  • Patent number: 4973511
    Abstract: A laminated window construction includes a solar control film formed by a flexible plastic substrate such as a PET sheet having on one surface a multilayer solar coating. This multilayer solor coating includes at least one thin layer of metal and at least one adjacent adherent layer of a dielectric material. An energy absorbing safety film of the type normally used in shatterproof glass laminates (e.g., plasticized PVB) is bonded to at least one side, and preferably both sides, of the solar control film to form a composite solar/safety film. This composite solar/safety film is specially designed to contribute, after incorporation into a glass laminate, no more than about two percent of visible reflection (based on total incident visible radiation) which has the effect of substantially masking the visible effects of wrinkles in the solar control film substrate (i.e., the wrinkles are made less visible).
