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 roof lights are 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.

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.
