Rigid insulating panel for construction, industry and other uses has sheets with triangular corrugations inside sealed hollow casing

摘要

The insulating panel consists of a sealed hollow casing with walls (1 - 6) of plastic, wood, plaster, metal or composition material, containing sheets with triangular or curved corrugations lying perpendicular to one another in adjacent sheets. The gaps between the corrugations can be filled with acoustic or thermal insulation materials such as glass wool, rock wool, hemp, plaster or recycled materials.
