This polycarbonate sheet maintains glass-like clarity while also being highly impact resistant and strong, approximately 250 times stronger than glass. 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. It can be used for a variety of household projects, including replacement windows, garage windows, skylights and storm doors, security and vandal protection.
