Izover is optimal. Izover insulation: technical characteristics, types, advantages and disadvantages. Isover mineral wool for specific applications

The basalt heat-insulating plate of the "Optimal 50" series, as it deservedly received such a name. This is really the best option for solving most problems with the insulation of various buildings, structures and their individual elements.

This insulation balances between good insulation efficiency and the comparative cheapness of the material itself (the Ventfasad series also has similar characteristics).

Heat insulator "Isover Optimal

And for those buyers who find the scope of the Optimal 50 series too narrow, the manufacturer has provided a modified and more efficient version called Izover Ruf N Optimal 50. However, it was the classic Izover Optimal insulation that gained immense popularity.

1 Thermal insulation Optimal

This insulation is delivered as an ordinary lightweight thermal insulation board, in which the main component is mineral basalt wool. The advantage of this insulation composition is that basalt wool does not burn, which means that this insulation can be safely used in wooden buildings.

Insulation "Optimal 50" is made for use in enclosing structures, in which the heat-insulating plate will not be subjected to heavy loads. In addition, "Optimal 50" can also be used as an unloaded autonomous sound insulation.

At the same time, the range of application of the product is huge, it can be used on horizontal-vertical inclined buildings of any type, including buildings with a small number of floors, and in cottage construction (individual buildings).

In general, this thermal insulation board can be successfully used in the following structures:

• In the floors along the lags;
• In suspended modern ceilings;
• In the creation of insulation of the interfloor overlap;
• For pitched roofs and attic;
• In the insulation of frame walls;
• For heat and sound insulation of interior partitions.

Insulation of walls from the inside "Isover Optimal"

The scope of the "Optimal" series is almost identical to the "Ventfasad" series.

1.1 Features and benefits

A series of heaters "Optimal" has impressive properties and has quite serious technical characteristics:

• The density of the product, like the Ventfasad series, is -28 - 37 kilograms per square meter;
• The thermal conductivity for the parameter λ10 is 0.036, for the parameter λ25 - 0.038, for the parameter λA - 0.039, for the parameter λB - 0.040;
• The compressibility (potential) of the material does not exceed 25%;
• The parapermeability is not less than 0.30 milligram/m*Pa;
• Water absorption is no more than 1% as in;
• The flammability group to which the Optimal series belongs is NG.

The good technical characteristics of this product are perfectly combined with the undeniable advantages and features of the Optimal series, among which it is worth noting such as:

• Really wide area of ​​possible application (as in the series "Ventfasad");
• Quick, easy and affordable DIY installation;
• The material does not sag in its design during its entire potential service life;
• The material compensates for possible unevenness of the surface on which it is used;
• As well as the Ventfasad series, the Optimal series does not need additional fasteners and clamps;
• The density of the insulation is high enough so that the material does not undergo deformation during the service life;
• Izover "Optimal" easily provides more than a high level of so-called thermal protection due to the relatively low coefficient of thermal conductivity property;
• The insulation of this series has a high moisture resistance;
• Doesn't burn at all

isover. Which insulation is better: in slabs or in rolls?

In this video you will find out which insulation is easier to work with: in slabs or in rolls. The main characteristic showing the quality of the insulation material is its recoverability. High-quality material has the ability to recover to the stated dimensions after opening the package, which was demonstrated in the video. The thickness of Isover insulation, both in slabs and in rolls, after opening the package, recovered to 50 mm. To install the insulation in the slabs, it is necessary to measure the distance between the racks of the frame. The slabs are ideal for wall insulation with a standard distance between frame posts of 600 mm. When installing the plates, joints are formed, which must be covered with a second layer of plates. Insulation in rolls is best used with a non-standard step between the racks of the frame. First, the distance between the posts is measured, then the unpacked roll is cut to the required size and rolled along the entire length of the wall. When insulated with rolls, joints are not formed. All Isover materials are highly resilient and securely held in place.

Isover: How safe are thermal insulation materials?

In this video, you will learn how safe the use of mineral wool is for your health and the health of your family. The safety of mineral wool is confirmed by eco-labels, as well as studies in major research centers, such as, for example, the Institute of Hygiene. Sysina. In addition to these guarantees, Isover provides an environmental declaration for its products. Thermal insulation based on mineral wool is used in all buildings and structures, including kindergartens, schools, hospitals. Another sign of the absolute safety of mineral wool is its incombustibility and fire safety, which is confirmed by certificates of compliance with fire safety requirements.

Isover: Which thermal insulation is better: stone wool or fiberglass?

Isover is the only company in Russia that produces mineral wool based on fiberglass and stone wool. Rock wool insulation is based on molten rocks, and fiberglass insulation is based on sand and cullet melted at 1000 °C. Stone fiber materials are denser than glass fiber materials, which is primarily due to the length of the fibers in the production of the base for the insulation. But density is not a determining parameter when choosing a heater. The main characteristics are thermal conductivity and mechanical characteristics. If we compare materials by application, insulation based on both types of mineral wool is divided into three types: Light grades are used in frame structures, for insulating walls, and pitched roofs. Such a heater does not take on any load. Rigid grades are used in plaster facades, flat loaded roofs. Highly specialized materials are used for soundproofing partitions and for insulating saunas and baths. Fiberglass-based materials are lighter than stone wool-based materials. Due to the length of the fibers, they have greater elasticity, which allows filling all the irregularities and voids of the insulated surface, eliminates the formation of "cold bridges" and provides reliable fixation in the structure. Both types of materials are non-combustible materials, do not propagate and do not support combustion. Now that you know the differences between the two types of mineral wool, you will make the right and objective choice of thermal insulation material for your home.

Isover: Is the density of thermal insulation materials important?

Is the density of mineral wool insulation a decisive characteristic when choosing a heater? You will find the answer to this question in this video. The density of the heat-insulating material affects the coefficient of thermal conductivity, strength characteristics and other parameters. But this relationship is not linear. The dependence of the thermal conductivity coefficient on the density of the material is the same for fiberglass and stone wool. For fiberglass-based insulation, the optimal density range, which provides the minimum thermal conductivity coefficient, is 25-35 kg / m3. For insulation based on stone wool - 45-55 kg / m3. Thus, stone wool is able to provide the same thermal insulation characteristics, but at higher densities. Remember that when purchasing heat-insulating materials, we acquire the heat-insulating qualities of the product, and not its density. Even a light fiberglass heat-insulating board with a density of 60 kg/m3 is able to withstand a large load without deformation. Therefore, when choosing a heater, first of all, pay attention to the coefficient of thermal conductivity, durability, incombustibility and environmental friendliness.

In our time, the building materials market has such a wide variety of insulation materials that it often even makes it difficult to choose. They differ in the base material and the form of manufacture, in the field of application and, of course, in the reputation of the manufacturer. The cost of heaters is often very considerable, so the desire of consumers to give their money for a guaranteed quality product is quite understandable. And this means that it is best to stop the choice on the original products of well-known brands, among which "Isover" (in Russian transcription - "izover") takes one of the leading places in terms of the effectiveness of thermal and sound insulation of buildings, 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 there is no doubt about their high quality.

The Isover manufacturer is a company that is part of the largest international association Saint Gobain, which manufactures a huge and comprehensive range of modern building materials. "Saint Gobain" brings together more than a hundred industrial companies and organizations involved in innovative developments in the construction industry. It's hard to even imagine, but the history of the appearance of this manufacturer dates back to the 17th century - how many companies in the world would have already celebrated their 350th anniversary?!

Huge, centuries-old experience, the ability to properly organize the activities of all links, 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 manufacture of materials that allow you to create zones of the most comfortable living space.

"Saint Gobain" works in various directions. These are high-tech materials, ordinary flat glass and glass designed for special applications, construction products, which include insulation, drywall and other gypsum-based products, building mixtures, tiles and facade cladding, acoustic panels for walls and ceilings, integrated drainage systems, plumbing and sewer pipes, and much more.

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

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

All enterprises of this association successfully pass the certification of the international standard of environmental management, therefore, heaters are considered environmentally friendly products. The company places its products in the same environmental group as linen and cotton, and they comply with European and international standards - EN 13162 - ISO 9001, as well as Saint Gobain's own extremely stringent standards.

The main types of thermal insulation "Isover"

So, the insulation materials of this manufacturer can be made from glass or basalt fibers. Such specific structures are obtained as a result of the processing of quartz sand, cullet or mineral rocks of the basalt group - their melting followed by drawing using the TEL fiberization technology. The resulting thinnest, almost microscopic threads with a thickness of 4 ÷ 5 microns and a length of 110 ÷ 150 microns are interconnected with special resins.

Mineral heaters "Isover" are produced in mats, which are then rolled up, and in slabs. Both of them can have different thicknesses and several linear dimensions, depending on their purpose and the recommended laying technology.

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

• "Isover Warm House Stove"
• "Isover Warm House"
• "Isover Warm Walls"
• "Isover Warm Roof"
• "Isover Sauna"

And the following types can be safely attributed to the materials of universal purpose:

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

Each of the above heaters 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 wall materials are divided into those used for interior surfaces and for building facades.

There is one more criterion for the division of insulation materials "Isover" - by rigidity. The designation has an alphabetic symbolism applied to the package, and its decoding 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 package, increase significantly in the thickness of the slab or mat).

Table of division of heaters "Isover" according to the degree of rigidity:

General advantages and disadvantages of Isover heaters

Before proceeding to a detailed review 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 you to keep the heat generated by the heating units 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 paying for it.
• A high level of absorption of sound waves - this quality will reliably protect the house from external noise, and the rooms (when using the material in the construction of partitions) - from extraneous internal sounds. Good is achieved due to the structure of the material, since the air gap between the fibers is able to absorb vibrations. Any, in fact, from Isover heaters 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 specifically for noise protection.
• A high level of vapor permeability is one of the most important qualities for a heater. Such material is also called "breathable", since it does not collect and does not retain moisture in its structure, which means that it will not create a favorable environment for the appearance of pathogenic microflora, the walls will not become damp. In addition, the ability to freely pass water vapor makes the insulation more durable in its direct functionality, since the waterlogged material has a sharp increase in thermal conductivity, and it becomes unable to provide proper thermal insulation of building structures.
• The incombustibility of Isover heat insulators makes them absolutely safe. The material is classified according to the NG combustibility scale, that is, according to the highest degree of resistance to fire, which means that it can be safely used in the construction of frame, block and log houses.
• "Isover" - slabs and mats are lightweight, so they can be used to insulate buildings in which excessive load on the supporting structures is unacceptable.
• The service life of the insulation, subject to the installation technology and operating rules, is 50 years or more.
• Isover heaters are treated with water repellents, that is, water-repellent compounds, so they have a fairly high moisture resistance.
• Affordable cost. Compared to other similar materials, Isover products have a price that is quite acceptable for a family with an average income.

True, the heat insulators of this manufacturer also have their own “minuses”, which for some may turn out to 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. Binder resins have not yet been eliminated - and although formaldehyde emission is indeed reduced to a possible minimum, it is too early to talk about its complete absence.

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

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

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

• The manufacturer calls the advantage of heaters their incombustibility. However, it should be noted that some types of insulation (this applies to foil to a greater extent) are not non-combustible, 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 observing the fire safety requirements prescribed in SNiP 21-01-97.

Characteristics of thermal insulation materials "Isover" and recommendations for their use

Now, having familiarized ourselves with the information about the main "pluses" and "minuses" of Isover thermal and sound insulators, we can proceed to consider the detailed technical characteristics of each of them.

Prices for insulation "Isover"

Isover insulation

Universal heaters "Isover"

The company produces not only narrow-purpose heaters, but also universal ones that can be used for different building structures. Such 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"

"Isover Optimal" is a universal material made from basalt fibers, which is used for insulation and soundproofing of all departments of the frame house structure, except for the foundation - this is the roof, ceilings, walls, partitions and floors along the logs.

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

- low thermal conductivity and excellent elasticity;

— simple installation that does not require additional fasteners;

— versatility of use;

• The first step is to install racks of timber with a step of 590 mm on the insulated surface or in the frame. Such a distance "in the light" will help the plates of heat and sound insulating material to securely fasten by surprise. The thickness of the timber racks or lag should be equal to the thickness of the heat insulator.

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

"Isover Pro"

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

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

• "Isover Profi" has one of the lowest thermal conductivity of all materials from this manufacturer.
• Due to the fact that special markings are applied to the mat, it is convenient to cut it. At the same time, even if a non-standard design 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 such material is easy and fast, since the roll on the package has the markings necessary for cutting. Therefore, the mats are cut to the desired width without unrolling the roll.

• The first step is to install racks with a standard step of 600 mm for the crate. The width of the roll 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 stacked between the lag by surprise.
• The cut roll is released from packaging, unrolled and installed between the frame elements. If the strip of insulation is not additionally cut into plates across, this will help to avoid the formation of cold bridges.
• The non-standard arrangement of the racks of the frame will complicate the 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 spreading on each side.
• If the attic structure is also insulated, then before installing the insulation, a windproof film is fixed on 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 floor of 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 plinth, foundation and surfaces that receive a high load. They are heat and sound insulated with frame structures - partitions and external walls, roofs and ceilings, ventilated facades and floors along logs.

"Isover Classic" is a fiberglass insulation produced in the form of mats in rolls and plates, 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, therefore it is not suitable for installation under a screed and for finishing walls with plaster. If it is planned to be used for facade insulation, then only for materials such as siding, lining or plates fixed on the crate.

"Isover Classic" has the following distinctive features:

• A layer of this insulation with a thickness of 50 mm is equivalent in terms of heat saving to brickwork with a thickness of 950 mm.
• Using "Isover Classic" as a home insulation, you can reduce the cost of heating the building by 40÷45%.
• The material performs two functions at once - protecting the house from the cold and external noise.
• Installation of plates is carried out without the use of additional fasteners - it is installed at a distance between the elements of the crate or lags, adjoins them tightly, excluding the occurrence of cold bridges.

• If the floor is insulated along the lags, then it is recommended to fix them on glassine pre-spread on the base.
• The width of the "Isover Classic" slabs is 610 mm, and the mats are 1220 mm, so the distance between the floor joists or the racks of the crate should be 600 mm.
• The roll is cut across in the packaged form in half. The manufacturer prudently applies markings on the packaging, which will be easy to navigate when cutting the material.
• Then, the insulation boards are laid, and the mats are rolled out between the wooden structural elements. Due to the fact that the heat insulator has a width greater than the distance between the lags by 10 mm, it will fit snugly between them.
• The insulation must fill all the space between the timber. Only in this case, it is possible to achieve the desired effect of keeping warm and protecting from outside noise.
• If the insulation is installed in two layers, then the mats of the second layer must be laid or installed with an offset of their joints by 120 ÷ 150 mm relative to the first.
• The material is recommended to be used in combination with a wind and hydroprotective film and a vapor barrier membrane.

"Isover Extra"

"Isover Extra" is a fiberglass insulation in the form of plates with increased elasticity with a 3D effect, which allows the material to straighten out after it is compressed, filling all the free space between the timber or metal profiles in drywall systems. In addition, the plates fit snugly against the wall when insulating vertical surfaces, and are also tightly connected to each other at the joints, which completely eliminates the appearance of cold bridges.

Thanks to these features, Isover Extra insulation is universal and is used for thermal insulation of walls from the inside of rooms, facade surfaces for cladding them with bricks, siding, clapboard and decorative plates, roofs of various modifications.

"Isover Extra" has a thermal conductivity coefficient of 0.034, which makes it one of the most effective materials from the heaters presented by "Isover" in terms of heat saving - 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 plates 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 surface to be insulated for the installation of Isover Extra - due to expansion, it will fit snugly against it.

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

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

"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 from the processing of a specially selected mixture of limestone, sand and soda. However, plates are more convenient to use for insulation in one area, and mats in another.

• "Isover Warm House Stove", as the name implies, it is produced in slabs, which are more convenient to use for thermal insulation of vertical surfaces, both from the inside and outside, as well as to insulate them

• "Isover Warm House" It is produced in the form of mats and goes on sale in rolls. This modification of the insulation is perfect for laying on horizontal surfaces. So, they isolate the interfloor ceilings, they will insulate the floors well above the cold basement, but they are mounted only between the logs, and this material is not suitable for screeding.

Having dealt with the universal insulation "Isover", you can proceed to consider those that are designed for specific areas of the structure.

Isover mineral wool for specific applications

For individual sections 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.

Facade insulation 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:

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

Prices for plaster "Facade-master"

facade master

• produced in glass fiber slabs and is an innovative material for thermal insulation of a 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, which will be applied to their surface in a thin layer.

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

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

Manufacturer's recommendations for installing insulation

• Work on the insulation of the facade using the "wet facade" technology, that is, with subsequent plastering, must be carried out at a temperature of at least +5 degrees, having previously protected the walls from possible direct ingress of water. Usually, a temporary structure made of timber or metal profiles is installed for this, which serves as a frame for a plastic film.
• Installation of insulation starts from the bottom of the wall. Fix the plates on a pre-primed and dried wall, on an adhesive solution. The solution must be applied to the surface of the slab so that contact is ensured over at least 40% of the total area of ​​the slab.

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

• After the glue dries, the insulation is additionally fixed on 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 plates can be seen through it. Usually the same glue is used as when installing the plates. After that, a thicker layer is applied, about 3 ÷ 5 mm, and it is recommended to walk over it with a notched trowel with a low comb.

• After that, without a pause, a reinforcing fiberglass mesh is fixed on the prepared surface, which is sunk into the distributed solution with a spatula (trowel). The mesh must be completely immersed in the solution.
• Next, proceed to the application of a thin (about 3 ÷ 4 mm) base plaster layer. This may be a special composition designed specifically for the “wet facade”, or again the same assembly adhesive for mineral wool. This layer is leveled, smoothed, and when ready, it is primed with a special compound for a specific type of decorative plaster.
• After the base plaster layer dries, decorative plaster can be applied on it.

Wall insulation materials inside and out

The next line of insulation "Isover" includes products designed for thermal and sound insulation of walls both from the inside and outside. These include universal materials such as "Isover Profi" and "Isover Classic Slab", 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:

"Isover Standard"

"Isover Standard" - these are plates made from basalt fibers, which are used in multilayer insulating structures in which a block house, siding, lining, facing brick, and other similar materials act as a decorative finish. In addition, Standard slabs are also suitable for thermal insulation of frame structures, as well as for attic and pitched roofs.

• The material has an average density, therefore it is not suitable for installation under plastering walls.
• The good elasticity of the insulation ensures its snug fit to the surfaces of the walls and the frame structure.
• Increased tensile and strength parameters provide reliable fixation of the plates with the help of special clamping fasteners - "fungi".

"Isover Warm Walls"

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

This version of the insulation is used for thermal insulation of walls from the inside of the building and for outdoor installation under sheathing with siding, decorative plates, 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.

• Insulation plates are sufficiently resilient and elastic, so they hold well between the racks of the frame, do not slip or break during installation.
• Increased moisture resistance allows the use of material for insulation of roofs and balconies.

"Isover Warm and Quiet Wall"

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

This version of "Isover" is used for internal and external wall insulation, as well as for frame buildings.

• "Isover Heat and Quiet Walls" has an increased vapor permeability parameter compared to other heaters, 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 straighten out 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 the expansion during self-expansion.

"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 a lower thermal conductivity and an increased sound insulation index.

"Isover Heat and Quiet Wall Plus" is designed to insulate walls from the inside of the building, as well as from the outside under the decorative layer of siding, slabs, lining or facing bricks. In addition, using additional protective materials, such as wind-waterproofing and vapor barrier membranes, these boards can also be used to insulate frame structures.

Recommendations for internal wall insulation from the manufacturer

Work on the installation of insulation mats or plates on the walls between wooden racks or metal profiles is quite simple, with the correct marking and installation of the elements of the crate.

• The first step is to fix the crate on the marked wall. Racks are installed at a distance from each other, depending on the width of the insulation material. So, if the width of the plate is 600 mm, then the racks must be fixed in increments of 590 mm.
• Further, insulation material is installed between the fixed racks. It can be mounted in one or two layers, depending on the required thickness.
• If a metal profile is used for the frame, it may be necessary to additionally fix the plates on the wall with dish-shaped dowels - “fungi”. When installing a crate from a bar, there is usually no need for additional fixation of the insulation, since it is securely held due to self-expansion.

• After all the insulation is installed in its place, it must be tightened from the side of the room 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 airspace 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.
• Further, drywall plates, one of the types of lining or decorative plates are fixed to the frame elements.

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

Isover materials for roof insulation

To insulate the roof, Isover 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 also highly specialized heaters "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 designed to insulate roof slopes of different configurations, but have different characteristics, in terms of release form, linear dimensions and material of manufacture. They are united by the fact that heaters for this area of ​​application undergo a special treatment using the AquaProtect technology, which provides 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 a polyethylene package, on which markings are applied for the convenience of cutting the material along its width.

• "Isover Pitched Roofs" - made from basalt fibers in the form of slabs, which are pressed and also packaged in polyethylene.

These materials are suitable for thermal insulation of the surfaces of pitched and mansard roofs, as well as, by the way, for wall surfaces from the inside and outside under cladding with decorative panels and facing bricks.

The procedure for installing insulation in the roof truss system is described in the "Isover Profi" section.

Floor insulation and soundproofing

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

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

Products not only insulate surfaces, but also significantly reduce the noise coming from the insulated room to the one below the floor and vice versa.

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

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

Products have high strength characteristics due to the technology of vertical arrangement of fibers.

Recommendations for installing an insulated floating floor

"Floating" refers to the design of the floor, which is not fixed to the base, for example, to the floor slab.

If it is supposed to make a “wet” cement-sand screed covering the insulation, then the plates laid on the base must be covered with a layer of waterproofing. This material is intended to protect the insulation from the penetration of moisture from the concrete solution. Waterproofing sheets are overlapped by 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, before installing the insulation, it is necessary to install a damper tape around the perimeter of the room or narrow strips cut from the 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 adjoin the walls and will not directly transmit noise vibrations. In addition, such a damper will keep the screed intact during linear expansions caused by temperature changes.

Isover materials for building soundproofing

To protect the house from external and internal noise, the company produces two types of specific material - Isover Quiet House and Isover Sound Protection. However, in addition to them, for this purpose, the above-mentioned universal heaters "Classic" and "Profi" can be used, which have characteristics that are quite suitable for this purpose.

• "Isover Quiethouse»

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

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

• "Isover SoundProtection"

"Isover ZvukoZaschita" are slabs molded from basalt fiber, which have a pronounced elasticity. Due to this quality, they are easy to mount in a frame crate, installed in the form of a partition or fixed to the wall.

Soundproof boards can be used in combination with other insulation 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 sound insulator layer will not only prevent extraneous sounds from entering the house, but also retain the accumulated heat, preventing it from escaping through the ceiling.

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

Manufacturer's recommendations for soundproofing installation

• The slabs should fit snugly against each other or against the elements of the crate, since even small gaps can significantly reduce the level of sound insulation.
• It is best to cover the insulated wall with plasterboard sheets - it also absorbs sound waves well, resonates much less compared to wood-based sheets - plywood, fiberboard, chipboard, OSB, etc.
• Before sheathing with drywall, mineral wool must be covered with a material that does not let dust into the living quarters along with microscopic fragments of fibers. At the same time, such a membrane should act as a vapor barrier.
• If metal profiles are used for the frame, it is recommended to stick a vibration-proof 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, therefore, during installation, care should be taken that they are not more than 2 ÷ 3 mm. If this was not achieved, it is best to use silicone and acrylic-based sealants to seal them, as they also have a soundproofing effect, do not crumble and adhere securely to the surface.

Materials for thermal insulation in the bath and sauna

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

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

The following points can be attributed to the features of this heat-insulating material:

• The mats consist of two layers: the main one, made of mineral wool based on glass fiber, and the outer one, made of foil. At the same time, mineral wool is characterized as a non-combustible material, and the foil coating belongs to the G1 combustibility class, as it withstands surface temperatures up to 100 degrees, mostly due to the adhesive layer that holds the foil. With higher heating, this layer loses its elasticity and, under direct exposure to a flame, can ignite, although being self-extinguishing. To prevent this from happening, as well as to give the walls a decorative effect, they are usually sheathed with wooden clapboard.
• "Isover Sauna" takes on two functions: it is a good heat insulator and at the same time - a vapor barrier that protects the mineral layer from abundant evaporation, which are an integral part of a bath or sauna.
• The foil layer has the ability to reflect 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 an approximate scheme for installing materials:

• The wall of a log house (there may well be any other wall of the bath).
• Timber framing. In this case, it is installed horizontally, but this is not important.
• Insulation "Isover Sauna".
• Spacer strips that create an air gap.
• The interior lining of the premises is made of natural lining.

Installation of "Isover Sauna" on the walls is not very different from the installation of conventional heaters, except for some nuances:

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

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

And what is the thickness of the material "Isover" is necessary for effective thermal insulation?

We hope that after getting acquainted with the range of Isover heaters, the purpose and characteristics of each type, the interested reader will be able to choose the best material for their needs. But here's another question - how thick should the insulation be in order for it to really fulfill its role, so that a comfortable microclimate is maintained in the premises?

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

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

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

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

R=h/λ

R is the required resistance to heat transfer;

h is the thickness of a particular layer;

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

• Thus, knowing, for example, the thickness of the wall requiring insulation, and the material of its manufacture, it is easy 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 a layer-by-layer calculation, the values ​​are summarized.
• Then the total value must be compared with the normalized value established for your region. You will get a difference (usually very impressive), which the insulation material should make up for.
• Well, knowing the thermal conductivity of the selected insulation, it is easy to determine the required thickness by the formula.

“In words”, perhaps, it will seem difficult to someone, but with our online calculator, which takes into account the necessary tabular values ​​​​and the necessary dependencies, the calculation will not be difficult.
