16mm Opal Polycarbonate SheetsAny size up to 2.1m x 6m (width x length)Lightweight, tough and thermally efficient roofing panels!Opal-tinted multi-wall polycarbonate allows light in to keep it bright but reduces solar gain concentrating on one area. Eliminates uncomfortable hot-spots, creates softer light quality and provides privacy.16mm polycarbonate sheets are great for carports, pergolas and greenhouses. For large applications, such as conservatories, a thicker 25mm or 35mm polycarbonate is recommended.Polycarbonate is a great insulator that also reduces condensation and diffuses light. It can also be more energy efficient than glass of a comparable thickness and up to 50% cheaper.Features & Benefits UV Resistance - minimises long-term yellowing High resistance to impact - resistance to breakage Super thermal efficiency - triplewall and fivewall Robust yet lightweight - fraction of glass weight Fire safety - Class 1 Spread of Flame Protection 10 year warranty - light transmission is guaranteed
