FOAM POLYSTYRENE FOR THE FACADE
Wet stucco facades
The solution of walls with a finishing layer of thin-layer stucco was developed on the basis of facade systems with a thin outer plaster layer for thermal insulation from cut polystyrene foam panels of facade grades with graphite content PPS15F-RG, PPS20F-RG and without graphite content PS16F-R for low-rise residential buildings of constructive fire class hazards C3 up to 3 floors inclusive. The basis for the facade system with a protective and decorative layer of thin-layer plaster with a thickness of 6 - 8 mm are: external load-bearing or self-supporting walls made of monolithic reinforced concrete or piece materials (brick, stones, cellular concrete and concrete blocks).
When performing multilayer walls with a protective and decorative layer of brick, heat-insulation is made using polished polystyrene plates made of expanded polystyrene grades PPS10, PPS12, PPS13 or PPS14. Multilayer walls with brick cladding can be made load-bearing and non-bearing for buildings up to 75 m high.Laminated exterior walls with an effective heat-insulating layer and a protective brick wall are used for buildings with dry and normal temperature and humidity conditions (SP 15.13330). The use of a three-layer masonry with effective insulation for the external walls of rooms with a wet operating mode is allowed provided that a vapor barrier coating is applied to their internal surfaces.
