Our fixed rooflights incorporate fully enclosed double glazed units to eliminate the risk of breakage. Traditional stepped edge flat glass rooflights have a significantly higher vulnerability to breakage due to their exposed edges.

We offer a range of tints:
Or if preferred, an obscure finish for privacy or high-performance solar control to minimise solar gain (heat) (g) and maximise light transmittance (Lt).
Our fixed rooflight is easy to install and provided as a fully assembled unit. 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 fixed 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.

Our flat fixed rooflights are suitable for both flat and pitched roofs made of slate, tile, zinc or any other roof material, due to the independent upstand. You will need to create the upstand/kerb and then weather it with your roof material e.g. single-ply membrane, GRP, fibreglass etc. Our rooflight will then sit and seal against your weathered upstand. We provide you with all the fixings you need. You do not need any additional flashing kits with our fixed rooflights.
