DEVICE FOR ADDITIONAL HEAT INSULATION OF EXTERNAL WALLS OF OPERATED BUILDING PREMISES Russian patent published in 2013 - IPC E04B1/76 

FIELD: construction.

SUBSTANCE: device comprises an air layer filled with a frame and formed by an external wall and lining coated from the external side with a reflecting material in the form of an aluminium foil. The frame is made of sheet wavy aluminium foil arranged in waves horizontally in the entire volume of the layer and attached to the lining by wave ridges. The lining is made of a composite material, including a solid material, for instance, an aluminium plate, a heat insulation fibre of a basalt material and an aluminium foil. The solid material at the premise side is coated with the heat insulation fibre attached to the aluminium foil. The composition of the aluminium foil with high coefficient of heat conductivity and fibre of the basalt material with low coefficient of heat conductivity create a bimaterial along with the thermal flow motion.

EFFECT: invention makes it possible to reduce heat losses from a room via external walls.
