Dome Rooflight

This roof dome has a much lower profile than most other domes on the market. The flatter shape makes the dome stronger and most people prefer the look of a low rise dome compared to the typical "bubble" style dome (see image gallery for comparision). The cassette glazing used in the double and triple glazed domes means each of the glazing layers is separated, minimising the chance of condensation between the layers. This is the only range on the market with all sizes to benefit from cassette glazing,

Outer dome is 3mm impact resistant longlife polycarbonate which has a UV Protective coating on both sides. This coating stabilises the product to avoid discolouration and weakening due to exposure to sunlight. Where double and triple glazed domes are being used, the inner domes are 2mm thick impact resistant longlife polycarbonate sheet. Polycarbonate is light weight and has an impact strength 200 times greater than glass which makes breakage very difficult.
