  • Patent number: 4081300
    Abstract: A solar control film, for application to window glass by the consumer with minimum or no preparation, comprises a vapor deposited aluminum coat, which partially transmits light, interposed between a vinyl stratum and a polyester stratum, either of which contains an ultraviolet inhibitor and each of which is self supporting. This film is adhered by pressing the surface of its vinyl stratum against the window glass in either dry or wet condition.

  • Patent number: 4028475
    Abstract: A security film for shatterproofing windows comprises: at least two oriented polyethylene terephthalate self supporting strata having critical thicknesses for shock absorption and tensile strength, of which at least one optionally has a semi-transparent vapor deposited aluminum coat for solar control; and at least two relatively soft bonding strata having critical thicknesses for adhesion and cohesion, of which at least one is an internal copolyester stratum for bonding self supporting strata together and one is a pressure sensitive stratum at the outer surface of the film for application to window glass.

  • Patent number: 3956559
    Abstract: A solar control safety window, for example, a windshield, comprises a vapor deposited aluminum coat in a laminated sheet assemblage that is bonded between two sheets of glass. Materials are disclosed for effective bonding. The aluminum coat partially transmits light specifically, while it largely reflects radiation generally, in order to provide a safety window with optimum radiation control.

  • Patent number: RE28883
    Abstract: .[.A solar control film for application to window glass comprises a vapor deposited aluminum coat, which partially transmits light, interposed between a pair of moisture permeable polymeric strata, each of which is self supporting. In one modification, an optional outer coat on one of the polymeric strata is composed of a pressure sensitive adhesive in association with a silicone release sheet. In another modification, an optional outer coat on the other of the polymeric strata is composed of a silicone release agent..]..Iadd.
