Duplus Fixed Rooflights
Contemporary styled fixed rooflights, incorporating structural silicone glazing techniques to ensure a complete, factory-finished, high-quality structure, manufactured in our UK factory. Fully watertight with a flush-glazed and elegant appearance. Suitable for both flat roofs and pitched roofs.
Our fixed rooflights are non-opening and incorporate fully enclosed double-glazed units to eliminate the risk of breakage. Traditional stepped-edge flat glass roof lights have a significantly higher vulnerability to breakage due to exposed edges.
Duplus fixed flat rooflights are double glazed in clear toughened and HEATSOAKED safety glass as standard.
We offer a range of tints:
- Blue tint
- Bronze tint
- Grey tint
Or if preferred, an obscure finish for privacy or high-performance solar control to minimise solar gain (heat) (g) and maximise light transmittance (Lt).
Easy installation & Secure
Fixed roof lights are easy to install and are provided as a fully assembled unit for your convenience. An integral perimeter gasket creates an air and water seal without the need for site-applied silicone.
The product is secured via screw fixing to the builders kerb externally and a matching cover clip is then applied to conceal the fixings.
We have a range of secure rooflight options available for both new build and renovation properties. For new build projects, we have Secured by Design (Part Q) available as an enhanced security variant.
