FIELD: heat insulation materials.
SUBSTANCE: invention can be used in construction of various objects, civil and industrial, in which it is necessary to provide heat insulation. Combined heat-insulating panel is made of foam material and mineral wool, note here that it has non-uniform structure and is made by pressing mineral wool bars into foam material uniformly over the area. Note here that mineral wool bars and foam material have the same thickness. Amount of mineral wool is in range of 20 to 80% of the total volume of the insulation sheet. Foam polystyrene, extruded foamed polystyrene, foamed plastic, foamed concrete and foamed glass can be used as the foam material.
EFFECT: heat-insulating panel has uniform fire resistance, vapor permeability and compression strength; claimed invention makes it possible to easily control the specified characteristics by changing content of mineral wool in foam material.
