Natural light with stunning contemporary look

The flat skylight provides an element of style to extension roofs, and floods natural light into the room below.  Its distinctive sleek, frameless edge to edge glass gives a stunning contemporary look allowing the largest possible amount of light into the room.  

Sitting flush with the internal plasterboard, the flat skylight looks frameless from the inside, giving the room a bright open roof feel. The fully insulated frame with ‘warm frame’ technology combined with noise reducing glass means that flat skylight blocks out noise from the outside and is unrivalled in thermal efficiency.

The flat skylight’s simple pre-assembled design, unique click-fit installation process allows precision fit and is up to 50% faster than other flat roof lights, saving you time on site.
