resistance to moisture is the main disadvantage. Most of them cope with their functions, as long as the air in the room is dry. Once it gets wet, even fiberglass can retain heat less well. But Izover is good because he is capable how to quickly absorb moisture and quickly give it back.

For this rule to always work and under any conditions, it is necessary to leave a gap between the insulation and the wall, the diameter of which would be at least 2 cm. It is necessary for optimal ventilation. If you forget about this point, then the thermal insulation characteristics of Izover will begin to decrease as moisture accumulates. Its vapor permeability varies from 0.50 to 0.55 mg/mchPa. If the insulation receives 1% moisture, then the thermal insulation performance will drop by 10%.

Duration of service

Isover is an insulation material for which service life is one of the key indicators. Even if it is able to retain heat for a long time, then can last no more than a year. It all depends on the specific product. Insulating a building requires a lot of effort and time. Yes, and this requires a lot of work.

Fortunately, Izover is an exception to the rule. By using it to cover the floor and walls, you can forget for a long time about the need to re-install it. There are examples when it was possible to use a heat insulator for several decades in such a way that all its indicators remained unchanged.

The so-called water repellents included in Izover have water-repellent properties. In addition, insects and other pests do not settle in this insulation, since they simply do not like such a habitat. Even mold does not attack fiberglass insulation.

Environmental performance and safety

Izover can boast not only of its technical characteristics. Any fiberglass materials of this type are considered harmful to human health. It does not include any toxic compounds. Finnish scientists spent a long time checking the parameters of the material and came to the conclusion that its use, even over a long period of time, does not negatively affect people’s quality of life.

Product weight

Isover is much lighter than other heat insulators. That is why in those structures where the walls are not made of the most durable materials or the excessive load is unacceptable, it becomes a way out.

Release form

For maximum convenience insulation is produced in 2 different modifications. These are slabs of varying hardness, mats and rolls that have different thicknesses. Let’s say that if the heat insulator is single-layer, then the indicated indicator varies from 5 to 10 cm. For a two-layer one, it is no more than 5 cm. Most often, slabs are produced meter by meter, occasionally there are other dimensions. One roll covers from 16 to 20 square meters. The standard roll length is 1.2 m, while its length can vary from 7 to 14 m.

After unpacking Izover in pressed rolls, it straightens on its own. To do this, it is enough to remove the packaging shell.

Other characteristics

Other important indicators include:

• density, which is 13 kg per cubic meter;
• the density of the connection to the base, which is at a fairly low level and decreases, in accordance with the characteristics of the object being insulated;
• air permeability equal to 120*10−6m3/mxsxPa.

Many characteristics are determined by what type of material is used and what its purpose is.

Scope of application and classification

Isovers can be used for various purposes.. This includes the construction of various structures and finishing - internal and external. You can insulate the floor with this material if there is a breeze underneath it from the basement. You can use it to cover walls for insulation, for example, in an attic or attic. It is also suitable for protecting walls from cold winds. This type of insulation is relatively inexpensive.

This material is available in several varieties. Each of them is suitable for performing certain types of work.

KL34 and KL37

slabs with a thickness of 5 to 10 cm. The use of additional fasteners for installation is not required. These boards can be used to insulate ventilated facades and masonry in which there are several layers. You can take almost any plane for insulation. They can be either horizontal or not vertical. It is also possible to use those that are located at an angle.

It is supplied in pressed packages. It does not require fastening elements during installation. This material is used for arranging floors between floors, protecting walls and roof slopes. It is important that the isover must fit tightly to the working planes.

KL37 is available in pressed rolls. No fastening elements are expected here. But as in the previous case, the structure of the two materials must be in close contact with each other. This modification is used for thermal insulation of attics and roofs, interfloor ceilings. It is suitable for indoor partitions and work walls.

KT40 and STYROFOAM 300A

The first option is material consisting of two layers, each of which differs in thickness of 5 cm. It looks like tight rolls. Used to insulate surfaces without additional fasteners. It is used on ceilings and floors. If the cavity to be filled with insulation is not deep enough, you can divide the material into 2 layers.

STYROFOAM 300A, on the contrary, requires the mandatory use of fasteners. It is produced in the form of a rough material, the surface of which provides good adhesion to concrete. The insulation contains extruded polystyrene foam. Thanks to it, isolated cells are formed. In turn, due to this, resistance to cold weather and the effects of fire is guaranteed. The heat insulator is suitable for working with vertical and horizontal surfaces. It is used to insulate internal and external walls, flat roofs and floors. Plaster can be applied on top.

VENTITERM and its properties

Considered a universal insulation. Its technical characteristics are such that you can either use fasteners or do without them. Available in a form that is treated with a water repellent. It is based on mineral wool, which contains basalt fibers. This material is used for one-sided insulation of ventilated facades, water supply and ventilation pipes. It is also suitable for protecting precision instruments from cold.

For pitched roofs and ventilated facades

Izover, designed for pitched roofs, is used for thermal insulation of the roof. It is produced in the form of plates. Their dimensions are 61 cm in width and 10 by 5 cm in thickness. This material does not tend to absorb moisture. Also characteristic is a high level of sound absorption. The next useful properties of the material are non-flammability and vapor permeability. Isover for pitched roofs retains heat, especially if two layers are used. The top layers cover the joints on the bottom. When installing on rafters, it must be arranged in such a way that the insulation boards do not fall through.

The modification intended for a ventilated facade is in many ways similar to ordinary looking Izovera. It is produced in a two-layer version, due to which it retains heat perfectly. During installation, do not allow the material to lag behind the surface.

Sound protection model

A special modification is available in the form of slabs and mats. Better than other models, it is able to protect the room from sounds penetrating from the outside. Used for insulating internal partitions and suspended ceilings.

Precautions at work

In accordance with safety precautions, the use of fiberglass materials requires the mandatory use of safety glasses, gauze and gloves. We must definitely remember this. It is also important to use clothing with long sleeve, trousers and socks. This rule is difficult to follow in the hot season. But people who stick Izover slabs on, exposing their torso, greatly regret it in the future. At first it seems that the work is easy, but then the body begins to burn and itch. Even a shower in this case turns out to be useless. That's why you shouldn't ignore the above rule.

When working with this material, you need to stand in such a way that the bright rays of the sun fall on it . This will allow you to see clouds of smoke that come from him. This is fine glass dust. After installation, the insulation will not pose a danger, but during repair work it is advisable to use protective equipment. Proof of the safety of the material is the fact that Izover is even used by wasps to build nests. Yes, and mice sometimes gnaw holes in it.

To protect other living rooms from glass dust that is formed during installation, it is necessary to lay a wall covering film between Izover and the lining. It could be Utahvek. And even if the lining gradually crumbles, the sprayed particles will not pose a threat to you. Although if you compare Izover with glass wool domestic production, which is not afraid of any protective barriers, then the first will clearly win in all respects. And rodents don’t really like glass wool, unlike Izover. This also says a lot.
