Abstract
Sandwich unit for a heat insulating wall coating having a surface layer facing the room confined by the wall, an intermediate layer adhered to the surface layer and being of plastic foam, and a third layer adhered to the intermediate layer and facing the wall. The third layer comprises an electrically insulating plastic foil and metal flakes embedded in the plastic foil and thereby electrically insulated from each other. The flakes are disposed with their broad side parallel to the foil and overlap each other to form an unbroken total surface for reflecting heat radiation.

A heat transfer resisting sandwich unit for wall coating, comprising in combination a surface layer facing the room bounded by the wall to be coated, one intermediate layer adhered to said surface layer and being of plastic foam, and a third layer adhered to said intermediate layer and facing the wall, said third layer comprising an electrically insulating plastic foil and metal flakes embedded therein and electrically insulated one from another by said plastic foil, said flakes being oriented with their broad side parallel to the foil in a manner known per se, said flakes further disposed in overlapping relation and therewith cooperatively forming an unbroken total surface for reflecting heat radiation thereon.
Sandwich unit for wall coating, comprising a surface layer facing the room confined by the wall, one intermediate layer adhered to said surface layer and being of plastic foam, and one third layer adhered to the intermediate layer and facing the wall, in which the third layer comprises an electrically insulating plastic foil with metal flakes electrically insulated from each other and enclosed therein, said flakes being orientated with their broad side parallel to the plastic foil, said flakes overlapping each other and in plane projection forming an intact reflecting surface in which the intermediate layer consists of foamed-up polyester with gas filling of argon or freon in relation 50% enclosed and 50% open cells.
Sandwich unit for wall coating, comprising a surface layer facing the room confined by the wall, one intermediate layer adhered to said surface layer and being of plastic foam, and one third layer adhered to the intermediate layer and facing the wall, in which the third layer comprises an electrically insulating plastic foil with metal flakes electrically insulated from each other and enclosed therein, said flakes being orientated with their broad side parallel to the plastic foil, said flakes overlapping each other and in plane projection forming an intact reflecting surface in which the intermediate layer of foam plastic is of a thickness of approximately 4-6 mm, and the plastic foil is of a thickness of about 0.2 mms.
