Do-it-yourself floor insulation from foam glass crumbs. Nuances of using granulated foam glass

Foam glass belongs to durable, strong and popular materials for insulation. It is easy to install and high efficiency... The technology was invented almost a century ago in the USSR, and practical use came up later in Canada. Massively on the market of building materials, foam glass appeared recently, when the technology of its production made it possible to make it affordable and of high quality. Before using, it is worth considering what granules or plates of foam glass are, their main advantages and disadvantages, as well as methods of use for insulation.

Foam glass combines the advantages of two materials at once. It combines silicate glass, which is strong and brittle, and foam, an incredibly lightweight material. The production of foam glass consists in heating the silicate mass with the addition of a substance that forms a gas. The high temperature leads to the melting of the substance, as well as the formation of small bubbles. This technology makes it possible to obtain a lightweight and durable material that has a high heat resistance.

In the field of thermal insulation, two main types are used:

Slab foam glass. The insulation is in the form of a slab, which has a structure with closed cells. Ideal for insulating basements, façades, ceilings, ceilings and foundations. The thickness is 6-12 cm, and the size of the slab is 45 * 60 cm. They can withstand even significant operational loads, do not shrink and are resistant to deformation under mechanical stress.

Plate insulation

Granular material. Represents microporous spherical granules. It is produced in granules of various sizes from 1-5 mm to 7-20 mm. Can be used as insulation for interior walls, ceilings and floors.

Granulated foam glass

The technical characteristics of the two types of material are similar, therefore, when choosing it, one should rely only on the convenience and expediency of using a heater of one form or another.

Main characteristics

According to statistics, the higher the hardness of the material, the lower its thermal insulation properties. Foam glass belongs to heaters that not only withstand serious loads, but also have a low thermal conductivity.

Other material characteristics include:

Thermal conductivity. Foam glass has a thermal conductivity of 0.04 W / m * s. If we compare it with wood, then this material has this indicator twice as low, while minimum wool higher by an average of 25%. Therefore, foam glass perfectly protects against heat loss. better than wood, mineral wool and many other heaters. High thermal insulation properties are explained by the presence of small closed cells with thin partitions in the structure.
Strength. Square meter insulation is able to withstand a pressure of 40-100 tons, and the strength indicator is 0.5-1.2 MPa. This indicator does not deteriorate over time. However, the impact strength of the material is low. Foam glass can be broken by strong mechanical stress.
Soundproofing. Foam glass is effectively used not only to protect against heat loss, but also from extraneous noise. The material is capable of damping sound waves with a force of 45-56 decibels.
Resistant to temperatures. The insulation is able to withstand temperatures from -200 to +300 degrees, which allows it to be used even at extreme temperatures.
Density. This indicator for the material is very low and is equal to 100-250 kg per cubic meter. And this figure is at least three times lower than the density of the tree.
Water vapor permeability. Foam glass can also be used as a vapor barrier. The vapor permeability index is only 0.005 mg / (m * h * Pa).
Moisture resistance. Plates and granules of foam glass are capable of absorbing no more than 2% of their own volume of water. The material not only does not absorb moisture, but also does not change its properties when interacting with it.

High moisture resistance

Biological stability. Foam glass has a high resistance to insects, rodents and microorganisms. Insulation does not absorb water, so mold and mildew do not form in it. And the high hardness of the material protects it from insects and rodents.
Chemical resistance. Foam glass is a chemically inert material. Therefore, in contact with acids, alkalis, gases and oil products, foam glass does not interact. The only substance that the foam glass interacts with is hydrofluoric acid.
Ecological cleanliness. Foam glass does not burn, does not emit toxic gases and does not produce decomposition products. This makes the material safe for the insulation of living quarters.

The unique characteristics of the material are due to the combination of the properties of silicate glass and gas microcapsules.

Main advantages

The use of foam glass as a heater has a number of significant advantages. These include:

Excellent thermal insulation characteristics... They are explained by the peculiarity of the structure of the material - small closed cells with thin partitions.
Versatility. The material is versatile, therefore it can be used to insulate facades, roofs, foundations, communications, walls and floors. It can be used even for objects with a high fire hazard rate.
Long service life. The material can last more than 100 years without loss performance... At the same time, it tolerates high and low temperatures well, as well as their sharp drops.
Good sound insulation properties. A layer of insulation of 10 cm is able to drown out even the sounds of a working tractor engine behind the wall. Therefore, the material is effectively used not only to protect against heat loss, but also from extraneous noise.
Ease of installation. An ordinary hacksaw can be used to cut the slabs; it is enough to simply pour the granules onto the prepared surfaces. The material is incredibly lightweight, so it's easy to work with.
Safety. The material does not emit hazardous compounds, therefore it can be used in public and residential premises.
Non-flammability. Foam glass does not burn, and at very high temperatures it only melts without emitting toxic components and smoke.

The advantages of foam glass made it one of the most successful and quality materials for insulation of floors, roofs, ceilings, basements, walls and other surfaces.

Main disadvantages

Despite the obvious advantages of foam glass, when choosing it as a heater, disadvantages should also be taken into account. These include:

High price. In the building materials market, foam glass is one of the most expensive insulation materials. This is due to the high energy consumption during production. In addition, expensive equipment is required for manufacturing.
Low impact strength. The material has a high compressive strength, but it is quite brittle material. Therefore, with strong impacts, the foam glass can crack, and such cracked slabs can no longer be used as insulation.
Low steam permeability. This property of the material is both its advantage and disadvantage. Despite the fact that fungi and mold cannot form in the foam glass, the surface that it covers does not exchange air, therefore, foci of infection may appear.

Foam glass - high quality and modern insulation for different types surface, however, when choosing it, disadvantages should also be taken into account.

Details of home insulation with foam glass can be found in the video:

Application

A feature of the material is its excellent thermal insulation properties combined with high strength. Therefore, it can be used to insulate the basement, foundation, load-bearing walls and pipelines. The low rate of water absorption allows it to be used for thermal insulation of the basement, foundation and basement floor... Granular material can be used as a thermal insulation additive for concrete. For thermal insulation of walls, it is enough to fill it in their cavities.

Thermal insulation with granular foam glass

Foam glass is well cut and drilled, so it is easy to make pieces of the desired size from the plates. In addition, the boards hold plaster, putty, glue and other surface finishing compounds well.

The material can be used not only for residential and public spaces. It is used for housings of various technological and industrial equipment that operate at high temperatures.

Foam glass insulation

Foam glass insulation technology

In order to guarantee high thermal insulation qualities of the material, it is required to observe the technology of its installation:

For fixing the boards, it is recommended to use special glue, which must be applied to reverse side slabs and side walls. After that, the glue should be evenly distributed over the surface of the sheet.
If the surface has pits, bumps or other irregularities, the adhesive should be applied to the foam glass with slaps in order to obtain the most even base.
When insulating a wooden base, it is recommended to fix the slabs with special dowels. The tree expands when exposed to moisture and temperature, therefore, the insulation to it must be mounted mechanically.
When installing the slab on a vertical surface, it is necessary to install the lower bar, using building level... It is best to use a metal profile or rail as a strip.
The first row of insulation should be mounted on a profile that will act as a support. After the glue has completely set, the support can be removed. However, it is best to remove it after the work is complete.
When installing slabs on vertical or inclined surfaces, start from the bottom, and on horizontal surfaces - from the far corner.
Plates should be laid close to each other with one row offset relative to the other. After application and complete drying of the glue, it is additionally recommended to reinforce the boards with special dowels.
Around windows and doors thermal insulation boards it is recommended to mount in solid figures. It is not allowed to connect separate pieces of material to each other on corner lines.

Roof insulation with foam glass

The foam glass is high quality, modern and very light material for thermal insulation different surfaces... Competent adherence to the installation technology will improve the efficiency of thermal insulation and extend the life of the material.

Foam glass is rightfully considered one of the highest quality and most durable thermal insulation materials. Due to its truly unique characteristics, this material has found its application not only in individual construction, but even in the construction of industrial facilities. However, with all its advantages, the insulator is not so popular in comparison with other heat insulators, and there are reasons for this. In addition to a lot of positive properties and characteristics, foam glass also has significant disadvantages. Let's see what disadvantages of foam glass prevent it from becoming the first among

Expensive production

The problem is that cheap raw materials such as shards are used to produce this material. broken glass or sintered rocks, but the manufacturing technology itself is quite expensive. In order to obtain granulated foam glass, a temperature of the order of 800-900 degrees and molds made of heat-resistant steel are required.

The manufacturing process consists first in heating and softening the glass powder obtained from the raw material.
Then it is foamed due to the combustion of a gas generator - as a rule, it is coal.
After the material is slowly cooled, the result is foam glass.

The production of insulation is a rather complex and long process, due to which the cost of seemingly cheap raw materials increases significantly.

Foam glass products

The end result of production is blocks with a cellular structure and granulated foam glass. Through the application special forms block products have a higher cost than the same volume of material in the form of granules.

Subsequently, the blocks are cut into slabs, which are used as thermal insulation in complex objects. For example, on roofs with large area or complex structures geometric shape, as well as for thermal insulation of underground structures. It is convenient to use a foam glass plate as thermal insulation for swimming pools, bathtubs and other buildings in which a complex temperature regime is operated, and all due to the special resistance of the material to the effects of water vapor.

Granulated foam glass is used, as a rule, as bulk free thermal insulation on roofs or as a backfill under a screed. The second use of this material is as a filler for various solutions to obtain light screeds, plasters or foundation blocks.

Both products have the composition and characteristics of ordinary glass, therefore the advantages and disadvantages of foam glass are based on the properties of this material.

Strength properties of foam glass

This insulation is one of the most durable of all types of thermal insulation. However, we are talking only about the compressive strength, which is important for heat-insulating materials, since it is this load that the insulator, as a rule, is subjected to. The special value of this parameter is due to the fact that with strong compression, the insulation can lose some of its properties: its moisture resistance is violated, and the insulator begins to conduct heat.

Unlike foam and fibrous materials, which are designed for only small internal forces, which significantly limits their use in some situations, foam glass is absolutely not compressible, and this allows it to take on some of the loads.

Resistance to deformation

Foam glass does not deform under the influence of gravity, which prevents it from sagging, shrinking or shrinking. Thanks to this, the insulation does not require mandatory fastening to metal anchors or pins, which can create cold bridges. The material can be easily glued on hot bitumen, polymer or concrete mastics and specialized adhesives.

But not all the strength characteristics of the insulation are so ideal. The disadvantages of foam glass are based primarily on the properties of the original raw material, which has a low resistance to mechanical shock. Therefore, the blocks are quite easy to break or damage. And even small defects surfaces can lead to a decrease in moisture resistance and an increase in thermal conductivity.

Service life of foam glass

The service life of the insulation is at least 100 years, which significantly exceeds the service life of most buildings without overhaul where its application is possible.

Foam glass was created back in the 30s of the last century, so today we can talk about the resistance to aging of this material. Experimental studies have been carried out by experts, which have shown that foam glass blocks have not lost their properties over an interval of 50 years and have remained practically unchanged.

However, this advantage is irrelevant in private construction, since low-rise buildings need reconstruction no later than 50 years later. Therefore, it is more advisable to use, although less durable, but cheaper heat-insulating materials than to use foam glass, the price of which is quite high (16,000 rubles / m 3).

Resistant to environmental influences

In this case in question about various kinds of impacts of both chemical and biological nature. Thermal insulation materials made of foam glass are not destroyed chemicals, the only exception is But this can hardly be considered a disadvantage, since this reagent can be found only in the chemical industry.

Since foam glass consists only of various elements, it is not affected by the oxygen contained in the surrounding air, and therefore oxidized.

Thanks to the same feature, the insulation is not subject to combustion. When exposed to high temperatures, it melts like ordinary glass, while not emitting, unlike most heat-insulating materials, harmful gases and substances.

There is another factor that affects the fire safety of the material - the lack of absorbency. Foam glass fully possesses this property and is not an absorbent material.

Non-hygroscopicity of the material

Thanks to this characteristic, it has no effect on the insulation and water, no matter whether it is fresh or salty, since there are no soluble components in the composition, and the structure of the foam glass is closed cells into which moisture is simply not able to get into. Thanks to these qualities, the material does not collapse under the action low temperatures... Therefore, insulation is often used as

In addition, foam glass, whose characteristics are identical to those of ordinary glass, has a low coefficient of thermal expansion, which means that it can withstand seasonal temperature changes without problems, regardless of the region of use. Another positive property of the material is high-quality sound insulation, and all thanks to the dense structure of the foam glass.

Foam glass FOAMGLAS

However, the non-hygroscopicity and density of the material also causes some disadvantages of foam glass, in particular, its rather large weight in comparison with other heat insulators. This significantly complicates the transportation of the insulation, which significantly increases the selling price of the material. And installation is becoming a rather problematic event.

However, it allows us to correct this shortcoming as well. For example, the Pittsburg Corning corporation produces FOAMGLAS foam glass, which is extremely lightweight, while retaining all the properties inherent in this material.

Therefore, today foam glass is mainly mounted on building mixtures, which simplifies the fastening of the insulation. In addition, good adhesion of the material is also due to the good adhesion of the foam glass.

Biological impact

First of all, we note that the foam glass is absolutely resistant to decay, the formation of mold and fungi, since it is simply absent in its composition. favorable environment for their reproduction. This factor is especially important in construction, when thermal insulation materials are often used in confined spaces. A similar property of foam glass allows you to guaranteed to avoid the destruction of both the heat insulator and the surface that it protects, be it a roof, a wall or a foundation.

It is also important that the foam glass cannot be damaged by plant roots. And also absolutely inaccessible for the penetration of insects and rodents, due to its abrasive properties. This feature of the material has found its application in the arrangement of granaries, warehouses and food refrigeration rooms, when foam glass insulation is also an ideal protection against various biological forms.

What other advantages and disadvantages do foam glass have?

In addition to the main characteristics listed above, the material has several more distinctive properties.

Foam glass is very easy to process and give it the desired shape using conventional cutting tools... This allows this insulator to be used for buildings of any geometric shape. But the industrial production of blocks is a rather complex process, leading to a significant increase in the cost of the material.

Insulation foam glass is an absolutely environmentally friendly material that does not have any harmful effects on human health. And more recently, it was produced using a technology where hydrogen sulfide was used as a gas generator. Its smell was transferred to the finished material, therefore the use of insulation in private construction was rather limited due to bad smell"Rotten eggs".

Due to its environmental friendliness, foam glass is becoming one of the most popular thermal insulation materials today, and after use, the insulation can be once again processed into a new product.

One of best warm and soundproof materials is foam glass. This insulation was created by Soviet scientists in the 30s, but due to the high cost and imperfect manufacturing technology, it did not receive widespread... Three decades later, the Canadians found practical use for it, where foam glass was used as thermal insulation for a building. This material entered mass construction relatively recently, when all the shortcomings were taken into account and the production costs were reduced. The article will focus on how to insulate with foam glass.

What is foam glass

This inorganic thermal insulation material has a porous structure. During the production process, the molten glass is heated under high temperatures, the added gas-forming substance forms bubbles with a diameter from a millimeter to a centimeter. The porosity ranges from 80-95%.

Foam glass photo

The color of the products can be different: cream, green or black. This property depends on the raw material, because crushed quartz, sodium sulfate, sedimentary rocks, and irrecoverable cullet are used in production.
Insulation is offered in the form of granules, slabs and fittings (pipe shells). Foam glass blocks are popular, which can be of the following sizes:
- length - 200, 250, 400, 475 mm;
- width - 125, 200, 250, 400 mm;
- thickness - 80,100, 120 mm.
Installation is carried out by means of mechanical fasteners, cement mortars, mastics and other adhesives. The fixing method is chosen depending on the type of surface (concrete, iron, wood).

Foam glass characteristics

It is a lightweight material with a density of 120-200 kg / m. cub.
As for the ultimate compressive strength, this indicator is very high and varies from 0.5 to 1.2 MPa.
Thermal conductivity is even better than that of wood - 0.06 W / m * s versus 0.09 W / m * s, respectively.
The absorption index of sound waves for a 100 mm thick slab is 50 dB, which provides increased comfort.

The amount of sorption is negligible and does not exceed 4% of the volume.
The temperature range for the use of the material is very wide - from -200 to + 500C. At a higher temperature (from + 540C), the plates begin to deform, but do not emit toxic gases or vapors. Heat resistance makes it possible to use foam glass at facilities that are subject to increased fire safety requirements.
Chemical inertness is high. The material does not interact with acids, alkalis, oil products and other aggressive media.

Benefits of using foam glass

In addition to high physical and technical characteristics, among the advantages can be noted the absolute ecological purity. The material is recommended for use in buildings with increased requirements for sanitary and hygienic conditions.
The mats do not change their size during the entire period of service. Glass cells do not deform under operational loads and seasonal temperature changes. Thus, the formation of cold bridges due to compression, sagging, swelling or shrinkage is not allowed.

Foam glass is not subject to decay and the development of corrosive processes. Also, it is not attractive to microorganisms, molds, fungi and rodents, which indicates biological resistance. Due to the above advantages, the service life of the units is at least 100 years.
The thermal insulation material is easy to process. It can be cut, drilled and sawed without crumbs or cracks. It can be combined with almost all types of building materials: cement, brick, iron surfaces, holds finishing compounds well.

Disadvantages of foam glass insulation

The main disadvantage is the high cost, because the manufacturing process itself is a complex technological problem. For the production of insulation in the form of a shell, it is required optional equipment, which entails an increase in the cost of the finished product.
One more drawback can be noted - low resistance to shock loads. But this indicator is not critical, since the insulation is not subjected to such tests.

Attention! "Analogs"

More than cheap analog, which is made of liquid glass. Ready product does not differ in strength and moisture resistance. At its core, it is a porous glue.
The only plus of this material is its low cost, which can be 2 or even 3 times less than that of foam glass products made from solid raw materials.

Foam glass application

Due to its heat-insulating properties, the material is used:

in civil engineering. It is widely used for thermal insulation engineering communications... This material is used to equip "warm floors", exploited roofs, attics, basements, foundations. They also insulate the inner and outer walls;

in sports facilities. Blocky and granular material It is widely used in the construction of ice arenas, swimming pools, playgrounds and other facilities to which special requirements are imposed;
in industrial facilities. Foamed glass melt works to reduce operating costs due to high thermal resistance... Therefore, its application is relevant not only for ground, but also underground structures, such as: buried reservoirs and other containers;
in national economy... Crushed stone from foam glass makes it possible to erect buildings on clay and waterlogged soils. It provides reliable thermal insulation for farms intended for breeding poultry, cattle, etc.

in beautification household territories... Foam glass bulk material has found its application in the arrangement of greenhouses and hotbeds. Performance characteristics allow you to form the relief on the site, equip pedestrian paths, create gabions, use in drainage systems and groundwater outlets. They also insulate buried containers.

Improving efficiency

When choosing the thickness of the slabs, it is necessary to take into account the thermal insulation properties of the material used for the construction of the house. So for external insulation of brick, concrete and silicate walls foam glass plates with a thickness of 120 mm are used.
For buildings made of wood, foam and expanded clay concrete blocks, this heat-insulating material with a thickness of 80-100 mm is suitable.
Internal insulation works are carried out by means of 60 mm thick foamed glass melt. Plates are fixed with adhesives, thin dowels and steel L-shaped brackets.

For the "warm floor" system, foundation and interfloor (attic) floors, granular material is used. It will fill all voids and provide the necessary thermal insulation. The calculation of the layer thickness is based on temperature conditions region of residence.

Installation of foam glass

For fixing the mats, a special foam glass glue is used. It is applied to the back and 2 side walls. Cement-containing mortars and bitumen-based compounds are evenly distributed around the perimeter.
If there are slight bulges or depressions on the surface, then it is recommended to apply the adhesive mixture to the foam glass with “slaps” (at least 5 pieces per plate). With this method, the consumption of glue will increase, but the base will become as even as possible.
For wooden surfaces use special dowels. This is because wood is subject to thermal expansion. In this connection, the plates must be fixed mechanically, which will allow the foam glass blocks to "move" after the tree.
Before installing the boards on vertical surfaces, a horizontal strip is installed at the level of the basement under the level. It can be a bar or a metal profile, if necessary, wedges are placed between the base and the rail. The empty space is filled with foam.
The first row of insulation is installed on a profile that acts as a support. After the adhesive has hardened, the support is dismantled. For reliability, it is better to remove the horizontal bar upon completion of all work.

Foam glass mats are mounted on walls and sloped roofs from bottom to top, on horizontal surfaces(for example, on interfloor ceilings, foundations) in the direction - "towards yourself", that is, from the far corner.
Laying of foam glass products is carried out close to each other with the obligatory displacement of one row relative to the other (with bandaging of the seams). If, in addition to glue, it is planned to additionally use dowels, then their fasteners are made after the binder mixture has completely dried.
Thermal insulation boards around window or door openings, chimneys and other elements are mounted in solid pieces. Docking of foamed molten glass blocks on corner lines is not allowed.

Foam glass stacking technology

Knowing the method of fastening this material, you can quickly and easily carry out the insulation of any objects under construction. Proper placement of all layers will help improve the effectiveness of thermal insulation.

Unique physical and technical properties make it possible to reduce the thickness of the "cake" and to abandon the use of wind and moisture protection membranes. Below is the most common use of foam glass panels.

Heavy cladding wall... Products made of foamed glass melt are glued to a reinforced concrete or brick surface. Additional fixation is performed mechanically (4-5 dowels per plate). After the entire perimeter has been laid, they switch to the installation of a metal profile designed for facing stone... This option is also applicable for arranging the basement.

Plaster wall... Foam glass mats are attached to brickwork or walls erected from foam or aerated concrete blocks using an adhesive composition. Before applying the finishing material, the boards are covered with an overlap mesh (at least 100 mm). It is fixed with disc dowels with pressure washers. The thickness of the plaster layer can be up to 30 mm.
Wall with facing bricks... The brick base is pasted over with foam glass plates. It is more convenient to insert flexible connections after the insulation is laid, and not before its installation. Next, a facing brick masonry is erected. Here you can also use granular material, which is poured between the main and the facing wall as the latter is being erected (the distance between the masonry is at least 250 mm).
Wall for profiled sheet... Wall surfaces are covered with foam glass mats. On top of them, a crate of wooden slats or a metal profile. Fasteners are selected depending on the material from which the walls are erected. Profiled sheets are installed according to the appropriate technology (from bottom to top and from left to right, with an overlap along the horizontal and vertical level).

Internal walls (partitions)... Indoor work is not much different from outdoor installation of the presented insulation. Insulation is also attached to the surface, which is covered with a layer of plaster (you can mount the profile under drywall sheets).
Roof under roll materials ... The reinforced concrete slab, if necessary, is covered with a bitumen-polymer primer, which provides high level moisture protection. Next, a hot bitumen-based mastic or glue solution is applied to the foam glass block and fixed on the surface with slight pressure. The finished fabric is treated with hot bitumen. With the help of a torch, an EPP waterproofing layer is fused, and then a roll material of the EKP type.

Roof with a slight slope for sheet coverings... Overlapping from reinforced concrete foam glass blocks are glued. You can use special adhesives or bituminous mastics... Upon completion of the work, the foam glass surface is covered with a hot bitumen-polymer mass. To increase the waterproofing of the roof, fused roll materials are used. After hardening, a lathing is performed that corresponds to one or another roofing material.
Wooden roof... The rafters are equipped with a continuous flooring. On top of it, a layer of waterproofing materials on a bitumen basis is spread, the fastening of which is carried out mechanically. Next, the foam glass is mounted, then the waterproofing material. Now the surface is completely ready for laying any roofing material.
Insulation of floors with foam glass... Foam glass plates are laid out tightly on top concrete base or a compacted layer of sand or cement. Here, the thickness of the slab will depend on the expected loads. Next, polyethylene is laid in 2 layers, and then the whole cake is poured with a sand-cement mixture. This base is completely ready for arrangement with various finishing materials: linoleum, parquet, ceramic tiles etc.

Foam glass products have the characteristics necessary for effective thermal insulation of buildings for any purpose. They combine: low heat transfer rates, ease of installation, long service life, fire and biological resistance, environmental Safety both for man and structure.

Despite the high cost of this material, laying foam glass will pay off all costs due to the absence of additional layers of the pie and due to the minimum amounts in heating bills.

Application of Granular Foam Glass in Individual Construction

Everyone dreams of making their home a real fortress, and the latest building and insulation materials, which can significantly increase the heat engineering parameters of the structural elements performed and improve the microclimate during indoor areas residential building. Many building elements need insulation, a unique set of properties granulated foam glass allows you to use this material widely enough.

Usage granulated foam glass in individual construction, it allows to create energy-saving buildings much lighter than conventional ones, reducing the cost of construction by 20 - 25%; it is used as a heat-insulating material in the construction of cottages, summer cottages and other residential premises, since it does not emit harmful substances in operation and environmentally friendly. It should be noted that this type of ezolation is suitable for rooms with special requirements for humidity (baths, saunas, basements).

Granulated foam glass has a unique strength-to-density ratio. No other mineral porous material has such a high compressive strength (without any deformation !!) at a low density; low thermal conductivity, absolute non-combustibility, ease of handling and installation.

Consider the features of insulation on some examples.

Insulation of the foundation

It should be noted that a lot of heat is lost precisely through the foundation, if it is not insulated. To exclude various accidents that can negatively affect the structure, there is the most reliable type of foundation: slab monolithic, which is a thick reinforced concrete slab reinforced in two layers. Insulation of such a foundation with granular foam glass allows not only to reduce heat loss through the floor of the first floor, but also to avoid uneven subsidence of the foundation. The high strength of granulated foam glass allows for pouring foundation slab on a layer of compacted gravel.

Wall insulation.

One of the particular solutions for constructions of multi-layer walls is an effective well brickwork. Insulated well brickwork consists of three layers: outer and inner walls, rigidly interconnected by vertical diaphragms made of masonry bricks, and a layer of wall insulation located between them. When erecting diaphragms, a distance is left between the bricks of the diaphragm, which is later filled with bulk thermal insulation - granular foam glass... It easily fills masonry wells different forms with obtaining a uniform backfill.

Due to the complete absence of organic matter, granulated foam glass does not contain a nutrient medium for flora and fauna, including microorganisms. Thus, the foam glass cannot be eaten by rodents and mold will not form on it.

Floor insulation.

If timely thermal insulation of the floor is not carried out, or the floor is poorly insulated, heat loss through the floor will be the norm. The floors carry high static and dynamic loads, therefore, the insulation should be calculated so that the heat loss through the floor is reduced. For floors, it is better to use a heat-insulating material that has high compressive strength and almost no problems with deformation.

The high strength of the foam glass allows you to get an even and rigid base, this factor significantly increases the service life of the floor thermal insulation system. Foam glass has a number of unique features, which makes it possible to use it as a heater for wooden and concrete floors in various living quarters, a chemically resistant material, which is especially important when insulating a wooden floor on the first floor, insulating a concrete floor, insulating a floor in a bath.

Roof (roof) insulation.

The roof is one of the most moisture-prone elements of a home.

IN In this case, the best insulation is granular foam glass. Flat roofs are more popular today. Many designs take into account roofs and architectural solutions, exploiting options like “ winter gardens», Cafes, outdoor terraces.

When insulating a flat roof, granular foam glass can simultaneously act as a heat-insulating and sloping layer.
Flat roof experiences greater snow loads than pitched, since it is absent rafter system and the load is transferred directly to the floor. Low density of foam glass, combined with high strength, can significantly reduce these loads. At the same time, the layer of foam glass required for effective thermal insulation will be significantly less in comparison with the same expanded clay. The high drainage properties of the granular foam glass layer in combination with the low water absorption of the granules themselves make it possible to avoid the main problem of the inversion roof - the accumulation and freezing of moisture in the insulation layer. With thermal insulation pitched roof granulated foam glass is poured between the rafters, which also reduces the load on the supporting elements and significantly increases the service life of the structure.

Insulation of floors.

Depending on the location of the overlap, there are attic, interfloor, basement and basement. When insulating floors with granular foam glass, a boardwalk can act as a subfloor; when insulating the floor on logs / beams cement-sand screed, prefabricated floor systems. To insulate unattended premises, for example, unexploited attics, the backfill can remain free.
The use of foam glass in private housing construction when insulating floors will provide increased comfort due to its sound-absorbing properties. The ecology of the house is also important, which is increasingly being given increased attention and foam glass perfectly meets all the requirements of "cleanliness".

Pool insulation.

When building a pool, its thermal insulation plays a key role, because the main problem of such structures located on open area, is a great loss of heat. In this regard, the question arises: How to insulate the pool in order to avoid excessive rapid cooling water?

The pool will only be built correctly if all the conditions for its operation are met and provided reliable protection from heat loss. Of particular importance in this regard is the pool bowl. Due to the fact that it is located directly on the ground, it is necessary to insulate it with materials that have a high coefficient of heat resistance. average temperature the soil is about 5-7 degrees, while the water temperature in the pool is more than 25 degrees. Taking into account the fact that heat is trying to penetrate into cold zones, it is necessary to insulate the pool bowl even before the start of installation work.

Landscape design(garden sidewalk paths)

The purpose of the garden paths is the ability to go to the desired place without losses for planting, especially in rainy weather.Functional and convenient - such qualities can rightfully be given garden paths... If the Romans had beautifully laid paths in the gardens, and the Japanese generally endowed such paths with a special meaning, now paved paths emphasize the attractiveness flower beds, greenhouses, linking together different areas and its buildings.

You must clearly know which paths will play a leading role, and which ones are of secondary importance, their size and the material that is chosen for paving depends on this. So, in order for the car to enter the garage, you need a track that can withstand maximum loads, which means you need to thinkabout fundamental gain.Secondary paths can be made smaller in width. Here granular foam glass with its unique properties and characteristics will come to your aid.

We looked at several examples of use Granular foam glass in individual construction. Granulated foam glass is a relatively new insulation in the modern building materials market. When studying and comparing physical characteristics learned building material, we can say that the main advantages are high thermal insulation, not susceptibility to temporary destruction, environmental safety, resistance to aggressive media, moisture resistance, high adhesion, incombustibility and high mechanical stability at low density.

We can confidently say that this material is the future!

Cullet

Granulated foam glass produced in the form of particles having a close to spherical shape. The production is based on the foaming of individual, pre-rounded semi-finished granules in a rotary continuous furnace.

Slab foam glass are obtained by foaming blanks in continuous tunnel ovens. At the exit, the material is sent for long-term annealing and then to a sawing machine to give the plates accurate geometric dimensions.

Roof insulation

Cullet

In Russia, at least 5 million tons of glass are produced annually only in solid household waste. Foam glass production is a way of converting cullet from landfills into a highly efficient, energy-saving material.

Production of granulated foam glass

Granulated foam glass produced in the form of particles having a close to spherical shape. Production is based on foaming of individual, pre-rounded granules- semi-finished products in a rotary continuous kiln.

Production of plate glass

Slab foam glass get foaming of workpieces in passage tunnels ovens ... At the exit, the material is sent for long-term annealing and then to a sawing machine to give the plates accurate geometric dimensions.

Thermal insulation of horizontal surfaces

Granular foam glass easily fills any irregularities, can serve not only as a heat insulator, but also as a slope

Thermal insulation of vertical surfaces

Granular foam glass fills any cavities and creates reliable thermal insulation.

Roof insulation

Slab foam glass is irreplaceable tough, waterproof, durable thermal insulation material for roof insulation.

Thermal insulation of technological equipment

All over the world, slab foam glass is used at facilities where compromise is unacceptable - nuclear power plants, submarines, production facilities, etc.
