<div class="htmlview paragraph">This paper discusses a new technology for control of solar heat gain in automobiles. Described will be a non-metallic, all-polymeric film, which reflects solar infrared, has high visible light transmission, and an appearance that is clear and colorless.</div> <div class="htmlview paragraph">The film is designed to be used in combination with tinted glass, as a component in an overall glazing design. Measured solar control levels are shown to be competitive with metallised film technologies.</div> <div class="htmlview paragraph">Prototype windshields and body glass units have been successfully made in a standard autoclave cycle. Constructions were made by using the film as the center component in a five layer glass/pvb/film/pvb/glass laminate. The results of durability, performance, and specification tests are encouraging and will be discussed.</div>
