Aliver Rooflight

Bringing natural light into the home all year round, the high-performance, high quality Aliver Rooflight system is a fixed, flat solution which creates a contemporary look for any property.

Providing exceptional thermal insulation, light transmission and noise reduction, the system has been designed to accept both double and triple glazed units.

Featuring an elegant and unobtrusive aluminium frame and a unique, concealed fixing system which makes the rooflight fast and easy to install, the system has also been designed such that the glazing unit may be taken out of the frame and replaced, without the frame itself having to be removed, providing a durable, cost-effective and long-life solution.
