Minimalistic Design

A Flat Skylight is a great way to incorporate bright natural light into a home or extension project. These structures have slim sightlines that blend seamlessly with the roof. In this way, they feel like a natural addition to the home and offer plenty of high-performance benefits.

There is a neat, mitred external finish with the aluminium surround. This is bonded to the glass to further enhance the chic aesthetics. Our Flat Skylights come as standard in grey, black or white but they can be requested in bespoke RAL colours if desired.
