Polycarbonate 25mm Heatguard Opal

Marlon ST Longlife dual tinted sheets offer dual-layer colour combinations in the same sheet to reduce heat build up and solar glare, while providing soft, diffused natural daylight.

The heat controlling outer layer is effective in reducing solar heat gain through the roof  by up to 50% , and by combining this with a light diffusing opal interior, adds to the aesthetics and ambience of any conservatory, lean-to or veranda.
