Many properties have extensions with flat, or near flat roofs.
Keylite has developed a Flat Roof System (FRS) specifically for flat roofs, which will allow plenty of light into the area beneath.

The Keylite FRS (Flat Roof System) provides all the benefits of ventilation, daylighting and the ability to integrate all Roof Windows within the entire Keylite range. The system is also available with Keylite Electric Operation and Smoke Ventilation Systems.

Often a flat roof leaves areas in a room where light cannot fully reach. With a Keylite FRS (Flat Roof System) you can allow light into these areas.
