Residential houses of mass development constitute peculiar problem – bearing-wall houses, pre-engineered buildings, brick houses, constructed by standard projects of first generation.
The necessity of reduction of expenditures on wall materials, reduction of weight of multi-storied buildings and increased requirements on advanced energy-saving properties of external walls resulted in creature of facade thermal insulation systems in the form of multilayer structures, using highly-efficient thermal insulation materials.
