Roof light systems to enhance natural light

Roof lights are a great way to bring more natural light into a building interior. They are often installed into flat roofs and are a popular addition to all types of extensions. Our roof lights can be incorporated into the design of a new build extension or can be retro=fitted into an existing orangery or conservatory. They are available in a selection of styles, shapes, and sizes to meet your requirements. With excellent insulating capacity and the option for solar control or frosted glazing, roof lights are a popular choice for UK homeowners.

As installers of both PVCu and Aluminium to the New Build market, the importance of on time delivery is totally time critical.
Over the last 20 years Quantum windows have worked closely with PGB to partner with us and deliver our offer to site.
Highly professional, and a pleasure to have worked with them so closely over the years.
