Polytite Door Systems are made with triple-walled polycarbonate panels that are strong yet lightweight, providing easy operation with minimum stress on hardware components. The translucent panels provide a naturally-lit, inviting work environment and help reduce winter heating costs through the effects of solar heat gain. The panels are also extremely impact-resistant and can withstand long-term exposure to extreme elements such as sun, wind, rain and snow without cracking or splitting. Particularly suited for service garages but ideal for all types of industrial, agricultural, commercial, institutional and residential overhead door installations where an attractive, light-transmitting, strong, lightweight door is desired.
