FIELD: construction.
SUBSTANCE: present invention relates to facade heat-insulating composite systems. Invention discloses a stone wool slab for a heat-insulating layer of a facade heat-insulating composite system, which consists of a main element with thickness of 50–250 mm and density of not less than 120 kg/m3 and an additional element with thickness of 20–100 mm and density of not less than 130 kg/m3, glued to each other using a foam glue, note here that the thickness of the additional element makes not more than 1/2 of the thickness of the main element, while the adhesive foam is applied in the form of a cellular grid with a cell side of not more than 300 mm and a strip width of 50–80 mm, preferably about 70 mm. Also described is a method of mounting a facade heat-insulating composite system on a wall having deviations from the vertical and/or horizontal along the plane of the facade of more than 20 mm.
EFFECT: invention makes it possible to increase the thickness of the heat-insulating layer, while maintaining its vapor permeability, and, as a result, to improve the thermal characteristics of the facade heat-insulating composite system, and also to reduce consumption of adhesive mixture for gluing plates to wall.
