LEXAN polycarbonate sheet is a perfect glass substitute. Polycarbonate sheet maintains glass-like clarity and is highly impact resistant and strong. LEXAN is approximately 250 times stronger than glass. It can be used for a variety of household projects, including replacement windows, garage windows and storm doors. Other applications include security and vandal protection. Its protective UV coating and its insulating property also make it a reliable glass alternative. Polycarbonate is lightweight and cuts easily with common tools (not included), making it easy to work with during installation.
