Understanding the Brett Martin Flat Rooflight System
Brett Martin Flat Rooflights are manufactured using a thermally broken aluminium frame paired with high-performance, double-glazed glass. The internal pane is laminated for safety, while the external pane is toughened for durability. This combination delivers excellent insulation, safety and longevity.
The rooflight is designed to sit on a builder’s upstand or proprietary kerb, creating a low-profile, contemporary finish that sits neatly above the roof surface. Available in fixed, manual opening or electrically opening options, the system suits a wide range of applications. View the full Brett Martin Flat Rooflight range.
Preparing the Roof Opening and Upstand
Correct preparation of the roof opening is critical to a successful installation. Brett Martin rooflights are typically installed onto a timber upstand with a minimum height of 150mm above the finished roof level.
Before installation, check that:
– The upstand internal dimensions match the ordered rooflight size
– All sides are square, level and structurally sound
– The waterproof membrane is fully dressed and sealed up the upstand
For more detailed guidance, refer to our flat rooflight upstand requirements page.
Positioning the Rooflight on the Upstand
Once the upstand is prepared, the rooflight can be positioned. Brett Martin Flat Rooflights are supplied fully assembled.
Steps:
1. Lift the rooflight into position using appropriate equipment
2. Carefully place it onto the upstand
3. Check alignment and level
4. Fixing the Rooflight Securely
Fix through the pre-drilled fixing points using suitable fixings for the upstand material. Tighten evenly to avoid frame distortion.
Weatherproofing and Sealing
Apply the recommended sealant between the rooflight frame and the upstand. Dress the roof membrane neatly up to the frame and ensure all junctions are fully sealed.
