New Lexan® solar control solid and multiwall sheet controls heat and allows high level of light
Current architectural design calls for building glazings that permits high levels of natural light, for both aesthetics and to reduce energy for interior lighting. However, intensive use of glazing can lead to rapid interior heat buildup due to penetration of near-infrared (IR) radiation (solar transmission) through the glazing, especially in hot and sunny climates. This, in turn, can raise energy costs for cooling the building.

Previous solar-control glazing, the only polymer alternative, used a screen-printed coating or a co-extruded layer on one side of the sheet to absorb IR transmissions. But the coating and co-extruded layer made the glazing translucent – at best – or opaque, greatly reducing light transmission. Hence, architects who wanted to use polymer glazing had to choose between light transparency and solar control. They could not find both properties in one product unless they went to expensive solar controlled glass.
