FIELD: heating.
SUBSTANCE: invention relates to composite systems of heat insulation of an outer wall of the building. The composite system of heat insulation is attached to the surface of the outer wall of the building, facing in the direction opposite to the building. The composite system of heat insulation comprises at least two-layered heat insulating coating with at least two layers, each of which comprises from 25 to 95 wt % of aerogel, from 5 to 75 wt % of inorganic fibres, and from 0 to 70 wt % of inorganic fillers. The layers of the heat insulating coating are connected to each other by an inorganic binding material. The composite system of heat insulation has a total heat capacity which is less than 3 MJ per kilogram.
EFFECT: invention enables to improve the mechanical stability of the heat insulation system and to improve its thermo-technical characteristics.
