"Brick of a new generation" - this is often called the heat unit, which was widely used in almost all areas of modern construction. Let's figure out what a heat box is, and what advantages it allowed him to achieve record high demand in the building materials market.

Video What is a heat block?
A heat-efficient wall unit or simply a heat unit is a three-layer construction with a relatively small weight. The composition of the heat-block includes 3 parts, each of which performs a certain functional load.
As a material for the production of the main( bearing) part of the material, porous claydite concrete is used. The inner cavity of the mold made of it is filled with expanded polystyrene, which acts as a highly effective insulator. The outer surface of the resulting structure is covered with textured expanded clay concrete. At the same time, the surface of the finished block can have many variants of decorative relief, the most popular among which are "brick" and "stone".
Thus, the heat unit is an improvised sandwich, the layers of which are securely fastened together by two reinforced fiberglass or basalt plastic rods.
The main advantages of
Due to the technical characteristics peculiar to each individual heat-block, this material is a universal building unit of the new generation. And to judge about it allow the inherent properties of thermal insulation blocks, among which:
- heat efficiency;
- budget( saving on delivery and working mixtures for styling);
- possibility of use in "fast construction";
- is easy to use( the blocks are geometrically accurate, light and textured, which greatly facilitates the process of their laying);
- durability;
- fire safety( internal "combustible" liner made of expanded polystyrene is treated with flame retardant at the production stage);
- aesthetic appeal and a variety of options for exterior finishing of the material;
- environmental safety.
All of the above listed advantages make it possible to safely call thermal insulation blocks the material of the future, capable of opening new horizons in the construction issues.
Scope of application
Heat-generating units are in great demand when erecting load-bearing wall constructions of various types of buildings and structures. Less often( due to its size), the material is used to create internal partitions.
The main area of application of heating units is low-rise construction of residential buildings, as well as objects of economic purpose. Nevertheless, in case of additional reinforcement of the supporting part of the material, it is possible to use it when building higher construction objects.
Today, thermal insulation blocks are widely used in the so-called "rapid construction" due to the possibility of their maximum operational, budgetary and non-labor stowage in wall structures, which, in addition, do not require further finishing before commissioning of the structure.
Technical characteristics of the
heat-insulating unit The heat-generating units meeting the requirements of the relevant regulations have the following technical characteristics:
- density of outer layer of expanded clay concrete - 1800 kg per cubic meter;
- density of the bearing( inner) layer of expanded clay concrete - no higher than 1690 kg per cubic meter;
- class of expanded clay in both layers - not lower than M200( B15);
- frost resistance of the decorative layer - F100( 100 or more cycles);
- frost resistance of bearing claydite concrete - not less than F50( 50 or more cycles);
- coefficient of resistance to heat transfer - 4.78 m2 * C / W;
- thickness of the inner layer of claydite-concrete 150-200 mm;
- thickness of thermal insulation layer - from 160 to 200 mm;
- thickness of the outer layer - more than 50 mm;
- the weight of one block does not exceed 31 kg;
- overall dimensions of a private block heat-generator - 400 * 200 * 400 mm;
Species
Modern manufacturers offer a variety of types of thermal insulation blocks, the differentiation of which is based on:
- degree of strength of the carrier layer( mainly claydite grade M50, 75 and 100);
- used as a heater as expanded polystyrene( normal or extruded);
- structural integrity of the supporting part( integral or provided with voids for additional reinforcement reinforcement of claydite concrete layer);
- the size and decorativeness of the blocks.
More details on the types of thermal insulation blocks will be provided by the photos and videos attached to the article.
Drawbacks of
thermal insulation blocks Despite the presence of a number of advantages over other construction materials of the same class, the heaters also have some drawbacks. Thus, samples of material made of cast fibrous concrete poorly pass air, which prevents the "breathing" of the inner premises of the structures constructed with their help. This fact is evidenced by numerous reviews of owners of residential houses from low-quality or poorly suitable for individual construction of samples of thermal insulation blocks.
In addition, the relatively large( in comparison with a brick, for example) the size of the blocks does not always have to be "on hand" when constructing complex architectural points of view or when building houses in extremely small areas.
As a whole, heat-blocks are inexpensive and easy to use construction materials, allowing in a record short time to build reliable, durable and aesthetically attractive objects for residential and household purposes.
