The AlStroy company sells three-layer wall blocks at a price that is the best in Russia. Houses built from three-layer blocks are quickly built, warm and durable. Such material appeared on the market some 15 years ago, but already in every locality In Russia you can find houses built from heat blocks. What is a three-layer block? This unique wall block was invented within the walls of the Leshchinikov Research Institute at the beginning of this century. Its uniqueness lies in innovative technology, allowing for construction site avoid two labor-intensive and expensive operations - insulation and facing works. Within two weeks, a team of masons erects a fully insulated and lined structure with an area of ​​150 m2. Previously, construction did not know such an intensive pace of building construction. Today, anyone can become the owner of a warm and beautiful stone home in a couple of months. Three-layer wall blocks received several synonymous names: thermally efficient, multilayer, three-layer block, as well as polyblock. The stone-insulating “sandwich” consists of three layers: façade, insulation, load-bearing.

Price: from 104 rub. Order

We offer buy three-layer blocks in 12 front versions. Such a number of textures and colors will allow you to implement any exterior solution!

The AlStroy company sells heat blocks in two sizes:

The first - 400 x 400 x 190 mm is suitable for the construction of buildings up to 4 floors high. The facade layer in it is 7 cm, the insulating layer is 18 cm, and the base, load-bearing layer is 15. The heat insulator is dense (M 25) foam plastic, securely fixed between the outer expanded clay concrete layers with four six-millimeter (in diameter) rods made of basalt plastic. The connecting pins are designed for a breaking load of 4 tons! The second type of three-layer thermal wall blocks has the following dimensions - 300 x 400 x 190 mm. They are used for one-story construction and during the completion of buildings. The dimensions of the layers here are somewhat different - the load-bearing and insulating layers are 120 mm each, and the façade layer is 60 mm. It should be noted that a slight decrease in the thickness of each layer of three-layer expanded clay concrete blocks does not in any way affect the heat-saving characteristics of the material - its energy efficiency margin is quite high.

The laying of these stones is carried out using traditional mortar, glue or a mixture thereof, taken in a ratio of 5:1. Minor deviation linear dimensions three-layer building blocks, only +/- 1.5 mm per side, allow small vertical (0.6 cm) and horizontal (0.8 cm) seams. To avoid the occurrence of cold bridges, all vertical seams across the width of the insulation are filled with special foam.
The tensile strength of masonry three-layer heat-efficient blocks under central compression is 140 kgf/cm2!

So should you buy three-layer blocks for construction?

Among the people, another name has been assigned to this building material - “miracle brick”. After all, one could only dream of a warm, prefabricated house before. Today, it is enough to read reviews about three-layer blocks to understand that such structures really are:

• environmentally friendly;
• do not ignite or support combustion;
• cheaper than traditional stone ones;
• highly thermally efficient.

We guarantee this building material for at least 50 years. But since in Europe expanded clay concrete houses more than 100 years old, we are sure that housing built from our three-layer thermally efficient wall blocks will last no less. And if you want to build just such a family nest, buy inexpensive three-layer blocks. Call us at any time, find out about the cost of three-layer blocks and the price of a cottage that we are ready to build for you at any time of the year - even this is possible with a thermal wall.

Price of three-layer blocks

Our three-layer block, the price of which is perhaps the most attractive in Russia, will allow you to minimize construction estimate. Purchasing high-quality three-layer blocks for building a house from the manufacturer will result in savings for the developer not only during the construction of housing, but also during its further operation. The absence of two additional operations (insulation and cladding) will lead to the fact that the cost of a house made of three-layer blocks will be more than 40% less compared to a traditional brick structure.

Wholesale purchase of polyblocks will cost up to 30% less than the purchase of gas-foam blocks, bricks and insulation. In addition, the cost of work to improve the facade and insulate the building will also add a considerable amount to the final construction estimate in the classic way. Cladding blocks, the price of which is affordable for the average developer, will significantly save money on delivery - instead of bringing building materials three times, it is enough to do it once. The AlStroy company sells heating blocks to all regions of Russia and organizes their delivery! For masonry warm stone no additional special equipment is required, which is a significant savings column.

Is it good to have a house made of three-layer blocks?

Three-layer walls made of blocks have confirmed in practice that a more thermally efficient material does not yet exist. In conditions of constantly rising heating costs, such buildings store heat 4 times more during the cold season than a conventional one stone house. And in summer they remain pleasantly cool. Savings on heating a home built from standard wall blocks with insulation is 30-35%.! Insulated brick house It will completely cool down in 3-4 days, and a building made of polyblocks will need 2 whole weeks.

Houses made from this material allow you to save up to 15% on laying a strip foundation. Under multi-layer walls, a base with a maximum width of 50 cm is installed (block thickness plus 10 cm), while under a standard insulated and tiled building you will need a foundation 60-70 cm wide.

In addition, three-layer blocks for construction are classified as lightweight building materials. This allows the installation of foundation pillars, which saves the developer even more money. Compared to the classic construction of insulated housing, labor costs during the construction of a polyblock building will be reduced by 30-35%. After all, the need to insulate and clad the façade in this case simply disappears. Well, one last thing. Three-layer thermally efficient wall blocks will be “gifted” to the developer extra room! If we compare usable area standard, 140 m2 brick, and the same multi-layer block housing, it turns out that the second is 14 m2 more spacious. Narrower (but also warmer) walls will increase living space by 10%.

Construction of a country house from modern heat-efficient ceramic blocks is economically less expensive than from products called heat blocks, sometimes also called heat walls or thermoblocks. Below, using the example of our house project shown on the left, a comparative cost calculation is shown.

The final costs when choosing thermally efficient ceramic blocks Cayman30 will be lower by 162,697 rubles.

When choosing a building material, responsible structures should be understood.
The difference between full-fledged production and artisanal production is the level of responsibility. You can be responsible for something specific. When it comes to building materials, this is of course technical characteristics of the manufactured product. Specifications can be declared by submitting your product to independent professional laboratories that have everything necessary to carry out tests, the result of which is test reports.

Load-bearing wall materials are used in the most critical home structures. Moreover, the blocks of load-bearing walls are not wallpaper, and if you make a mistake with the choice, you will no longer be able to replace the walls.
Compare various materials it is possible and necessary according to the characteristics. The characteristics, as noted above, are specified in the test reports:

• Compressive strength test report;
• Thermal conductivity test report;
• Frost resistance test report;
• Conclusion of Sanitary and Epidemiological Surveillance.

In some companies, instead of test reports, you may be shown videos of colorful tricks, the scripts of which are written by people who are unskilled from a technical point of view, but who are very successful in presenting the material to an inexperienced buyer. For a literate person, it is quite obvious that this cannot in any way replace real tests performed by a professional laboratory.
Any sane person will ask the question - If you are sure that your product is so good, why don’t you order testing from an independent laboratory, which, after testing, could confirm the figures you stated?

Summary.
When considering load-bearing wall materials: ceramic blocks, gas silicate, expanded clay concrete, arbolite, thermal blocks and their varieties, require the presentation of the above set of standard test reports. This is a minimum and mandatory set for any full-fledged production.

It is also necessary to understand. Any insulation in design - weak link and polystyrene foam is no exception. Obviously, insulation has a shorter service life than concrete or ceramic stone. Sooner or later the façade will have to be repaired. Check with the manufacturer offering multilayer structures whether regulations for façade repair work have been developed.

If you want to build a cost-effective home, o focus on modern technologies.

As an alternative, we recommend considering the most heat-efficient ceramic blocks produced in Russia Kerakam Cayman30.

Application of ceramic blocks Cayman30 allows you to build country houses, answering everyone current standards, and in particular, those that comply with SNiP " Thermal protection buildings" for cities such as Yekaterinburg, Novosibirsk, Perm, Krasnoyarsk, without inclusion in the design of an external wall weak link- layer insulation. Thermal calculations performed according to the SNiP “Thermal Protection of Buildings” methodology, confirming the statement, are presented below.

At the same time, the cost of constructing one square meter of housing will be one of the lowest when compared with any stone block, including in comparison with products called heat block, heat wall or thermoblock.

Below is a comparative calculation of the costs of an external wall using a thermally efficient ceramic block Cayman30 and an external wall in which a product called heat block, applied to specific project houses of our design.
If the thermally efficient ceramic block included in the project Cayman30 replace on product called heat block, final expenses for building a house will increase on 162,697 rubles.

Projects of houses made from ceramic blocks are included in the promotion Free house design .
According to the terms of the promotion when purchasing ceramic blocks Cayman30 in our company we will refund you the cost you paid project documentation

Below is a thermal engineering calculation performed according to the methodology described in SNiP “Thermal protection of buildings”.As well as an economic justification for the use of the ceramic block Kerakam Kaiman30 when comparing the costs of building the house in question using a product made of concrete or expanded clay concrete with insulation and a decorative panel.

First, let's determine the required thermal resistance for external walls residential buildings for the city of Dmitrov, as well as the thermal resistance created by the structures in question.

The ability of a structure to retain heat is determined by such a physical parameter as the thermal resistance of the structure ( R, m 2 *S/W).

Let us determine the degree-day of the heating period, °C ∙ day/year, using the formula (SNiP “Thermal protection of buildings”) for the city Dmitrov.

GSOP = (t in - t from)z from,

Where,
t V- design temperature internal air buildings, °C, taken when calculating the enclosing structures of groups of buildings indicated in Table 3 (SNiP “Thermal protection of buildings”): according to pos. 1 - according to minimum values optimal temperature corresponding buildings according to GOST 30494 (in the range 20 - 22 °C);
t from- average outside air temperature, °C cold period, for the city Dmitrov meaning -3,1 °C;
z from- duration, days/year, of the heating period, adopted according to the set of rules for a period with an average daily outside air temperature of no more than 8 °C, for the city Dmitrov meaning 216 days.

GSOP = (20- (-3.1))*216 = 4,989.60 °C*day.

The value of the required thermal resistance for the external walls of residential buildings will be determined by the formula (SNiP "Thermal protection of buildings)

R tr 0 =a*GSOP+b

Where,
R tr 0- required thermal resistance;
a and b- coefficients, the values ​​of which should be taken according to Table No. 3 of SNiP “Thermal Protection of Buildings” for the corresponding groups of buildings, for residential buildings the value A should be taken equal to 0.00035, the value b - 1,4

R tr 0 =0.00035*5 181.5+1.4 = 3.1463 m 2 *S/W

The value of the required thermal resistance for the external walls of residential buildings in a number of Russian cities

Formula for calculating the conditional thermal resistance of the structure under consideration:

R0 = Σ δ n /λ n + 0,158

Where,
Σ – symbol of layer summation for multilayer structures;
δ - layer thickness in meters;
λ - thermal conductivity coefficient of the layer material subject to operational humidity;
n- layer number (for multilayer structures);
0,158 - correction factor, which can be taken as a constant for simplicity.

Formula for calculating the reduced thermal resistance.

R r 0 = R 0 x r

Where,
r– coefficient of thermal technical homogeneity of structures with heterogeneous sections (joints, heat-conducting inclusions, vestibules, etc.)

According to standard STO 00044807-001-2006 according to Table No. 8, the value of the coefficient of thermal uniformity r for masonry made of large-format hollow porous ceramic stones and gas silicate blocks should be taken equal to 0,98 .

At the same time, I would like to draw your attention to the fact that this coefficient does not take into account the fact that

1. we recommend masonry using warm masonry mortar (this significantly levels out the heterogeneity at the joints);
2. As load-bearing wall and facing masonry connections, we use not metal, but basalt-plastic connections, which conduct heat literally 100 times less than steel connections(this significantly levels out the inhomogeneities formed due to heat-conducting inclusions);
3. window slopes and doorways, according to our design documentation, are additionally insulated with extruded polystyrene foam (which eliminates heterogeneity in the areas of window and door openings, vestibules).

From which we can conclude that when following the instructions of our working documentation, the coefficient of masonry uniformity tends to unity. But in calculating the reduced thermal resistance R r 0 we will still use the table value of 0.98.

R r 0 must be greater than or equal to R 0 required.

We determine the operating mode of the building in order to understand what the thermal conductivity coefficient is λ a or λ in taken when calculating the conditional thermal resistance.

The method for determining the operating mode is described in detail in SNiP "Thermal protection of buildings" . Based on the specified normative document, let's follow the step-by-step instructions. 1st step. Let's define son the humidity of the building region - the city of Dmitrov using Appendix B of SNiP "Thermal protection of buildings".

According to the table the city Dmitrov located in zone 2 (normal climate). We accept value 2 - normal climate. 2nd step. Using Table No. 1 of SNiP “Thermal protection of buildings” we determine the humidity conditions in the room. At the same time, I draw your attention to heating season air humidity in the room drops to 15-20%. IN heating season air humidity must be raised to at least 35-40%. A humidity level of 40-50% is considered comfortable for humans. In order to raise the humidity level, it is necessary to ventilate the room, you can use air humidifiers, and installing an aquarium will help.

According to Table 1, the humidity conditions in the room during the heating period at air temperatures from 12 to 24 degrees and relative humidity up to 50% - dry. 3rd step. Using Table No. 2 of SNiP “Thermal protection of buildings” we determine the operating conditions. To do this, we find the intersection of the line with the value of the humidity regime in the room, in our case it is dry, with humidity column for the city Dmitrov, as was found out earlier, this value normal.

Summary. According to the SNiP methodology "Thermal protection of buildings" in the calculation of conditional thermal resistance ( R0) value should be applied under operating conditions A, i.e. thermal conductivity coefficient must be used λa. You can see it here Thermal conductivity test report for ceramic blocksKerakam Kaiman 30. Thermal conductivity value λa You can find it at the end of the document.

Ceramic block Kerakam Kaiman 30 wall thickness 300mm. The façade is finished with decorative plaster. The total thickness of the wall excluding the plaster layer is 300mm (2mm decorative plaster + leveling lightweight cement plaster 15mm +300mm ceramic block Kerakam Kaiman30 + 20mm lightweight leveling plaster). 2 layer– 15mm thermal insulation plaster(thermal conductivity coefficient 0.18 W/m*C). 3 layer- 300mm wall masonry using block Kerakam Kaiman30(thermal conductivity coefficient of masonry in operational condition A 0.094 W/m*S). 4 layer– 20mm heat-insulating plaster (thermal conductivity coefficient 0.18 W/m*C).

Let's consider a product made of concrete or expanded clay concrete with insulation and decorative panel. The total thickness of the wall is 396 mm (58 mm decorative sand-cement or expanded clay concrete slab + 135 mm layer of thermal insulation in the form of polystyrene foam PSB25 + 203 mm layer of sand concrete or expanded clay concrete). 1 layer- 58 mm decorative sand-cement/expanded clay concrete slab. 2 layer- 135mm expanded polystyrene foam. 3 layer- 203mm sand concrete/expanded clay concrete. 4 layer- 20mm heat-insulating leveling plaster inside walls.

We consider the conditional thermal resistance R 0 external wall designs from Cayman30 blocks, based on data from a test report on the thermal conductivity of the masonry fragment of the wall.
Test report for thermal conductivity in masonry ceramic block Cayman30.

You can calculate the thermal resistance of products called heat block, thermoblock, heat wall, polyblock if the specific manufacturer whose products you are considering provides you with a test report for thermal conductivity in masonry.

R 0 Cayman30 =0.0020/0.84+0.015/0.18+0.300/0.094+0.02/0.18+0.158=3.5677 m 2 *S/W

We consider the reduced thermal resistance R r 0 .

The design of the external wall in which the block is used Cayman30

R r 0 Cayman30 =3.5677 m 2 *S/W * 0.98 = 3.4963 m 2 *S/W

The reduced thermal resistance of the external wall structure made from the Cayman30 block is higher than the required thermal resistance for the city of Dmitrov (3.1463 m 2 *S/W), which means that the design satisfies SNiP “Thermal protection of buildings” for the city of Dmitrov.

General information about ceramic block Kerakam Kaiman30 look in the section Real warm ceramics.

In an effort to make the work of builders easier, scientists have tried many different ways and technology. The idea to combine three qualities in a wall material turned out to be very productive in this regard: effective insulation, high bearing capacity and decorative finishing.

This is how thermal efficient units (TEB) were born. We will talk about what this masonry material is, what its objective advantages and disadvantages are in this article.

Blocks Thermowall. A short course in “anatomy”

The design of the heat block includes three layers:

• the external one is made of expanded clay concrete with textured surface simulating natural stone or brick;
• the middle one is formed by expanded polystyrene (foam plastic) with a thickness of 12 to 20 cm;
• the internal one consists of porous expanded clay concrete (M200).

Since foam plastic and expanded clay concrete are physically dissimilar, to prevent delamination of the wall, the outer and inner layers of the block are fastened with fiberglass or basalt rods.

Heat block (polyblock) design

Types of heat blocks

Manufacturers regulate the strength of the thermoblock using various brands cement mortar and expanded clay gravel (from M50 to M100).

The insulation in the block may be different. More cheap material made using ordinary polystyrene foam with a density of 25 kg/m3. Best performance energy savings are achieved by installing more expensive extruded foam.

The inner (bearing) layer of a polyblock can be solid or with voids. The latter option is used in the construction of houses with a height of more than three floors. Reinforcement is placed inside the voids and filled with mortar.

Since the thermal block is a single three-layer structure, it cannot be cut into pieces when laying. Taking this requirement into account, manufacturers produce a wide range of fuel cells. It includes not only row blocks different thicknesses, but also internal and external, waist and ventilation, half and opening.

Features of construction from heat blocks

The technology of masonry from three-layer blocks has much in common with the process of constructing walls from gas silicate blocks. The fundamental difference, as we have already said, is a ban on cutting blocks to preserve their integrity and unity of textured pattern.

The masonry is carried out using construction adhesive, maintaining the thickness of the seams in the range from 2 to 4 mm. Dense laying reduces heat loss through mortar joints, improving the thermal insulation qualities of the wall. The glue is applied with a notched trowel to the inner and outer layers of the block. The solution is not spread on the foam. The construction of the walls is carried out with ligation of seams in ½ block.

Vertical seams when laying heat blocks are sealed in a special way. They are sealed in the insulation area construction foam. The outer and inner seams in the expanded clay area are sealed with mortar using a construction gun.

The seam in the insulation area is filled with polyurethane foam

An important nuance is the reinforcement of the masonry after 3-4 rows steel mesh(cell 5x2 cm, wire thickness 0.5 mm).

Manufacturers claim that a block with insulation and cladding does not require a device reinforced belt(for the construction of houses up to two floors high). However, practice has shown that it should always be done before installing floor slabs. In order to reinforced concrete did not stand out on the façade; it was covered with thin belt blocks.

Installation of the armored belt frame. From the outside it is covered by a number of waist blocks

The support of the floor slabs on the wall made of thermoblocks must be at least 12 cm.

Owner reviews, pros and cons of heat blocks

There are few reviews from real owners of houses made from heat blocks. More often you can find information from manufacturers and dealers of this material. In it positive sides FEBs are extolled, and shortcomings are hushed up.

In the reviews that we found, home owners most often note the following advantages of thermal blocks:

• Affordable price;
• No costs for insulation and external finishing;
• Saving on heating;
• Given that high-quality ventilation A comfortable microclimate is established in the premises.

The disadvantages of fuel and energy sources include:

• Low durability of insulation (manufacturers unreasonably overestimate the service life to 100 years);
• The controversial environmental friendliness of polystyrene foam (in advertising there are statements to the contrary);
• Wetting of masonry joints during slanting rain (waterproofing treatment of the facade is required);
• It's hard to find a manufacturer that produces quality material and builders who are able to competently build houses from thermal blocks.

Dimensions, approximate prices and manufacturers

Ordinary polyblocks are produced in three basic standards (length, thickness, height): 40x40x19 cm, 40x30x19 cm and 20x40x19 cm. The last size is used for laying walls attic floors, as well as for construction in warm climates.

The sizes and prices of heating blocks are directly related to each other. Estimated cost(for 2016) colored ordinary block 40 cm thick - 260 rubles. In terms of 1 cubic meter, this will be 8,060 rubles.

Thinner colored 30-centimeter blocks are sold for 210 rubles apiece. Per cube their price will be 8800 rubles.

Ordinary colored blocks with air exchange are sold at prices ranging from 340 to 410 rubles/piece. Unpainted material can be purchased 10-12% cheaper.

You will not find a single all-Russian manufacturer of heating wall blocks that deserves complete trust. Therefore, in each region, before purchasing this material, you need to “take your eyes with you” and personally evaluate the quality. It is better to do this not in the dealer’s office, but in the workshop. Some manufacturers select ideal blocks for exhibitions, but substandard material can be found on pallets before shipment.

What do you think about this wall material? Perhaps you or your loved ones have experience building with these blocks, we will be glad to receive your feedback and comments.

Heat block - three-layer construction, each of which has its own purpose:

• load-bearing layer- the largest part of the block, made of expanded clay concrete;
• inner part- made of expanded polystyrene, providing thermal and sound insulation;
• monolithic concrete, 150 mm thick - having different types drawing and painted in any color.

All layers of the structure connected by reinforcing or basalt-plastic rods to enhance strength.

For the manufacture of heat blocks, local resources are used - ash, slag, which reduces the cost of construction

Thermal blocks are used for the construction of not only low-rise, but also multi-storey buildings.

Price of heat blocks

How much does a heat block cost? The price of heat blocks fluctuates from 3,000 to 7,000 rubles per cubic meter, it all depends on the selling price of the manufacturer. The size of the heating block is 400 * 300 * 200, the price of 1 heating block is from 150 to 200 rubles. There are 41 heating blocks in one m3.

Construction savings

Minimum labor costs- several times less due to laying in one row.

For example, house area 100 m2. In brick - when laying 2.5 bricks, the wall thickness is 640 mm, construction volume equals 0.64 * 100= 0.64 m3. If a mason produces 1.5 m3 per shift, he will need 48 days. Heat blocks - wall thickness 300 mm, volume equal to 0.3 * 100 = 30 m3. A mason will need 15 days to produce 1.9 m3 per shift.

• the cost of laying a house from heating blocks with an area of ​​100 m2 will be about 50,000 rubles. The cost of 1 m2 of a wall made of thermal concrete will be cheaper than the cost of 1 m2 of aerated concrete masonry by 15-20%, and 1 m2 of brick - by 25-30%;
• lack of finishing of the house outside - the manufacturer took care of decorative finishing, which eliminates unnecessary labor costs and materials consumption for construction. This saves another 1,500 rubles per 1 m2;
• special lifting equipment is not used - the heat blocks are light in weight. No need to pay for the faucet and wages crane operator;
• use of masonry adhesive - does not require large quantity water, sand and cement at the construction site;
• increase in house area due to thickness load-bearing structure- block thickness is 300 mm, which increases the area of ​​the house by 11-12 m2 (in brick - thickness 640 mm).

Fare

The thickness of the wall made of heat blocks is less 2 times than brick, and the weight is almost 3 times, which means the volume of transportation is less, because transportation depends on the weight and volume of the structure. This reduces transport costs by 2-3 times.

Short term construction

The walls are laid out in one block - the speed of wall laying increases, the quality does not suffer, construction time is reduced

Prices for building houses from heat blocks

Companies involved in the construction of houses from thermal blocks (polyblocks) offer prices for 1 m2 from 14,000 to 24,000 rubles, assuming that each house project is individual. The price depends on the area of ​​the house being designed - the larger the area, the lower the price. When concluding a contract, some companies promise to return part of the funds spent on the design. The area is taken to be the internal area of ​​the house and the area of ​​balconies, terraces, etc.

The cost of house area per 1 m2 depends on:

• length and width of the house;
• how many floors are there in the house?
• from the project
• construction sites

Price of house area per 1 m2 from 15,000 rubles

This includes All Construction Materials and work:

• foundation - strip monolithic with shallow depth;
• walls made of heat blocks - load-bearing and without it;
• ceilings, beams;
• finished roof;

• delivery of materials

The price of 1 m2 of area of ​​a house made of heat blocks is from 18,000 rubles

In addition to the previous configuration:

• plastic windows;
• entrance door;
• electricity, sewerage, heating;
• wall upholstery with plasterboard, plaster;
• suspended ceilings

The price for 1 m2 is over 18,000 rubles depending on additional solutions customer.

What is beneficial about houses made from heat blocks is that without having the means to use construction company, you can build a house yourself. To do this, you do not need to be a highly qualified specialist - it is enough to have some construction experience.

By building such a house, you save on transportation costs, eliminate unnecessary labor costs and material consumption, and do without special lifting equipment.

In addition to homogeneous masonry materials such as brick or various blocks based on cement, in last years Composite ones are also gaining popularity among private owners. The craftsmen of the FORUMHOUSE portal tried out a relatively new one - a heat block.

• Energy efficiency of heating blocks

Heat block - characteristics, features, scope of application

The thermally efficient block, abbreviated heatblock, consists of three layers:

• Structural (load-bearing) - porous block of expanded clay concrete, density 1300-1500 kg/mᶟ.
• Thermal insulation - expanded polystyrene (EPS) or extruded polystyrene foam (EPS), 150-200 mm thick.
• Facing (decorative) - a thin block of expanded clay concrete or concrete (on average 50 mm), characterized by increased density, strength and frost resistance; the surface imitates figured or smooth brick, natural stone.

Heat blocks are produced using two methods – vibration casting or vibration pressing:

• Vibration casting - an insulation insert is installed in the matrix, the liquid solution is poured into the mold and processed on a vibrating table until the block is completely compacted.
• Vibropressing – a solution in the form of a vibropress with installed liner it is filled in semi-dry, the block is simultaneously exposed to vibration and pressure.

After molding, blocks produced by vibrocompression are placed in a heat chamber for finishing, and the vibrocasts dry naturally.

It is believed that stronger and more durable blocks come out of the press.

The layers are connected to each other not only due to adhesion - manufacturers use special bonds, this can be metal-plastic, fiberglass or basalt rods. Heat blocks are also produced with additional voids in the structural layer; during the laying process, reinforcement is installed in them and mortar is poured.

The facing layer can be the same as the original one, gray, and multi-colored, you can order almost any shade at the factory.

The main advantages of the blocks include minimal thermal conductivity, due to which a wall 30-40 cm thick does not need additional insulation, and the presence of a finishing layer. The facade is immediately decorative and does not require cladding, plaster or various hanging screens. In addition, the load-bearing part of the block made of lightweight concrete significantly reduces the weight of the structure, making it possible to dispense with strip foundation. As for the speed of construction, which is also an advantage of the material, it is also inherent in other block categories and largely depends on the skill of the performers. The same can be said about minimum consumption mortar - a thin seam is typical for wood concrete, gas silicate or warm ceramics, but whether it can be done this way depends on the craftsman and the geometry of the blocks.

There are also some shortcomings, the main one of which is the harmfulness of polystyrene foam, the battles on the topic of which do not subside. Perhaps PPS is not the most environmentally friendly of insulation, but still it is covered with a load-bearing layer and interior decoration, and the thermos effect inherent in such houses is neutralized by a good ventilation system. Users have much more complaints about unscrupulous manufacturers, whose products boast “walking” geometry, reduced strength and other “amenities” associated with violation of technology.

To avoid purchasing such a heat block, you need to be more careful in your choice and trust only with my own eyes, hands and product certificates.

The main area of ​​application for heat blocks is low-rise private construction, which includes not only houses, but also various outbuildings. Blocks intended for additional reinforcement can be used for laying higher buildings, but, of course, we are not talking about “candles”.

How I built a house from thermal blocks

A detailed description of the construction of a house from a heat block and his feelings from its operation by one of the craftsmen of our portal with the nickname Storyteller14 posted in the topic of the same name.

Storyteller14 FORUMHOUSE Member

At first I didn’t know what to build a house from, but by chance I saw a house made of thermal blocks and I liked the material. I went to that construction site, asked around, and decided to build a house from a heating block. Firstly, the house should be very warm, and secondly, savings on finishing works on the outside, the heating block is already beautifully lined; thirdly, there is savings on façade insulation and painting work.

At the production site, calculations were made based on the project, the craftsman ordered wall, corner blocks and quarters, chose colors, for the plinth - concrete tiles with a texture like blocks, fastened with dowels. The promised deadline was a month, but in reality they didn’t even meet it in two; instead of October, the blocks were ready only in May. On the plus side - no problems with storage, one hundred thousand penalties and free shipping. The downside is that different batches differed in the shade of the cladding, the gamma is the same, but the saturation is different, we had to solve this problem during the laying process. To save additional money, we purchased all the lumber (150x150 boards and inch boards) in winter.

Foundation – insulated tape 1 meter deep with compacted sand bedding and crushed stone cushion, PSB slabs. In the outgoing construction season, the base was laid out from expanded clay concrete and left to winter.

Box – the walls began to be erected in May, since the foundation was not initially tied to wall material, seam thickness according to different walls ranged from 5 to 10 mm. This led to difficulties with the masonry mixture - the purchased adhesive for foam concrete was not designed for such fluctuations, so they began to mix it with cement, and the seams were also foamed polyurethane foam. The addition of cement showed itself as efflorescence on the masonry.

Roof – the grooves for the joists in the blocks were sawn through with a grinder, all the seams were carefully foamed, the floor beams were glued together by a craftsman from boards. The project provides for a low roof, and although, according to the discussion participants, one-story house with an area of ​​130 m² it looks organic, Storyteller14 believes that the skate should have been raised. As roofing The craftsman chose metal tiles with a sheet thickness of 0.5 mm.

Energy efficiency parameters – not only are the walls made of heat-efficient material, but the heat loss of the house depends on the insulation parameters of the floors, and on the tightness of windows and doors. The house has a large proportion of glazing, in order to reduce heat loss through the windows, energy-saving double-glazed windows were chosen.

Storyteller14

There are a lot of windows in the house, but since I wanted to retain the heat as much as possible, they were given Special attention. We installed windows 74 mm thick, with two energy-saving glasses, a warm frame and argon filling, plus medium armor glass - A3.

Initially, the floor and attic were insulated with a thickness of 200 mm; this turned out to be enough for the floor, but not enough for the attic, as a thermal imaging test showed. Attic floor added another layer of insulation mineral wool 200 mm thick.

To further improve your home's energy efficiency, Storyteller14 organized through a ground heat exchanger. I buried a HDPE pipe with a cross-section of 160 mm on the site at a depth of two meters, the length of the main line is 50 meters. According to calculations, 60 were needed, but the area is compact, the pipe comes out in the base. As winter tests showed, everything worked out.
