The Coxdome Trade Range is a high quality, universal, ‘out of plane’ rooflight system.

This range is available in a variety of options and sizes, and whether you’re a roofing contractor, architect, building contractor or a residential client there is an dome available for all flat roofing requirements.

These domes are supplied complete with a 150mm splayed white PVCu upstand, and are available in double or triple skin polycarbonate glazing versions.

Installed to the manufacturer’s instruction the Trade Range offers excellent waterproofing properties. Weathered to the full height of the upstand water penetration is virtually impossible.

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

In areas which are difficult to access or in areas where security is primary consideration ‘non-controllable’, permanent ventilation offers continuous ventilation around the perimeter of the dome. Ventilation spacers (supplied) can be inserted between the factory assembled polycarbonate dome and the upstand during installation. The shaped lip on the edge of the outer skin is engineered for maximum weathering and prevents water ingress.

The Coxdome 150mm PVCu Upstand (included) is designed to provide a watertight thermal break between the finished structured roof and the rooflight. With excellent thermal insulation properties they offer a more thermally efficient solution to the standard builder’s kerb and help improve the overall ‘U’ value of the unit.
