The use of light frame structures allows for the same site area to get more living space, which affects the economic feasibility of the system; moisture condensed inside the system exterior insulation, evaporates quickly, without causing waterlogging design; Possibility store heat in the building envelope (0 C isotherm is located inside the insulating material); no thermal strains in load-bearing wall. All outdoor temperature swings seen insulation obstacle to the destruction of concrete and corrosion of steel reinforcement in the performance of load-bearing walls made of concrete. For concrete virtually no access to CO2, water and other corrosive substances and gases lack of "efflorescence" on facades; in panel construction solves the problem of protecting interpanel seams greatly increases the sound insulation of external walls; possibility to use both new construction and renovations on buildings. Like every technology or design, the system of "wet" facade has some limitations. First of all – the seasonality of works, because This technology requires a wet processes, which can be only in warm weather (up to +5 C). Facade insulation systems of "wet" type design are classified into two types: – Systems with rigid fixation of a heater on the wall ("sealed" type) – a system with flexible (mobile) fasteners insulation. As a heater in the "wet fronts" are used penopolitisrolnye plate mark 25, corresponding terbovaniyam fire safety set out in the NPB 244-97: have a group of combustibility – T1 according to GOST 30244-94 (flammable material on SNIP 21-01-97), a group of flammability in accordance with GOST 30402-96 B2 (flammable material is moderately to snip 2101-97). Calculation parozaschity walls shall be in accordance with the requirements of SNIP II-3-79 *. Values average ambient air temperatures, by SNiP 23-01-99 "Building climatology." The use of polystyrene foam on the facade of the building as recommended in the case when the cladding (the carrier or self-supporting) piece made of porous materials based on lightweight concrete.
