Unlike other glazing materials, multi wall polycarbonate sheet is virtually unbreakable and provides as much as 60% more thermal insulation than glass. Its light weight, durability, strength and ease of installation make it the ideal glazing material, especially for outdoor applications. Structured polycarbonate sheet is the most versatile structured thermoplastic available today. A co-extruded protective layer guarantees the highest stability against the harsh effects of the sun's rays and the multi-walled design gives a stable weathering surface.
