Flat Rooflight FAQ
-
What is the best type of rooflight for a flat roof?
When it comes to flat roofs, the best type of rooflight balances thermal performance, durability, and aesthetics. A glass rooflight housed in a thermally broken frame offers a robust, long-term solution by minimising heat loss and preventing condensation.

- Can rooflights be installed on pitched roofs?
Yes. While flat rooflights are designed for flat roofs, they can also be installed on pitched roofs up to 70° when fitted with a suitable timber or concrete upstand. We offer custom rooflight solutions to accommodate various roof types and angles.
-
Is there a rooflight that helps prevent heat build-up?
Yes, to reduce heat build-up we offer rooflights with solar control glass. These rooflights are specially designed to absorb heat and reflect a portion of UV rays. This helps maintain a cooler indoor temperature during warmer months, especially in south-facing or exposed areas.
What is a wall-abutted rooflight and when should I use one?
A wall-abutted rooflight is a glazing system installed at the junction where a roof meets a vertical wall—often used in eaves glazing or lean-to extensions.
