FIELD: construction.
SUBSTANCE: invention relates to layered heat-waterproofing coatings used for thermal and waterproofing protection of building structures, brick, concrete and reinforced concrete surfaces of external and internal enclosing and load-bearing structures, including foundations, plinths, walls, partitions, floors, as well as ventilated and non-ventilated combined and attic roofs, roofs at operating temperatures from -60°C to +260° C. Non-flammable vapour-permeable heat-waterproofing of building envelopes and structures based on a combination of ultra-thin thermal insulation based on vacuumized microspheres and a waterproofing coating contains layers successively applied to the protected surfaces of structures: an adhesive layer in the form of an organosilicon primer based on an aqueous solution of potassium methyl siliconate; a layer of insulating plaster, with a density of at least 700 kg/m3, based on foamed polystyrene with the addition of a binder; reinforcing layer; the main thermal insulation layer in the form of non-flammable (NG class) vapour-permeable ultra-thin thermal insulation with a vapour permeability coefficient of 0.03 mg/(m⋅h⋅Pa) and thermal conductivity coefficient 0.001 W/(m⋅°C) based on hollow microspheres, with a total thickness of the thermal insulation coating from 0.5 to 4.0 mm; putty layer in the form of a sound-heat-insulating material additionally containing air gel; finishing waterproofing layer in the form of a polymer non-flammable waterproofing coating based on synthetic rubber polymer with the addition of a fire retardant.
EFFECT: expanding the scope of application of ultra-thin heat insulators based on hollow microspheres by installing a non-flammable waterproofing, water-repellent heat-insulating coating based on hollow microspheres, while maintaining all the thermophysical properties of the heat-insulating coating, and, as a result, increasing the overall heat transfer resistance of the resulting protective coating, for thermal waterproofing of external and internal enclosing and load-bearing structures, including foundations and plinths.
