DWS consists of 2 layers of LGSF that do not touch each other, so the formation of “cold bridges” is excluded. Polystyrene concrete, in turn, is an excellent insulator due to its density of 150-350 kg/m3. According to calculations, 380 mm thick walls with polystyrene concrete have thermal insulation properties equivalent to 1.5-meter brickwork.

One of the main properties of capital buildings is their strength. The strongest type of construction is monolithic frame construction, where reinforced concrete columns and floors (reinforcement and concrete) serve as the frame, and the wall infill can be aerated concrete, brick, ceramic block, etc.

In our case, the walls and floors consist of a solid reinforced concrete frame, but made of lightweight, durable steel structures and lightweight polystyrene concrete, which work together as a single structure.

The light weight of the structure allows the house to be placed on any support base. Installation without a foundation is also possible, depending on the soil geology.

The frame is not afraid of moisture. It is made of steel in accordance with DSTU R 52146-2004 with an anti-corrosion zinc coating with a density of 275 g/sq.m. Polystyrene concrete is a moisture-resistant material that does not sink in water and does not lose strength and thermal insulation properties from moisture. Mold does not develop on its surface.

Polystyrene concrete consists of Portland cement and expanded polystyrene granules. It is the only type of lightweight concrete that has plasticity. Standard sound insulation is 53-63 dB. If necessary, the characteristics are increased.

Due to the fact that polystyrene concrete has small air pores in its composition, short waves are damped, and due to the presence of large pores filled with foamed polystyrene balls, long sound waves are damped. As a result, polystyrene concrete acquires high soundproofing properties that are superior to those of competitors.

The frame is made of steel, a non-combustible material. The wall filler polystyrene concrete belongs to the flammability group G1. It does not catch fire and does not support combustion.

The walls and floors are a combination of galvanized steel, concrete, and cladding plates. The result is an earthquake-resistant monolithic structure.

* LGSF construction is very common in earthquake-prone areas. This technology became especially popular after the 1995 Kobe earthquake (Japan). It was found that LSTS buildings were more resistant to seismic shocks than others. Double-frame LSTS walls can withstand a 9-point earthquake, flooding and wind speeds of up to 260 km/h. At the same time, the entire load is borne by metal structures.

The frame, technological slots, cutting, and marking of parts are made using CNC (Computer Numerical Control). Thanks to the combination of the latest generation CNC and licensed software, the speed of frame production is 100 square meters / 2 days. The frame parts are fitted with an accuracy of 0.5 mm. For assembly, two tools are enough to choose from - a screwdriver or a hand riveter. Accurate calculation of materials makes it impossible to leave materials behind after construction.
