Virtually unbreakable with 250 times the impact strength of glass and 30 times that of acrylic, polycarbonate is the perfect light weight material for applications such as skylights, covered walkways and replacement windows for screen doors.
Polycarbonate provides up to 25% better thermal insulation than single-panel glass and UV-resistant grades are available to protect from weathering.
