A translucent, impact-resistant thermoplastic used for sunroom and screen-room roofing, with UV-stabilized grades for long-term clarity.
Definition
What polycarbonate (multi-wall) actually means.
Multi-wall polycarbonate sheets are the most-common translucent roofing material for sunrooms and screen rooms. The material is impact-resistant, lightweight, and UV-stabilized (in premium grades) to maintain clarity over the product's warranty period. Entry-level polycarbonate yellows in 8–10 years under North Georgia sun; premium UV-stabilized polycarbonate maintains clarity for the warranty period and beyond.
