High performing contemporary rooflights

Rooflights are the perfect solution for bringing extra natural light into a building interior. They are often used in brick-built extensions and loft conversions and can also be installed into stairwells or any other interior area with an external roof.

The Smart Aliver rooflight is a fixed, flat roof window made from high performing aluminium. Its sleek design is unobtrusive and can seamlessly fit into any architectural style. This makes it ideal for both contemporary property renovations and as an integral part of a new-build home.
