Coxdome Lumiglaze Glass Rooflight - Fixed
Product details
Lumiglaze – Flat Glass – Fixed
The COXDOME Lumiglaze Flat Glass Fixed Rooflight combines solid build quality with understated design. It uses a double-glazed glass unit set within a slim aluminium frame and a 160 mm PVC-u upstand. A thermal break within the upstand and frame boosts insulation and helps prevent condensation, while the powder-coated finish ensures long-lasting good looks. Sizes range from 600 mm to 2200 mm.
Its wide, flush-fitted glass surface floods interiors with natural light and offers unobstructed views of the sky. The toughened glass outer pane features a ceramic edge coating, and the insulated upstand is suitable for both new and existing openings in flat roofs.
Energy performance is enhanced by the frame’s internal thermal break, and all fixings are hidden under a flush cover for a tidy, secure finish.
