Isover insulation standard technical specifications. Izover insulation - technical characteristics

Glass fibers are the basis of ISOVER. The length of one of a thousand fibers reaches 150 microns with a thickness of 5 microns. These parameters make the material very elastic and durable.

ISOVER can be used at any stage of building construction. Manufacturers promise the highest level of thermal protection.

ISOVER technical characteristics are as follows:

• Low thermal conductivity coefficient. It provides a high degree of thermal protection
• Excellent sound reduction properties. Provides the ability to significantly reduce noise levels
• Highly environmentally friendly material. Can be used to insulate any room
• Durability. This material can last at least 5 decades
• Non-flammability. It really doesn’t burn, but at high temperatures it can melt
• Light weight. Thanks to this indicator, isover can even be used for insulation of stacked structures

The density of the airtight ISOVER is 13 kg/m3. During installation, it is possible (due to the softness of the material) to reduce the tightness of the seal to the wall.

When purchasing ISOVER, it is worth asking for quality certificates. If the material is produced under license, the seller must demonstrate documents confirming the standards EN 13162 and ISO 9001. They guarantee that ISOVER is made from safe materials, and therefore there is no prohibition for its use indoors.

Isover glass wool types and technical characteristics

Izover is produced in rolls, mats and slabs, which differ in their dimensions.

Glass wool is made from residues from the glass industry, or less commonly from the basic raw materials used to produce glass. There are some restrictions that narrow the scope of use glass wool insulation Izover. The technical characteristics of the material exclude operation in a damp environment without additional protection. This insulation absorbs moisture very strongly and dries poorly. Moreover, when the material gets wet, it ceases to perform the functions of thermal insulation. Therefore, you need to use special films that prevent moisture from penetrating into the Izover insulation. Reviews clearly confirm the failure of the material without steam and waterproofing.

Glass wool is available in:

• rolls;
• matah;
• slabs

What's the difference between them? Rolls are soft rectangular pieces of insulation, which differ from mats in their length (they are longer). Mats are also wrapped in rolls, but they are shorter and somewhat denser. Usually two mats are wound in one roll. The slabs are denser, they do not roll into rolls and are sold in rectangular packages. Various materials are used for interior and exterior work. Izover mineral wool insulation - characteristics common to all positions:

• thermal conductivity coefficient – ​​ranging from 0.037 to 0.044 W/m*C;
• flammability group - NG, that is, does not burn;
• moisture absorption is high.

Let's take a closer look at Isover insulation. The technical characteristics of each type differ quite a bit, mainly dimensions and density.

Before insulating a wall in a panel house from the inside, consider the option of external work; according to technology, this is more correct.

The technical characteristics of Asstratek liquid insulation are described here.

Rolls

Sauna – thickness 50 and 100 mm, laminated with foil. Used for wall insulation different types baths from the inside.

Mats

Pro - used indoors and outdoors, a universal material that is popular. Thickness 50, 100 and 150 mm. Classic – thickness 50 mm, 2 mats wound in a roll. It is used for insulation of floors, roofs along joists, and ceilings along lathing. M37 frame - thickness options 40, 50, 60, 100 and 150 mm. It is used to fill the space between walls when insulating frame houses. Frame M34 - thickness 50 mm, less dense than M37. Frame M40AL – foil insulation with a thickness of 50, 100 and 150 mm.

Plates

Isover mineral wool can be with foil, which protects it from moisture.

• Convenience when insulating large surface areas, ease of installation due to the fact that one roll can insulate a large area of ​​the house.
• When used, fewer joints appear, and therefore, air flow throughput decreases.
• Low material consumption.
• Suitable for non-standard rafter spacing, easy to cut to the required width.

Insulation in slabs

• Recommended for insulating small rooms.
• Suitable for one person use.
• They are fixed by surprise without the use of additional fasteners.

Application of Izover, its specifics and varieties

It is known that approximately forty percent of heat loss occurs through the wall partitions of the building, so insulation " weak points» quality material, subject to and following all installation rules, this is a guarantee of heat preservation in the house. As a result, spending on more expensive and reliable insulation will provide further savings on heating all rooms during the cold season.

The manufacturing company invites customers to choose the most suitable insulation among several types, which can be divided depending on the area of ​​application.

Areas of application of Izover thermal insulation:

• roofs and ceilings;
• external walls;
• internal, interior partitions.

Izover KL-34

This type of Izover product consists of slabs, the thickness of which can be 5 or 10 centimeters. It is suitable for insulating any planes - vertical, horizontal, inclined. Due to the tight fit on the frame, the use of additional fasteners is not required. KL-34 slabs are often used to insulate ventilated facades.

Izover KL-37

A soft fiberglass based insulation that is designed to work in buildings where the insulation is not heavily stressed. Interestingly, the packaged material is subjected to additional compression by 2 times - this helps reduce the overall volume, thereby slightly reducing delivery costs. Like previous view Izover insulation, KL-37 does not require additional fasteners. However, it should be remembered that during installation it is necessary to comply with the condition - to strive for the tightest possible fit of the slabs to the surface.

Izover KT-37

It is used for insulation of attics, roofs, as well as interfloor ceilings. The main difference from KL-37 is that it is a roll material. The remaining characteristics, recommendations for operation and installation are the same.

Izover KT-40

It is supplied in rolls and, unlike other Izover products, this type of material consists of two layers, each of which is 5 centimeters thick. KT-40 will be an ideal option if installation is carried out in a wooden or metal frame, where the distance between the posts is 60 centimeters.

Isover STYROFOAM 300A

Produced in the form of slabs with extruded polystyrene foam. This material requires the use of fasteners. Thanks to the special composition of STYROFOAM 300A boards, the heat and moisture protection indicators are higher than those of many similar products. This type of Izover insulation has found its application in the thermal insulation of walls, floors and flat roofs. It is allowed to apply a layer of plaster directly on top of the slabs.

Isover VENTITERM

Insulation based on mineral wool with basalt fibers. The versatility of this material is due to the fact that installation can be carried out both with and without fasteners. Professionals have long found use for this insulation in insulating water supply systems and ventilation pipes.

Izover Pitched roof

Izover Pitched Roofing has been specially developed to protect the roof. This type of insulation not only allows you to retain heat, but also, thanks to its ability to absorb sounds from the outside, creates an atmosphere of peace and quiet. Positive properties also include the non-flammability of the material and good vapor permeability. It must be remembered that the pitch of the rafter system must correspond to the dimensions of the insulation boards.

Izover Soundproofing

Izover Sound Protection mats and slabs are designed specifically to minimize the possibility of penetration of extraneous noise from the outside. Installation can be carried out in internal partitions or suspended ceilings.

Isover Sauna

Insulation Izover Sauna. In addition to the fact that this material has all the qualities of high-quality insulation, Izover Sauna also creates a barrier to steam, making it ideal for installation in baths, saunas and rooms with high humidity. The material is mats with a thickness of 5 or 10 centimeters and is supplied in rolls.

To make it easier to search and select the right product, the manufacturer of thermal insulation materials Izover has developed and presented a line of products indicating the purpose and area of ​​application right in the title:

• Izover Warm home.
• Izover Warm roof.
• Izover Warm walls.
• Izover Quiet House.

Basalt insulation

In addition to fiberglass slabs, basalt insulation based on stone fibers is produced under the Izover brand.

The main technical differences of basalt wool:

• higher price.
• basalt wool is more durable.
• stronger and denser than glass wool.
• less elastic, more brittle.
• higher moisture resistance and heat resistance.
• Available in slabs.
• lower compression ratio means transportation is more expensive and takes up more storage space.

Expert advice: basalt insulation is recommended for use in places with higher loads, because it has higher density.

In fact, the line of this mineral wool is not much different from fiberglass-based materials:

• Isover Optimal. Supplied in slabs of 50 and 100 mm thickness. Designed for insulation and sound protection of pitched roofs and ceilings.
• Light. Designed for frame structures, has increased elasticity. Mineral wool is supplied in slabs with thicknesses of 50 and 100 mm.
• Acoustic. Sound absorption class "A".
• Isover Ruf V, Ruf N. Designed for flat roofing.
• Isover Flor. Supplied in slabs with thicknesses of 30, 40 and 50 mm. Reduces impact noise by up to 35 dB.
• Isover Plaster. Used for plaster facades.
• Isover Facade-Master. Used for insulation of plaster facades. The thickness of the slabs is 30, 50, 100 and 150 mm.
• Venti. It is characterized by increased vapor permeability.
• Isover Standard. Used in multi-layer masonry.

It is impossible to say clearly which insulation is better, stone or glass wool. Both types have advantages and disadvantages - the choice depends on the conditions of use of the insulation and the requirements for it.

Today Izover is the most popular mineral wool on the domestic market building materials. Thanks to its diverse product line, high quality and affordable price, it receives best reviews from consumers. According to many builders, it has the best price-quality ratio among its competitors.

Watch the video explaining the features and advantages of Izover insulation:

Technical characteristics of Izovol insulation

The technical characteristics of insulation have not only positive qualities associated with thermal insulation. There are also secondary advantages, such as service life, environmental friendliness and the weight of the insulation, which plays a big role during installation.

1. Insulation service life- this is one of the most important factors. The insulation can last for 50 years without deteriorating the thermal insulation properties of the material. Surely no one will use a material that will last a year, because installing insulation is still not an easy job, and therefore, according to these criteria, it outperforms other models.
2. Many buildings require insulation, but you also have to monitor for environmental standards using one or another insulation. Many insulation materials are simply not suitable due to their low environmental aspects, and therefore most often when insulating residential buildings, kindergartens, hospitals and many others government agencies Isovol is used. The material has passed a lot of tests, including at the Cancer Institute, where it received a certificate of safety for use.
3. The weight of the material is quite small, so Izovol can be easily used on buildings that, to put it mildly, have already outlived their usefulness. The walls of many buildings may simply not withstand the load, but when using insulation, the walls will actually not feel any additional load.

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 international certification, 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.

Installation

Let's get acquainted with the features of installing building materials on various components of residential buildings.

Roof

Important! The insulator sheets must be laid across the roof slope, starting from the bottom, overlapping by 10 cm.

To install mineral wool on the roof, work must be performed in the following order:

1. Installation of vapor barrier from inside the roof.
2. Using roll insulation you need to cut off pieces equal to the roof slope and lay them between the rafters.
3. Mineral wool slabs are laid close to each other, since the quality of thermal insulation depends on this.
4. Laying a waterproofing membrane. It needs to be positioned with some hanging between the rafters.

Important! In order for Isover to be laid hermetically, the width of the slab must be 2-3 cm greater than the distance between the rafters.

Facade

To insulate the facade, mineral wool is used in slabs measuring 60*120 or 100*120 cm. You can use Isover standard. For temperate continental climate optimal thickness layer is about 10 cm. For areas with more severe winters, 15 cm slabs are used.

Installation work includes the following steps:

1. Installation of a profile at the bottom of the walls with a width equal to the thickness of the wool.
2. Installation of wool slabs close to each other using special glue applied at 6-9 points. You need to check the evenness of the walls using a level and a rule.
3. Each slab is fixed with “fungi” or “umbrellas”.
4. This is followed by work on installing corners, reinforcing and applying decorative plaster. Another option is cladding with siding or brick.

Characteristics of Izover

Minimal heat loss is ensured by the simple property of air placed in a closed space between the fibers of the material, which 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.

Areas of use

Izover mineral basalt wool is widely used in the field of thermal insulation. It is used for insulation of all civil and industrial facilities. There are practically no contraindications for its use. There are 4 installation methods for installing mineral wool:

• on a metal frame,
• on a wooden frame,
• on bracket fasteners
• on the base profile.

Choose the best way it is necessary according to the characteristics of the product, especially with regard to the correct choice of its size and standard modification. It is best to consult with the manufacturer. An incorrectly chosen method can lead to unforeseen circumstances such as rejection of multi-layer insulation or bulging of individual sections, as well as air gaps and cold bridges forming inside the sandwich.

Disadvantages of mineral wool

No matter how ideal the proven and technically tested material is, there are still negative aspects. As for Izover mineral wool, we can point out the only negative: the danger of stone dust. With direct contact it can cause bronchial asthma or allergic dermatitis, therefore it is recommended to work with cotton wool in overalls, gloves and a respirator.

Do-it-yourself installation of Izover mineral wool

For thermal insulation various designs The manufacturer has a wide range of products. Choose thermal insulation material should be based on its characteristics (mainly density) and the manufacturer’s recommendations. Mats with a low density are better suited for horizontal surfaces; for thermal insulation of walls it is better to buy slabs with a higher density.

Laying mineral thermal insulation in two layers will help eliminate the appearance of cold bridges and cracks in the structure.

Do not forget about high-quality vapor-waterproofing of the thermal insulation layer, since mineral wool can absorb moisture, thereby losing its thermal insulation characteristics. Before laying isover glass wool, waterproofing should be laid on the structure; you can use ordinary plastic film. The top of the mineral wool should be covered with a superdiffusion membrane.

How it is made

So, what is Isover insulation? Characteristics of any insulating material depend primarily on how accurately the required technologies are followed during its production. Isover insulation is manufactured as follows:

• Quartz sand, 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 With high altitude fed to 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.

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, interfloor ceilings 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(manufacturer declares 50 years warranty operation) can be an excellent insulation not only for a private house, but also for an apartment, as well as for non-residential buildings. Good luck with your choice and warm homes!

Specifications

Izover is a heat and sound insulating material, it is used for insulation of any structural elements inside and outside the building. It is necessary to level the surface under this insulation, since the main condition for using this insulation is a tight fit to the surface.

Main characteristics:

• low thermal conductivity;
• high level of sound insulation;
• resistance to infestation by fungi, small insects, and rodents due to special impregnations;
• ease of transportation and installation ensures the light weight of the material, its density is 13 kg/cub.m;
• elasticity of the material;
• resistance to chemicals;
• long service life.

Thermal conductivity

For thermal insulation materials, thermal conductivity is the main characteristic. For various types isover it ranges from 0.035 to 0.044 W/mK, which is much less compared to other analogues.

Provided the installation technology is followed, this characteristic will not change over time. This ensures the prevention of heat loss through the load-bearing and enclosing structures of the building.

Soundproofing

The structure of Isover insulation, consisting of thin glass fibers and an air layer, and low dynamic rigidity create effective noise insulation. It is used to provide sound insulation in structures where the soundproofing material does not bear the load.

Flammability

According to the current GOST 30244-94“Construction materials. Combustibility test methods", isover belongs to the class of non-combustible materials. Therefore, it is used for insulation and sound insulation indoors for various purposes and in low-rise construction.

Isover is also used as an effective insulation in log, frame or panel wooden residential and public buildings.

Vapor permeability

Vapor permeability of isover is 0.50 - 0.55 mg/mchPa and is one of the main disadvantages of this material. In the absence of a vapor barrier, the quality of the insulation will decrease as moisture accumulates.

When the humidity level increases by 1%, the level of thermal insulation decreases to 10%. But under the influence of temperature or sufficient ventilation, the material dries quickly.

To prevent moisture absorption, a vapor barrier is used, and a ventilation gap of 2 - 4 cm is left between the isover and the wall.

Life time

Heat and sound insulation the quality of the material does not deteriorate over time if the installation technology is followed. For 50 years, the thermal insulation parameters of isover in building structures have not deteriorated.

Environmentally friendly and harmless

Izover made from natural materials, it does not contain harmful substances such as artificial resins, formaldehyde. This is a hypoallergenic material that is safe for human life. Based on the research, it was revealed that there are no harmful emissions during operation.

Insulation weight

What is the weight of the insulation? Isover weight much less than similar insulation materials. The specific gravity of isover is 2.5. Therefore, it is used for insulating buildings made of wood, slag concrete, and thin-walled brick.

Release form

Izover Available in the form of slabs and rolls in packaging. The elasticity of the material allows it to be compressed in packaging, which is very convenient for storage and transportation. After opening the package, the isover quickly acquires its initial dimensions. Roll sizes are 7-14 meters long, 1.2 meters wide.

Other characteristics

Double layer rolls can be divided into layers before installation. Isover cannot be used at temperatures above 250 degrees Celsius

In a humid environment, isover:

• has water-repellent properties;
• slowly absorbs moisture and water.

These Isover insulation materials have a certificate of conformity and meet all safety standards listed in the requirements of the Customs Union.

Characteristics of Izover

Before you buy Izover, it would be a good idea to learn about all the features of this material, its technical characteristics, advantages and installation principles. There is a fairly wide variety of this material on the market, the parameters of which are given below:

• Thermal conductivity - 0.031-0.041 W/mK. Such a low indicator results in excellent insulation and heat saving performance with stable preservation over a long period.
• Density - 10-20 kg/m3.
• Flammability. Isover belongs to the NG class (completely non-combustible materials). Foil and semi-rigid insulation of this type belongs to the SG category (slightly flammable).
• Vapor permeability - 0.5-0.55 mg/mchPa. Fiberglass absorbs moisture, but releases it completely as it dries. Therefore, subject to the installation rules and the design of the ventilation gap between the layers, problems with reducing thermal insulation properties not visible.
• Air permeability - 120x10-6m3/m*s*Pa.

Sound insulation corresponds to high levels, due to the presence of an air gap between the fiberglass.

• Operating period. The warranty guarantees a service life of at least 50 years.
• Weight. Isover is lightweight and therefore suitable for installation on structures with low load-bearing loads.
• Release form. This insulation is supplied to the current market in several versions - rolls, mats, slabs.
• Thickness -5-10 cm with 1 or 2 layers.
• The width of the rolled web is 1.2 m with a length of 7-14 meters.
• The area of ​​the rolls is 16-20 meters, the slab material is produced in the size of 1 * 1 meter. Important! The price of Izover depends on the type of material, release form and supplier.

Installation of Izover

Izover is mounted exclusively in a dry way - mainly on a frame made of metal profiles or wood.

Important! One of the advantages of using this insulation is that careful preparation of the base is not required. You can even smooth out all the flaws while laying the canvas

And this entails not only savings on consumables, but also reduces the time spent on the entire process.

But what materials should be used to insulate walls, information will help you understand

Izofer is a well-known brand for the production of high-quality thermal insulation materials. He has a variety of products in his assortment, each of which has its own technical characteristics and scope of application. But they are all united by such qualities as durability and low thermal conductivity.

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

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

A few words about the insulation manufacturing company “Isover”

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

Vast, centuries-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 directions. These are high-tech materials, ordinary flat glass and created for special application, 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 in terms of its environmental friendliness with 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 as a result of processing quartz sand, broken glass or mineral rocks of the basalt group - their melting and subsequent stretching using TEL fiberization technology. The resulting thin, almost microscopic threads with a thickness of 4–5 microns and a length of 110–150 microns are connected to each other with special resins.

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

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

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

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

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

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

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

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

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 is achieved thanks to the structure of the material, since air gap between 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 it will not create favorable environment for the appearance of pathogenic microflora, 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 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 precisely these binders. There are certain exceptions, but they are still so expensive that not every homeowner can afford such thermal insulation.

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

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

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

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

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

Prices for “Isover” insulation

Isover insulation

Universal insulation materials "Isover"

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

Their technical and operational characteristics are given in the table:

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

	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 outside the insulation is covered 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 secured to the frame posts using staples and a stapler. The top sheet must be overlapped with the bottom sheet by 120÷150 mm; the joints of the membranes must be sealed by gluing moisture-resistant adhesive tape on them.
• After this, a counter-lattice is attached to the frame, on top of the film, onto which the facing material will be fixed. Thanks to this approach between insulation and decorative finishing a ventilation gap is created, facilitating the spontaneous removal of water vapor and evaporation of condensate.
• The final stage is to attach it to the frame structure, first from the street side, then from the inside of the house.

"Isover Pro"

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

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

• “Isover Pro” has one of the lowest thermal conductivity values ​​of all materials from this manufacturer.
• Due to the fact that special markings are applied to the mat, it is convenient to cut. At the same time, even if a non-standard structure is insulated, a minimum of waste remains from the material.
• The insulation is produced 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 heat-saving insulation materials presented by Isover - its use reduces heat loss to a minimum.

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

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

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

Basic parameters of insulation	"Isover Warm Home"	"Isover Warm Home Stove"
Thermal conductivity coefficient, at 10˚С, W/m×˚С	0,040	0,040
Airborne noise insulation index Rw (dB)	45	45
Moisture absorption during partial immersion in 24 hours, kg/m², no more	1,0	1,0
Vapor permeability mg/m×h×Pa	0,55	0,55
Insulation density, kg/m³	11,0	11,0
Flammability group	NG	NG
Thickness, mm	50	50 and 100
Width, mm	1220	610
Length, mm	5490 and 7000	1170
Volume of insulation in packaging, m³	0.67 and 0.85	0.5 and 0.5
Insulation area in packaging depending on thickness, m²	13.4 and 17.1	10 and 5
Number of mats per package, depending on thickness, pcs.	2 and 2	14 and 7

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

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

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

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

Isover mineral wool for specific applications

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

Insulation of the facade for further plastering

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

Basic parameters of insulation	"Isover Facade-Master" (slab)	"Isover Plaster Facade" (slab)	"Isover Facade" (slab)	“Isover Facade-Light” (slab)
Thermal conductivity coefficient, at 10˚С, W/m×˚С	0.036÷0.040	0.038÷0.040	0.037÷0.042	0,034
Airborne noise insulation index Rw (dB)	45	45	45	55
Moisture absorption during partial immersion in 24 hours, kg/m², no more	1,0	1,0	1,0	1,0
Vapor permeability mg/m×h×Pa	0,3	0,4	0,55	0,4
Insulation density, kg/m³	125,0	80,0	125÷155	50,0
Flammability group	NG	NG	NG	NG
Thickness, mm	50, 100, 150,200	50, 100, 150	50, 100,150	50, 100,150
Width, mm	600	600	600	600
Length, mm	1200	1200	1200	1200
Volume of insulation in packaging, m³	0,288	0,288; 0,288; 0,216	0,144; 144; 0,216	0,288; 0,216; 0,216
Insulation area in packaging depending on thickness, m²	1,44; 1,44; 2,16; 1,44	5,76; 2,88; 1,44	2,88; 1,44; 1,44	5,76; 2,88; 1,44
Number of mats per package, depending on thickness, pcs.	4,0; 2,0; 2,0; 1,0	8,0; 4,0; 2,0	4,0; 2,0; 2,0	8,0; 3,0; 2,0

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

Prices for “Facade-master” plaster

Facade master

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

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

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

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

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

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

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

• After this, without a pause, a reinforcing 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 the “wet facade”, or again the same 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)

Number of mats per package, depending on thickness, pcs.	14,0; 7,0	1,0	8,0; 4,0	10,0	8,0; 4,0

"Isover Standard"

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

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

"Isover Warm Walls"

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

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

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

"Isover Warm and Quiet Wall"

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

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

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

"Isover Warm and Quiet Wall Plus"

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

“Isover Warm and Quiet Wall Plus” is designed for insulating walls from the inside of the building, as well as from the outside under decorative layer 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 insulation walls from the manufacturer

The work of installing insulating mats or slabs on walls between wooden studs or metal profiles is quite simple, provided that the sheathing elements are correctly marked and installed.

• The first step is to attach the sheathing to the marked wall. The racks are installed at a distance from each other depending on the width of the insulation material. So, if the width of the slab is 600 mm, then the racks need to be fixed in increments of 590 mm.
• Next, insulating material is installed between the fixed posts. It can be installed in one or two layers, depending on the required thickness.
• If a metal profile is used for the frame, you may have to additionally fix the slabs on the wall with disc-shaped dowels - “fungi”. When installing timber sheathing, there is usually no need for additional fixation of the insulation, since it is securely held due to its self-expansion.

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

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

“Isover” materials for roof insulation

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

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

"Isover Warm Roof" And "Isover Pitched Roofs"

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

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

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

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

The procedure for installing insulation into the roof truss system is described in the “Isover Pros” section

Insulation and soundproofing of the floor

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

Basic parameters of insulation	"Isover Floor" (slabs)	"Isover Floating Floor" (slabs)
Thermal conductivity coefficient, at 10˚С, W/m×˚С	0,036	0,033

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

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

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

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

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

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

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

In addition, when arranging any 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 above mentioned ones can also be used for this purpose. universal insulation“Classic” and “Pro”, which have characteristics quite suitable for this purpose.

• "Isover Quiethouse»

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

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

• "Isover Sound Protection"

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

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

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

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

• The slabs must fit tightly to each other or to the sheathing elements, since even small gaps can significantly reduce the level of sound insulation.
• It is best to cover an insulated wall 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 used for the frame metal profiles, it is recommended to stick vibration-proofing tape on their outer surface before fixing the drywall, which will also help reduce the noise level.
• The gaps allowed between the plasterboard sheets will reduce the soundproofing effect, so during installation you should try to ensure that they are not more than 2÷3 mm. If this cannot be achieved, it is best to use silicone and silicone sealants to seal them. acrylic base, since they also have a soundproofing effect, do not crumble and adhere securely to the surface.

Materials for thermal insulation in baths and saunas

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

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

Basic parameters of insulation	"Isover Sauna", mats in rolls
Thermal conductivity coefficient, at 10˚С, W/m×˚С	0,041
Airborne noise insulation index Rw (dB)	54
Moisture absorption during partial immersion in 24 hours, kg/m², no more	1
Vapor permeability mg/m×h×Pa	vapor-tight
Insulation density, kg/m³	30
Flammability group	G1 based on NG

Volume of insulation in packaging, m³	0,75
Insulation area in packaging depending on thickness, m²	15,0; 7,5
Number of mats per package, depending on thickness, pcs.	1,0

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

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

To understand the installation process, you can consider an approximate diagram of the installation of 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 make some thermal calculations. Usually they are carried out by socialists, but for a private developer a somewhat simplified algorithm for determining the thickness of thermal insulation is sufficient. Let's try and you will see that everything is not so complicated.

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

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

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

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

R=h/λ

R– required heat transfer resistance;

h– thickness of a specific layer;

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

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

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

The ISOVER company (Izover) occupies a leading position in the world market in the production of insulation materials for any type of structure.

Izover slabs are considered the most the best insulation materials in the construction market. Most of the production volume of ISOVER insulation occurs abroad, but in Russia, insulation is also produced in the Moscow region, in the city of Yegoryevsk. A large plant producing heat and sound insulation, in addition, the plant is the only one that produces mineral wool based on quartz and basalt.

What you need to know when choosing insulation

Thermal conductivity coefficient (λ)

When choosing thermal insulation products, firstly, you need to pay special attention to such an indicator as the thermal conductivity coefficient - λ (lambda). How less value lambda, the better the house can be insulated, due to the fact that the thermal conductivity value reflects how much heat passes through the insulation per unit of time.

Thermal conductivity coefficient is measured as W/(m*K). (watt per meter per kelvin)

Types of thermal conductivity coefficient (λ)

Dry lambdas (installed by the manufacturer at the factory):
λ10 - thermal conductivity coefficient recorded at 10°C. An indicator declared by the manufacturer.

Wet lambdas (set by the manufacturer at different degrees of humidity):
λA and λB - thermal conductivity coefficients for different operating conditions (according to SP 50.13330.2012). Measurements are carried out by licensed laboratories at material humidity of 2% and 5%. The coefficient is used when thermal calculations in construction.

Choose insulation based on its thermal conductivity value, because the lower the coefficient, the more effectively the house will be insulated. For example, if the thermal conductivity value is 0.036, this will be enough for 50 mm of thermal protection to replace 95 cm of brick

Which insulation to choose: in slabs or rolls?

All ISOVER products have high elasticity, which means that the material holds tightly and stably without the use of additional fasteners. Both rolls and slabs are used in different designs. The shape is determined depending on the room.

• Convenience when insulating large surface areas, ease of installation due to the fact that one roll can insulate a large area of ​​the house.
• When used, fewer joints appear, and therefore, air flow throughput decreases.
• Low material consumption.
• Suitable for non-standard rafter spacing, easy to cut to the required width.

• Recommended for insulating small rooms.
• Suitable for one person use.
• They are fixed by surprise without the use of additional fasteners.

Do-it-yourself installation of Izover mineral wool

The manufacturer has a wide range of products for thermal insulation of various structures. Thermal insulation material should be selected based on its characteristics (mainly density) and the manufacturer’s recommendations. Mats with a low density are better suited for horizontal surfaces; for thermal insulation of walls it is better to buy slabs with a higher density.

Isover for roof insulation

The number of materials for thermal insulation is constantly growing. More and more consumers are realizing the need to insulate walls, roofs and foundations of private houses and other buildings. The technical characteristics and advantages of Izover insulation encourage some to use this particular material. What he really is? What are its advantages and properties?

What is Izover insulation?

This insulation is represented by mineral wool - a fibrous material that is manufactured in the form of slabs, rolls and mats. The thickness of the glass fibers is 4-5 microns, and the length is 100-150 microns. Only used for production natural ingredients, so there is no need to worry about the environmental friendliness of the material.

Plates can be rigid or semi-rigid. The insulation is installed both horizontally and vertically, both during interior work and when arranging facades.

Izover

It is made from sand (quartz) and broken glass. To improve certain properties, soda, borax, limestone and other components can be added to the material. The entire mass is poured into a special bunker. There the process of melting the ingredients takes place. When the molten glass leaves the centrifuge, it forms filaments due to the steam blowing. When they hit the rollers, the aerosol-impregnated threads are leveled and form a carpet. Then at +250°C the polymerization process occurs. When the material cools, it is cut into rolls, mats and slabs.

Technical characteristics, advantages and disadvantages

Since insulation is the main role of Izover, it is worth paying attention to its thermal conductivity. The thermal conductivity coefficient is within 0.038 W/(m*K). Other advantages include the following factors:

• Good sound insulation. Using mineral wool in interior partitions you can achieve a good effect.
• It is not eaten by rodents and insects. Therefore, using such material for the facade, you don’t have to be afraid that holes from rodents will appear in it later.
• Easy to install. This material is published in various forms, so you can choose exactly the one that will be optimal for the job at hand.
• Long service life - 50 years.
• The material does not deform under compression and has tensile strength. Thanks to its good compressibility, it is convenient to transport.
• Resistance to extreme temperatures.
• The insulation is not flammable, therefore it corresponds high requirements fire safety.

Ceiling insulation

Disadvantages of the material:

• The need to use protective equipment during installation work. Although over time there will be no harm from mineral wool, when installing thermal insulation it is necessary to protect the respiratory system.
• High moisture permeability. If it gets wet during operation or during installation, the heat-shielding properties will be lost. Therefore, while studying facade works, mineral wool must either be covered or covered with a layer of plaster as soon as possible after installation. This will prevent the harmful effects of precipitation.

Safety precautions when working with mineral wool

Types of Izover

Due to the wide variety of forms, Izover mineral wool is used in a variety of fields. When building a house, it can be used to insulate ventilated facades, attics, floors, ceilings and internal partitions. Each model has its own purpose and is used in a specific area, so give general characteristics the material is difficult. However, each type can be considered separately.

Isover Optimal

Its density is 28-37 kg/m3. It is available in the form of slabs. It is used for a frame house. They can insulate roofs, floors, and walls. It is used as sound insulation for interior partitions and ceilings between floors. Slab dimensions - 60*100 cm, thickness - 5 cm or 10 cm. One package contains 4 slabs (10 cm) or 8 slabs (5 cm).

Izover Roof V Optimal is available in a smaller thickness - 3 or 5 cm. In most cases, it is used for flat roofs. Despite the small thickness of the material, its structure is homogeneous. It can withstand a load of 7 tons per 1 m2.

Isover Standard

This model is used for thermal insulation of facade walls before covering with siding or facing bricks. They also sheathe frame structures. They are produced in the same sizes as the Optimal series mineral wool. Among its characteristics, it should be noted low compressibility under a specific load of 2 kPa - 10%. The density of Izover Standard slabs is 50 kg/m3.

Isover Venti

This product is intended for insulation of ventilated facades, and there is no restriction on the height of the building. This is achieved by the fact that this material has high mechanical strength. It is also produced in slabs measuring 60-100 cm with a thickness of 5 or 10 cm. The density of the material is 85 kg/m3. Thanks to high vapor permeability Moisture is effectively removed from the structure. Like other mineral wool materials, Izover Venti does not burn.

Izover for ventilated facades

The Isover Venti Optimal model range has slabs with thicknesses from 3 to 20 cm. This allows you to choose the most suitable solution for each insulated facade.

Izover Facade

This the lineup used for insulation of plaster facades. If pebble plaster is chosen as the finishing material and the insulation will need to be covered with a thin layer of plaster, then this option must be chosen. The thickness of the produced slabs varies from 5 to 20 cm, width - 60 cm, length - 100 cm.

Density characteristics of Izover Plaster Facade - 145 kg/m 3 . For simplified and accelerated installation of such slabs on the wall surface, this material is available in other geometric dimensions - 60*120 cm.

Isover Classic

It is used for thermal insulation of floors and ceilings and is laid between joists. Izover Classic is produced in rolls, and during transportation, mineral wool is compressed 6 times. Density - 11 kg/m3. The width of the roll is 122 cm, the material in it is folded into two layers of 5 cm thick, so during installation it is easy to select the desired thickness of insulation. Since the width between the joists can be 60 cm, the mats are cut lengthwise into two parts 61 cm wide and laid tightly between the boards.

Thermal insulation of floors

Isover Sauna

This model also has a vapor barrier. The presence of a foil layer makes it possible to preserve the high temperature of the sauna for a long time. This will also save time on installation work, since two stages are performed at once and there is no need to install additional films or membranes. The thickness of Izover Sauna is 50 or 100 mm. It is used to insulate not only walls, but also ceilings in bathhouses.

Izover Master of Acoustics

It is used where it is necessary to create acoustic insulation. It is produced in the form of mineral wool slabs based on stone fiber. It is used for external walls, interior partitions, floors and ceilings, that is, wherever high-quality sound insulation by Izover Master may be needed.

Isover Flor

This type of insulation is used to protect against impact noise. It reduces noise levels by 35 dB. Isover Floor is produced by the manufacturer in the form of rigid slabs measuring 60*120 cm and 3-5 cm thick.

Izover Profi

This is the most warm material among analogues. It is produced in rolls and is used in many inclined structures, for example, for roof insulation, plasterboard partitions on metal frame. Izover Profi is also used before finishing the facade with siding or facing bricks. The thickness of the rolls is 5, 10 or 15 cm. The length of the roll is 4-5 meters.

There are other varieties of this insulation. Thanks to this variety, you can choose the most suitable material for high-quality execution thermal insulation works. You can also choose the thickness and dimensions of the insulation. By carrying out all the work correctly, you can significantly save heating costs and ensure comfortable indoor conditions.
