This remarkable, highly insulating glazing material is manufactured from damage-resistant polycarbonate and has added co-extruded long life protection from the effects of UV rays. 35mm Polycarbonate sheet has very high impact resistance, fine optical clarity and excellent fire performance. A high performance UV absorption layer means longer life and prevention of yellowing and loss of strength. Polycarbonate offers excellent protection against vandalism and accidental damage with an impact resistance up to 200 times greater than glass. This characteristic is maintained over a broad temperature range and prolonged service life.

Dual Tinted Polycarbonate Sheeting

Offering dual-layer colour combinations in the same multiwall polycarbonate sheet reduces heat build up and solar glare while providing soft, diffused natural daylight. A heat controlling outer layer is effective in reducing solar heat gain through the roof by up to 50%. By combining this property with a light diffusing opal interior it adds to the aesthetics and ambience of any conservatory, lean-to roof or veranda. Dual tint options include Heatguard and Bronze Opal to provide a comfortable cool and naturally lit interior space.


Heat guard is a special treatment that is built into the top side of the polycarbonate sheet. This serves to reflect the suns rays helping to reduce heat build up within the roof by up to 50%. The internal face of the polycarbonate sheet is opal tinted giving excellent reflective internal light.


Bronze-Opal is a dual coloured polycarbonate sheet with a bronze outer surface and an opal tinted inner surface giving excellent reflective inner light.
