DEVICE FOR ADDITIONAL HEAT INSULATION OF EXTERNAL WALLS OF PREMISES IN OPERATED BUILDINGS Russian patent published in 2015 - IPC E04B1/76 

FIELD: construction.

SUBSTANCE: device for additional heat insulation of external walls of premises in operated buildings includes an air layer filled with a frame and formed by an external wall and facing coated from outside with a reflecting material in the form of aluminium foil. The frame is made from sheet corrugated aluminium foil laid in waves horizontally to all volume of the layer and attached to the facing by wave ridges. The facing is made of composite material, including hard material, for instance, an aluminium plate, heat insulation fibre from basalt material and aluminium foil. The hard material at the side of the room is coated with heat insulation fibre attached to aluminium foil. Composition of the aluminium foil with high coefficient of heat conductivity and fibre from basalt material with low coefficient of heat conductivity they create bimaterial along with the flow of heat flow. Heat insulation fibres from basalt material are arranged on aluminium foil in the form of a row of bundles extended bottom up. Each row of a bundle of basalt fibre is zigzag-shaped and is in pairs made up by serially alternating diffusers and confusors.

EFFECT: invention makes it possible to reduce thermal losses from premises via external walls.
