Izovol insulation technical characteristics, pros and cons, types

The building materials market is expanding and filling with new products. Now you can buy insulation from a foreign company at a normal price - after all, well-known companies are setting up production of their products directly in Russia.

However, our factories are not idle either and are already producing thermal insulation of quite decent quality. A good example is the new Izovol basalt wool. Moreover, it was manufactured not by franchise, but by original patented technology. So we will dedicate our review today to her.

An example of using Isobel slabs

Instructions for using this material for thermal insulation of pitched roofs are presented in the table:

This is what the roof slopes look like after installing a vapor barrier immediately before the sheathing

When thermally insulating partitions and horizontal surfaces, the material is installed according to a similar scheme. The main thing is to ensure protection from moisture and compaction!

Features of insulation

The area of ​​use of isobel is reducing the thermal conductivity of buildings for various purposes. In the production of insulation, EcoSafe technology is used, which reduces the amount of moisture absorbed by the material. Izobel slabs are a type of basalt wool (material with the lowest thermal conductivity coefficient) and are manufactured without the use of blast furnace slag. Usually the insulation has a standard size (1000×600 mm, 1000×1000 mm, etc.).

The resulting slabs weigh less and do not hold heat as well, but their density is higher, which affects durability. Similar izobel is used for cladding areas of the house where thermal insulation does not play a special role, but fire resistance and noise absorption are much more important (non-residential attics, ceilings, pitched roofs).

Advantages of insulation

Mineral wool would not have become so popular among consumers if it did not have a number of advantages. In relation to Izobel brand insulation, the qualities listed below are considered as such.

1. Excellent thermal conductivity - coefficient from 0.03 to 0.04 - one of the smallest among insulation materials. If we add to this the thinness and elasticity of basalt fibers, we get an almost ideal material that allows us to significantly save on heating the room.
2. Fire resistance - isobel belongs to group IV of fire safety materials. If there is a fire source nearby, its physical and chemical properties will remain unchanged; the slabs will also become a barrier to the spreading fire.
3. Long service life - insulation made from basalt stone lasts at least 50 years if storage conditions are met. Excess liquid will not affect the material in any way - the fibrous structure will easily allow steam to pass through and condensate to evaporate.
4. Weak water absorption - basalt is non-hygroscopic; only 1.5% of its volume can be filled with moisture. If water-repellent additives are used in production, the value is reduced to 1%.
5. Good vapor permeability - achieved by the fibrous structure of the material and promotes the use of isobel in baths, saunas or industrial premises.
6. Sound insulation - depending on the thickness of the slab, they completely or partially neutralize extraneous noise.
7. Resistant to corrosion, fungi, rodents, unattractive to birds.
8. Affordable price - isobel costs on average 15% cheaper than mineral wool analogues; for a slab of 1 sq. m and a thickness of 50 mm, the consumer will pay from 100 to 300 rubles.
9. Environmental safety - achieved by a minimum amount of chemical components used to increase water repellency, and this is not always the case.

The above is only part of the positive aspects of izobel insulation. Other benefits are easier to feel during operation rather than described.

Parameters of products of the IZOVOL trademark

Izovol thermal insulation products are made from high-quality gabbro-basalt rocks. To improve the quality of mineral wool, the company uses the technology of melting stone with gas. Slabs are formed from basalt thread, which can be used as insulation and fire insulation. The use of ECOSEF technology in production allows us to create mineral wool with a stable acidity level. The material becomes environmentally friendly, does not change geometric dimensions, and is durable.

Thermal insulation properties are the main criterion when choosing insulation. The fibrous material Isovol effectively resists the penetration of cold and heat. Under the same conditions, a 50 mm basalt slab is comparable to 2000 mm of concrete, 550 mm of brick and 165 mm of wood. The use of mineral wool will significantly reduce the cost of heating buildings; its thermal conductivity is 0.034-0.038/

The fireproof properties of the material make it possible to protect wooden structures from fire. Thermal insulation can withstand temperatures up to 1100 degrees and the direct action of fire, while it does not melt or change its characteristics.

Thanks to the chaotic arrangement of stone fibers, Izovol insulation dampens the propagation of sound waves and is used as a sound insulator.

The structure of basalt slabs gives them tensile strength and delamination, and at the same time makes them elastic. Insulation blocks are easily mounted on a curved structure.

The peculiarity of the production of mineral wool stone fibers ensures stable dimensions and high strength of the insulation; its service life has been increased to 50 years. The durability of the slabs is facilitated by their biological neutrality; mold and mildew do not grow on the material, and rodents do not live. Aggressive environments, acids and alkalis, also do not affect the strength of thermal insulation.

To ensure that the insulating material used for enclosing structures, roofing and flooring is not damaged by moisture, basalt products are produced with water-repellent properties. The addition of special preparations during production helps increase the hydrophobicity of the slabs. Water absorption of the material is only 1% of the volume.

The strength of mineral wool stone fibers ensures stable dimensions and high strength of the insulation; its service life has been increased to 50 years. The durability of the slabs is facilitated by their biological neutrality; mold and mildew do not grow on the material, and rodents do not live. Aggressive environments, acids and alkalis, also do not affect the strength of thermal insulation.

The environmental safety of Izovol insulation makes it possible to place them inside houses and apartments without threatening human health. The high vapor permeability of the products creates an optimal level of moisture and promotes effective steam circulation.

Group No. 1. General building thermal insulation

It includes many types of insulation; for the convenience of users, all technical characteristics are presented in table form.

Note! The above-mentioned “Noise Protection” is an insulation that also has excellent noise insulation characteristics. Izovol insulation comes in other types, let’s take a look at them

Features of isobel installation

Due to its ease of use, insulation is used almost everywhere. Thermal insulation with its help will be justified in the following places:

• partitions between floors;
• floor;
• roofs with a slope;
• attics;
• walls.

Like any other mineral wool, insulation requires two additional layers - hydro- and vapor barrier. The first protects the slabs from getting wet from the outside, the second - from the inside. When installing isobel on a sloping roof, it is recommended to create an air gap, the purpose of which is to remove accumulated condensate.

The key difference between isobel as mineral wool and polystyrene foam is that it is not mounted directly to the wall with glue, but is placed inside cells formed by a wooden sheathing. The advantage of this need is additional strengthening of the building frame, the disadvantage is financial investment.

Areas of use of Izovol heat insulator

The described type of insulation is widely used not only in private, but also in industrial construction. And it’s not surprising, because basalt wool is the best option for the following structures.

1. Facades of buildings with one or several floors (including under “wet” plaster).
2. Pipelines, ventilation channels.
3. Joists in the floor and, if the mineral wool used is characterized by increased density, under a concrete screed.
4. Industrial equipment, various types of production lines.
5. Pediments and attics (in this case, insulation can be done both from the inside and outside).
6. Garages, verandas, agricultural facilities.
7. Roofs (pitched and straight).
8. Ceilings and walls (material is laid from the inside).

Features of mineral wool Izovol

The body-insulating material Izovol has a number of advantages and disadvantages that are taken into account during the design of buildings and industrial complexes. Having familiarized yourself with the features of the insulation, you can compare all the “yes” and “no” in comparison with other brands of mineral wool and make a decision in the direction of Izovol.

List of advantages of Izovol mineral wool:

• It is made from environmentally friendly natural raw materials, therefore all type modifications are environmentally friendly materials. ECO-cotton wool Izovol is a serious competitor to well-known world brands.
• The product is approved by the Ministry of Health and Pediatrics of the Russian Federation.
• Durability: mineral wool is a resistant fire barrier (fire safety class NG), wool does not burn, it melts at a temperature of 1200ºC.
• Isovol is an excellent material for eliminating background noise.
• Hygroscopicity – zero.

Resistance to aggressive substances: absolute resistance to fuels and lubricants, acidic and alkaline agents, alcohol solutions and essential oils.

Does not collapse: rodents, insects and mold do not expose mineral wool to destruction and rotting. Endurance to temporary and permanent loads of a vertical and lateral nature. Durability – the life cycle of mineral wool is more than 80 years. Reasonable price. Zero thermal conductivity and high density. Wide range of products (casings, mats, rolls and plates).

Attention! The super quality of Izovol has been proven by multiple laboratory and technical tests. And the end result proved that a mineral wool slab with a thickness of 10 cm (slab density 100 kg/m3) is equal to masonry made of rounded timber 25 cm, building brick 160 cm, concrete 50-75 cm and sand-lime brick 200 cm thick

People's opinions

“I always thought Parok was the ideal insulation material until I talked to my neighbor in the country. It turns out that three years ago he mortgaged the entire house with Isobel and was pleased with the result. The temperature in the house in winter became much higher, and during this time the insulation itself did not lose any of its volume (at least where we were able to look under the cladding). I decided to buy one for myself – the material is really excellent.”

Maxim Medvedev, Moscow.

“To be honest, at first we were afraid to take Isobel - the brand is not particularly well-known, and there were no reviews about it. But the price turned out to be too attractive, so we took mineral wool for trial to insulate the outbuilding. With the onset of cold weather, the basalt thermal insulation showed itself to be excellent, the characteristics corresponded to the declared ones, and removal of the cladding after a year did not reveal any unpleasant surprises. Now we will only use Isobel.”

Andrey, Voronezh.

“I liked the new insulation in my work: it holds volume well, is easy to install, and the price, frankly speaking, is attractive. Of the minuses, I would mention the poor packaging - bulky and not very durable. It also turned out to be difficult to unravel the sheets lengthwise: even a sharp knife does not cut, but crushes the fibers. But across the blade, it cuts through basalt Isobel just perfectly.”

Grigory Miroshkin, St. Petersburg.

“I read good reviews about Isobel slabs, which supposedly do not produce allergenic dust, and bought them to insulate the ceiling. It turned out that they generated dust no worse than glass wool - although I worked in overalls, gloves and goggles, and then itched and coughed for a couple of days. Now I’ll think about how to close it from below more securely so that all this trash doesn’t fly into the rooms.”

Yuri, Belgorod.

Installation

The slabs can be installed independently. As an example, consider the protection of the pitched roof of a private house. The day before you should prepare all the necessary equipment and the plates themselves. When working we will need a tape measure, a knife, a stapler, bars and plastic film

It is also important to prepare the surface itself. The roof is checked for leaks, rot and other defects

They must be eliminated before insulation work begins, otherwise the thermal insulation may be seriously damaged.

After the necessary work is completed, a lathing made of wooden blocks is nailed to the roof rafters. The recommended cross-section of the components is 4*4 cm. The lathing creates a gap between the roof surface and the heat insulator, preventing condensation from penetrating into the room.

Installation of slabs

At the next stage, the installation of insulation boards is carried out. They are placed on bars between the rafters. They are fastened together with a construction stapler. To hide the seams, cover them with double-sided tape. All that remains is to lay a layer of vapor barrier. Polyethylene or other similar material may be useful.

The process ends with finishing. The insulation is covered with the selected finishing material, for example, plasterboard.

Characteristics and parameters

Currently, manufacturers offer isovol in mats and rolls. As mentioned above, this is basalt wool, which is made by melting and drawing threads from the molten stone mass. It is the fibrous structure that creates the possibility of the formation of air capsules between the threads, and this, in turn, is the most powerful thermal insulation.

The production of isovol is modern; high-tech equipment and high-quality raw materials are used here, so the technical characteristics of the material can be classified as “high”. Let us add that this technology is patented and has an international quality certificate ISO9001:2000 No. 41060. Domestic can be considered a leader in this area.

Heat map of Izovol insulation use

Advantages of insulation

• Isovol TechnoNIKOL mineral wool insulation made from natural materials is environmentally friendly. It is harmless to human health and life. It is distinguished by:
• High fire-fighting properties. The insulation begins to melt at a temperature of +1110C. These are irreplaceable qualities for modern construction.
• Basalt fibers inside the material are arranged randomly, which is why isovol has high sound-absorbing properties. This is another huge plus.
• High coefficient of vapor permeability. If we compare this indicator with other heat insulators, then isovol can give many a head start.
• This insulation is not spoiled by rodents, bugs and other small insects do not grow here, mold and fungi do not multiply in it. TechnoNIKOL insulation laid on a metal surface protects it from the negative effects of moisture, which means that there is no corrosion of metals under the insulation.
• During operation, mineral wool heat insulator does not lose its shape, size and quality.
• Long service life, which depends on the degree of water absorption. It makes up only 1% of the total.
• Quite high thermal performance indicators, which we will discuss below.

The material is environmentally friendly Has fire-fighting properties Durability meets standards

A table with technical characteristics will definitely be presented, but I would like to make a comparison with other building materials.

TechnoNIKOL isovol with a thickness of 100 mm and a density of 100 kg/m³ can replace:

• wood 225 mm thick;
• ordinary brickwork – 1600 mm;
• silicate brick masonry – 2000 mm.

Flaws

This thermal insulation material has one drawback - its high price. But it is compensated by a huge number of advantages. So it makes sense to take a closer look at it.

Basic properties and characteristics of the material

Izovol insulation characteristics

has only positives and all thanks to the fact that only high-quality materials are used in production and production technology is strictly followed. Let's take a closer look at the benefits of insulation.

Low thermal conductivity

. The use of modern equipment has made it possible to produce insulation that combines:

- efficiency;

— reliability;

- safety;

- durability.

The low degree of thermal conductivity of insulation is one of its most important advantages. Izovol insulation is resistant to any type of load and has low thermal conductivity, which allows it to be used for insulating surfaces regardless of their operational loads. Using this type of insulation allows you to minimize the transfer of heat from a warm surface to a cold one, thereby increasing heating efficiency and at the same time reducing heating costs. insulation for walls

It has high technical characteristics, which is why the material has gained such enormous popularity among consumers.

The low thermal conductivity of the building material in question is explained by its fibrous structure, which contains many micropores that prevent thermal radiation and air convection.

High degree of fire resistance

. In the production of Izovol insulation, special stones, which are classified as non-hot substances, are used as the main material. When in contact with a flame, the material is able to maintain its high physical and mechanical characteristics for a long time and, in addition, prevent the rapid spread of fire.

Izovol insulation has a high temperature limit in comparison with many other known insulation materials (slag wool, glass wool). Thus, the type of insulation in question is capable of withstanding temperatures exceeding 1000°C for a long time.

Thus, Izovol insulation characteristics

whose fire resistance is quite high, it is successfully used when insulating building structures, regardless of their main purpose. It is important to know that Izovol insulation belongs to the first group (highest) fire-retardant efficiency.

Hydrophobicity.

Moisture that penetrates into the structure of the insulation contributes to the destruction of its structure and the formation of mold and the development of fungus on the surface of the wall. However, if Izovol slab is used as insulation, then these and many other problems can be easily dealt with. During the production of the material, special moisture-repellent elements are added to the composition, which significantly increases the moisture resistance of the insulation.

IZOVOL thermal insulation is used to insulate building structures, regardless of its main purpose. The durability and reliability of the material is explained by the level of water absorption, which for this material is no more than 1% of the total volume of the material. No other insulating material has an equal or lower water absorption rate.

High sound insulation

. The material is able to effectively retain sound waves, regardless of the source of their occurrence, thereby increasing the level of comfort in the room.

Izovol products have excellent sound insulation characteristics that meet the requirements specified in regulatory documents. Due to its ability to prevent noise from penetrating into rooms, this type of insulation is especially advantageous to use if the walls of the room overlook the roadway or other places that are a source of noise.

High degree of vapor permeability

. This characteristic is one of the most important advantages of the material. Moisture from the room passes freely through the structure of the insulation, after which it is removed from the material as a result of evaporation. This has a positive effect on the operation of the structure, since excess moisture is promptly removed, so that mold and mildew do not form on the wall surface.

Environmental Safety

. The insulation contains no harmful components that can cause harm to human health, so the material can safely be used for insulating residential premises. The use of Izovol insulation allows you to provide a normal microclimate in the room and increase the degree of hygiene of the room.

Chemical resistance

. Izovol insulation is not aggressive. The advantage of the material is its resistance to organic substances such as acids, solvents, alkalis. In addition, the material is able to provide structures with protection from corrosion, which guarantees increased operational and other characteristics of the room as a whole. The insulation meets the requirements of sanitary and hygienic standards, and is also characterized by stability of shape and size, resistance to mold, fungi and microorganisms.

Izovol insulation materials, regardless of operating conditions, are not subject to shrinkage. It is important to know that the coefficient of linear expansion in this material is “zero”. The material is simple and easy to work with; cutting it does not require a special tool; all you need is a sharp knife.

Durability.

The choice of material should be made based on many parameters and selection criteria, but when choosing, one should not forget about the durability of the material, that is, for how long it can serve efficiently. During testing, Izovol insulation materials showed amazing durability results (more than 2300 cycles). Due to the fact that the highest quality materials were used in its production, the insulation can last more than 50 years, regardless of operating conditions.

Izovol insulation materials, which were produced on the basis of natural basalt stone, have the longest service life. During the production of insulation, Izovol specialists managed to develop a unique composition of fibers at the molecular level, resulting in optimal acidity stability. Ultimately, it was possible to significantly improve the performance characteristics of Izovol insulation.

And finally, we note that Izovol insulation is the most stable and stable thermal insulation material, capable of maintaining its technical and operational characteristics for many years.

The plant's products include the following slabs:

IZOVOL “Noise Protection” - designed for sound insulation of rooms and buildings, the slabs have a size of 1000x600 mm, thickness from 40 to 250 mm, in increments of 10 mm. Has a flammability group - NG

IZOBEL (ISOBEL) - the lightest slabs, with a density of 25 kg/m3, used for thermal insulation of non-loaded structures (partitions, floors with joists, interfloor ceilings)

IZOVOL slabs, general building thermal insulation of higher densities, the names are quite short, but it’s not difficult to understand by the name where the slab is used

Izovol L-35 - light, non-loadable structures

Insulation of external walls under ventilated facades

• Izovol St-50 - density 50
• Izovol St-60 - density 60
• Izovol St-75 - density 75
• Izovol St-90 - density 90

Mineral wool laminated with canvas, as an outer layer of insulation in ventilated facades

• Isovol B-50 - density 50
• Izovol V-75 - density 75
• Izovol V-90 - density 90

• Izovol K-100
• Izovol K-120
• Izovol K-150
• Izovol K-175

The top layer of thermal insulation in flat roofs (KV - roof top)

Izovol produces the following types of insulating materials:

• General construction thermal insulation
• Soundproofing
• Technical thermal insulation
• Fire protection
• Thermal insulation for sandwich panels

Facilities where the plant's products were used. These are mainly the central regions and southern Russia, this is due to the location of the plant.

Not a single new building will last even ten years if it was built without the use of thermal insulation materials. Thanks to them, maximum heat savings are achieved, the absence of drafts and “cold bridges” inside the walls, and the service life declared by the manufacturers allows you to forget about major repairs of the building for decades.

Main types of Izovol insulation and scope of application

Izovol ST – has a medium density. It is used for insulation of hanging poorly ventilated structures, where it is necessary to create a gap between the facade and a layer of insulating material.

Izovol F - allows you to provide walls with reliable thermal insulation and sound insulation. Before starting to lay the insulation, the walls are carefully plastered and leveled.

Izovol KV – is characterized by high rigidity and increased resistance to moisture. Used for insulation of two-layer flat roofing.

Izovol L – has a low density, used in the manufacture of structures that may be subject to mechanical impact during operation. The material is used to insulate pitched roofs, frame walls, partitions and floors.

Izovol B – the slabs are additionally covered with fiberglass. They are most often used when carrying out work aimed at insulating the facades of buildings characterized by normal ventilation.

Izovol K - used for insulation of flat roofs.

Izovol P – is characterized by high rigidity and high resistance to moisture. The material is used for insulating basements and floors, including those equipped with a heating system.

Disadvantages of thermal insulation material

Alas, even isobel is not without its drawbacks, although there are not many of them. These include:

• the possibility of loss of thermal insulation properties in the places where the plates are joined or in the area of ​​contact with the sheathing (the joint is not sealed with sealant or foam, like polystyrene foam);
• an additional waterproofing layer is required, since if there is direct contact with water, the slab will swell and cease to be useful;
• a sheathing of a certain size is required (according to the dimensions of the izobel insulation boards);
• the process is complicated by the use of a mask, gloves and clothing covering the skin; otherwise, small particles falling off the slab will land on the skin, causing allergies or scabies.

Despite the minor disadvantages of isobel, the material is still recommended for use in almost any room. It is available, it is easy to cover an area of ​​the house with it, and the next replacement of insulation, if the installation technology is followed, will not have to be done earlier than in 50 years. When purchasing the material, the consumer will save a good amount, and during operation he will be convinced of the right choice.

Features of production technology

The Izovol company's product range includes basalt insulation - slabs, rolls, foil mats.
Izovol insulation is made from mountain basalt rocks. Modern equipment that meets state standards is used for production. First, the rock is melted to a liquid state in gas melting furnaces, which ensures the high quality of the resulting material.

The fibers undergo a centrifugation and blowing procedure, which makes it possible to achieve the correct shape of the insulation and its uniform density over the entire area. Air gaps remain between them, so the appearance of cold bridges is excluded. Mineral wool feels soft, hard or semi-hard to the touch. The material production process is fully automated.

Technical characteristics of Izobel thermal insulation

In the red package, the mineral wool density is 35 kg/m. cube

In principle, Isobel insulation is practically no different in technical characteristics from any other basalt thermal insulation. Despite the desires of each manufacturer to somehow distinguish their product from many competitors, the essence remains the same and Izobel insulation is no exception. The only thing that distinguishes it is its low price.

The cost of any stone wool depends on its density. Izobel thermal insulation in green packaging is the cheapest, as its density is only 25 kg/m. cube But Isobel P 75 has a density of 35 kg/m. cube, it comes in red packaging and is more expensive.

Isobel insulation, characteristics:

• flammability degree NG - does not burn;
• humidity of the supplied material (from its own weight) – 0.5%;
• ability to pass steam – 0.3 mg/m*h*Pa;
• thermal conductivity lambda – 0.036 W/m*K;
• moisture absorption - 1.5% per day when completely immersed in water.

The dimensions of the slabs for all Izobel thermal insulation lines are standard and are 1000x600 mm. Insulation with a density of 25 kg/m. cube (in green packaging) is available in thicknesses of 50, 75 and 100 mm, and the material has a density of 35 kg/m. cube (in red packaging) – only 50 mm.

Thermal insulation is only suitable for interior work. The lathing is needed so that Isobel does not sag under its own weight. According to the standard, when installing light basalt wool on the sheathing, horizontal strips are installed every 3 m. In this case, the laying step can be reduced to 2 m.

Despite the fact that the material is treated with water-repellent compounds during the production process, it still needs to be protected from moisture using films. For different types of work, waterproofing and vapor barrier are used. We described how to properly install waterproofing in one of the previous articles.

Main technical characteristics of ISOVOL products

Since ISOVOL insulation illustrates the technical characteristics on each package of the material, the buyer can independently, without the help of a consultant, select the most suitable type of heat insulator.

All ISOVOL materials are characterized by the following properties:

• stone wool (as IZOVOL products are sometimes called) absorbs noise and blocks the transmission of vertical sound waves;
• The environmental friendliness of the product allows it to be used in almost any work;
• ease of installation ensures a quick process of insulating residential buildings;
• a high level of fire resistance is very important when using materials in facilities with chemical compounds or explosive substances;
• the thermal technical efficiency of materials is formed due to low thermal conductivity (thermal resistance is achieved by creating a wall made of wood (0.25 m thick) or sand-lime brick (2 m thick));
• the service life of ISOVOL products reaches 50 years;
• resistance to acids, alkalis and solvents increases service life (this property also helps to avoid corrosion);
• The property of double action vapor permeability contributes to the rapid removal of all moisture from the room and evaporation from the surface of the material itself.

What types of Izovol are there?

Each type of insulation has its own characteristics and dimensions. The following describes the parameters of the most commonly used models.

Isobel

The density of such slabs is 25 kg/m3, in some models - 20 kg/m3. They are used on non-loaded inclined structures and on horizontal surfaces (floors on joists). At full immersion, volumetric water absorption is 1.5% and thermal conductivity is 0.036 W/mK.

Izovol ST

The mats are made from thin basalt fibers. They vary in their density. There are models with rates of 50, 60, 75 and 90 kg/m3. Water absorption of this material is up to 1%.

It is used for floors, sloping roofs and interior partitions. All insulation dimensions are indicated on the manufacturer’s website. This model has dimensions 100*60 cm.

Different thickness of insulation

Isovol B

This model is specially designed for insulation of ventilated facades and is finished with fiberglass. It contains a protective layer that prevents the basalt wool from being blown out and plays the role of wind protection. The density of this material is 50, 75 or 90 kg/m3. In addition to thermal insulation, it provides sound insulation and fire safety. Like all other types of Izovol, it has a flammability class of NG, that is, not flammable.

Plaster facades

Izovol F

It is used as a heat-insulating layer in façade systems with a plaster layer, and as fire-resistant cuts in structures using expanded polystyrene. The thickness of the material ranges from 4 to 25 cm. Isovol F has dimensions of 100*60 cm. The slabs are produced with a density of 100 to 150 kg/m3. They have high strength, water absorption at full immersion is 1% and thermal conductivity is 0.036-0.040 W/m K.

Izovol K

This model is used for insulating flat roofs, as a filler in reinforced concrete wall panels. One option for roof insulation is a two-layer system. If the first layer has a thickness of 10 cm or more, in this case it is best to use Isovol K. It is best to choose Izovol KV as the top layer.

A distinctive feature of this insulation is its almost square size: 100*120 cm - you can quickly cover large areas. This material has a density from 100 to 175 kg/m3. The thickness of the slabs ranges from 4 to 25 cm.

Thermal insulation of flat roofs

Izovol KV

Such slabs are used in single-layer and two-layer roof insulation systems. In the second option, a combination with Izovol K is used, it is placed on the bottom layer. If the thickness of the thermal insulation layer must be large, two layers of insulation are used. The advantage of this insulation is its increased rigidity and moisture resistance. This allows the material to be used for existing roofs. Such slabs perform not only thermal insulation, but also fire-fighting functions.

Izovol is a safe and reliable environmentally friendly non-flammable heat insulator

Izovol P

This material is used for thermal insulation of floors before concrete screeding, for flat roofs, as well as other areas with high humidity. Isovol P with a density of 175 kg/m3 can withstand a load of no more than 65 kPa, while the insulation does not deform. When using material with a density of 100 kg/m3, a load of up to 35 kPa is allowed.

When insulating the floor, the material has a soundproofing and fireproof effect. It is used to create heated or floating floors. Izovol P has standard dimensions of 100*60 cm. Other characteristics are similar to other series of material.

Izovol L

This model is used in various areas of insulation, horizontal and vertical. It is used for roofing, interior partitions, and attic floors. One of the special areas of application is the insulation of heating and ventilation systems, pipelines and refrigeration units.

Where is Isovol used?

IZOVOL
This material is widely used in individual construction and industrial purposes. From private use, the following areas of insulation can be noted:

• Facade with plaster coating
• Ventilated facade
• Three-layer masonry, where the middle layer is insulation
• Frame walls
• Foundation and floor
• Interfloor ceilings
• Pitched roof
• Technical insulation

In industrial construction, Izovol is used to create sandwich panels and insulate flat roofs in single- and double-layer coatings. Izovol KV-150 is produced in slabs up to 18 cm thick.
