Transparent PVC film is very sensitive to wear and tear due to exposure to ultraviolet light and atmospheric pollution. The film will yellow over time and become brittle. The expected lifespan is greatly extended if the film is cleaned regularly and covered when not in use.
All PVC films sold by Wendt have UV blockers. This provides protection against sunburn and the harmful radiation that can cause cancer. Transparent PVC film is mainly used for outdoor sun protection and for windows in boat hoods.
