Glazing

Many individual factors need to be taken into consideration when specifying your rooflight: thermal efficiency, light transmission, solar gain, fire classification, and noise reduction are just some of these factors. The glazing you choose will have a major impact on how your rooflight performs.

The Trade Range Domes are manufactured from polycarbonate. Polycarbonate is a durable, high impact- resistant material and is highly transparent to visible light. In some cases it can achieve better light transmission than many kinds of glass and can be up to 300 times more impact resistant than glass. Trade Range Domes are available in Double, Triple and Quadruple skin and can be supplied Clear, Diffused, Opal or Cool and Clear. The Trade Range Domes are manufactured in accordance with European standards and hold full CE marking according to EN 1873.
