Marlon ST - 35mm polycarbonate sheet, has great rigidity, strength, and insulation properties. This sheet is used on structures where the primary concern is the insulation, but light transmission is still required such as in a conservatory roof. The most popular colour in this range is the white as opposed to the clear because it provides shading for conservatories in the summer to minimise heat gain from getting to unbearable levels. Specification: Weight: 3.8 kg/sqm Insulating U Value: 1.2 Light Transmission: Clear = 63% Bronze = 15% White = 40%
