Coxdome Lumiglaze Glass Rooflight Manual opening
Product details
Lumiglaze – Flat Glass – Manual Opening
The COXDOME Lumiglaze Flat Glass Manual Opening Rooflight is engineered for both performance and style. It incorporates a double-glazed unit within a slim aluminium frame and sits on a 160 mm PVC-u upstand. A thermal break in the upstand ensures excellent insulation and minimises condensation. The powder-coated frame delivers a sleek, durable finish, with sizes from 600 mm to 1500 mm.
The rooflight’s clean, contemporary design lets in generous daylight while offering panoramic sky views. Its toughened outer pane is finished with a ceramic edge coating, and the insulated upstand suits new build or retrofit applications.
A discreet manual opening mechanism allows for controllable ventilation without compromising the slim profile. The frame’s internal thermal break improves energy performance, and all fixings are hidden under a flush cover.
