Single glass panel look
The single-panel format is built around a cleaner, flatter rooflight profile rather than a raised lantern shape.

Maxi-Flat Rooflight
A single-panel flat rooflight for flat roofs. Uninterrupted views, no dividing bars, self-cleaning glass as standard, and a 5-day express manufacturing lead time.
Flat Rooflight Fit
A flat rooflight is the lower-profile route for bringing light into an extension without making the glazing a raised feature. It is often the better choice where planning, roof height, neighbouring views, or a clean contemporary roofline matter.

Best when the roofline needs to stay quiet
A flat rooflight is the lower-profile route for bringing light into an extension without making the glazing a raised feature. It is often the better choice where planning, roof height, neighbouring views, or a clean contemporary roofline matter.
Best fit for
- Single-storey extensions where a raised lantern would look too prominent
- Rooms needing overhead light without a strong external roof feature
- Projects where the roof finish should stay clean and simple
What we check on survey
- We check kerb height, roof fall, and drainage before confirming suitability.
- We discuss solar-control glass where the room faces strong sun.
- We confirm whether a fixed or opening unit is the better route.

Rooflight Design
Why A Flat Rooflight Feels So Clean
This range focuses on a flatter, lower-profile glazed roof option for extensions where the cleaner roofline is the priority.
Cleaner external roofline
It is a better fit where the project needs light from above without the stronger visual statement of a lantern.
Colour and vent upgrades
Custom colour routes, self-cleaning glass, and vent options can be added depending on the final room specification.
