Cladding over heating of building - has outermost covering over transparent insulation, an air gap layer whose transparency depends on temp. and absorber background

摘要

A cladding for the heating of a building consists of a transparent seal, transparent insulation and a layer whose transparency is temp.-related ('thermotropic') and which is positioned in front of the part of the building to be heated. This last layer is parallel to the cladding and inside the transparent insulation, it pref. consists of a mixt. of solns. of polymer(s) (e.g. polystyrene and acrylic).
