The sphere of production of building materials over the past few years has stepped far forward, which allowed to ensure the construction of high-quality products. Ceramic and silicate bricks over time gave way to various foam and gas blocks. Such materials greatly simplify and reduce the cost of the construction process, making it possible to erect objects of better quality and speeding up the process of building construction.
Among all modern building materials, twin blocks from Yekaterinburg produced by the Teplit plant stand out for their quality and compliance with the declared characteristics and sizes. Twin blocks are made of cellular concrete, a chemically inert substance consisting of Portland cement, silicate sand and aluminum powder, which acts as a foaming agent. A large number of pores reduces the thermal conductivity and weight of the twin block in comparison with other building materials.
What is a twin block?
In the production of this building material, modern equipment is used that determines not only high quality, but also the ideal geometric dimensions of the Birch twin blocks. The Teplit trademark is a guarantee that blocks from different parties will have identical sizes, which allows to save on the finish of finished premises and simplify the construction process. The characteristics and sizes of twin blocks for construction allow finishing to be completed without the use of a large number of finishing materials.
The differences of the tween block:
- Ease of installation and affordable cost, which determines the wide range of use of twin blocks in private construction. The construction of objects from twin blocks using special glue is several times cheaper than similar structures made of ceramic brick in mortar.
- There is no need for the delivery of large batches of cement mortar, since the storage and use of dry mixes is more profitable from an economic point of view.
- Like twin blocks, the glue used for their construction has low thermal conductivity, which eliminates the problem of cold bridges.
- Twin blocks are available in several sizes for different walls and partitions. Each unit is equipped with a groove-comb system, so that they can be folded according to the Lego cubes principle. The grooves in the wall blocks simplify and speed up their installation.
Specifications
Manufactured products are marked by the manufacturer in terms of density and size and are suitable for all wall structures:
- The dimensions of the twin unit are 300 TB-300: 625 x 300 x 250 millimeters.
- Dimensions TB-200: 625 x 200 x 250 millimeters.
- The dimensions of the twin block 400 TB-400: 625 x 400 x 250 millimeters.
- Dimensions TB-100: 625 x 100 x 250 millimeters.
The physicomechanical properties of the material depend on its density, due to which it is possible to choose twin blocks for a specific case.
The density of the twin blocks are divided into three types:
- D400 - density 400 kg / m 3 .
- D500 with a density of 500 kg / m 3 .
- D600 with a density of 600 kg / m 3 .
The fire resistance for all types of blocks is REI 240, the specific effective activity is EPH 94.2 Bq / kg.
The composition of the twin blocks
For the manufacture of twin blocks, standard building materials are used:
- aluminum powder;
- cement;
- lime;
- water.
Due to its light weight, ease of manufacture and large size, the twin blocks are considered the ideal building material. When laying them, you can not use a classic mortar - just use high-quality glue, which allows you to perform the whole complex of construction works.
The advantage of the adhesive is to increase the thermal resistance of the entire masonry, which simplifies the drying process and improves the properties that allow the material to retain heat.
Application area
The main scope of use of twinblocks is the construction of public and residential buildings and low-rise construction. Due to the technical characteristics and dimensions, twin blocks can be used in the construction of internal and external walls and partitions, where the soundproofing qualities of the material play a special role.
Advantages and disadvantages of twin blocks
Like any other building material, a twin block has its own strengths and weaknesses.
Its advantages include low thermal conductivity, geometric accuracy, environmental friendliness and incombustibility.
The downside is the increased level of water absorption, because of which the walls of the twin blocks are additionally protected from moisture by means of facade finishing materials.
Additional benefits
- The low weight of the twin blocks simplifies the work with them. All the grooves, regardless of the size of the twin blocks, are made with geometric accuracy, which allows you to make perfectly even masonry.
- Despite the fact that the twin blocks include lime and cement, they are highly environmentally friendly. Products manufactured under the Teplit brand have the appropriate quality certificates.
- Twin blocks easily undergo deformation - they are reinforced, sawn and drilled, thanks to which it is possible to create walls of any geometric shape from them.
- The thorn-groove connection prevents the appearance of cold bridges and allows you to reduce the distance between adjacent blocks.
- High thermal insulation properties. Twinblocks have low thermal conductivity, which is further reduced due to locking joints. Due to these characteristics, in the cold season, heat does not escape through the walls, and during the warm period the inside of the house is kept cool.
- Ecological purity and material safety. Building blocks are made of natural components. In the event of a fire, the twin blocks do not emit harmful substances into the air. In terms of safety, this material is not inferior to glass, wood, brick or natural stone.
- Simplicity of work. Unlike other building materials, the geometric dimensions of the twin blocks are ideal, in addition, the blocks are equipped with tongue-and-groove joints, which simplifies the laying due to the similarity of the process with the assembly of the designer. The light weight of the blocks and their large volumes accelerate the construction of construction projects.
- Fire resistance characteristic of other concrete products.
- Affordable cost of twin blocks.
- Domestic production of material.
Reviews
The houses erected from the twin blocks collect positive feedback from the owners, since the building material provides heat in the cold season and cool in the summer, thereby saving on air conditioning and heating.
In the reviews of the twin blocks, which are often called greenhouses, they are noted for their low weight, ease and speed of installation, the possibility of using glue, and not mortar. In the cold season, minimal heat loss through the walls is recorded. Regardless of size, the twin blocks are geometrically accurate, which makes it possible to erect perfectly even walls.
Twinblock Tips
- Twinblock construction projects are being built at temperatures between 5 and 25 degrees Celsius. At a higher temperature, the material is necessarily moistened, at low temperatures a special glue is used.
- It is advisable to lay the first row of twin blocks on cement mortar, and not on glue, so that it turns out to be perfectly even. Raising or lowering the block relative to the neighboring ones is carried out by using a larger amount of the mixture or by pressing the twin block into the solution.
