UV resistant polycarbonate plastic sheets combine the impact strength of general purpose polycarbonate plastic sheets with a proprietary UV-resistant surface treatment on both sides that protects it from weathering. UV polycarbonate plastic sheets are the only polycarbonate glazing material backed by a ten-year limited warranty against yellowing, loss of light transmission, and breakage. UV resistant polycarbonate plastic sheets are well suited for all types of vertical glazing and overhead applications such as skylights, covered walkways and barrel vaults.
