A breathable film cover for transparent plastic plates (12) employed as windows and the like. A metalized plasticized polyvinyl chloride film (18) is adhesively laminated to a polycarbonate or polyacrylate plate by means of an adhesive (16) having a UV absorber. The plasticized PVC film allows for the escape of moisture emanating as a result of degasification of the polycarbonate or polyacrylate plates. The permeability of the PVC or polyvinyl chloride film to moisture allows the metalized plasticized polyvinyl chloride film to remain adhered to the plates without bubbles, craters or tunnels.
