Wall with solar heating air ducts - has corrugated sheet between outer cladding and insulating layer on substructure

摘要

The wall or roof has external insulation and ducts for heat exchanging air movements over the insulation. The construction includes rigid structural beams (6), a rigid insulation layer (4), the ducts (3, 8) and an external waterproof cladding (2). The ducts traverse a plane exposed face of the insulation. The ducts are formed by locating corrugated sheeting between the insulation (4) and the cladding (2). The undulations are rectangular, trapezoidal or sinusoidal. Alternatively a longitudinally honeycombed slab forms the ducts, or the cladding is mounted on a plain board supported by stools or battens. The corrugated sheet is of cardboard, asbestos, metal, or plastics.
