The Brett Martin Flat Glass Rooflight is engineered for straightforward, secure installation on flat or low-pitch roofs. It can be installed directly onto a builder’s upstand or a PVC kerb and is suitable for fixed, manual, or powered opening formats.

Installation Guidelines

  • Roof pitch: Must be between 2° and 15°. Use the supplied pitch matrix to determine minimum pitch per size.
  • Upstand: Should be weathered and insulated, with dimensions:
    • External = Rooflight size +40 / -20 mm
    • Internal = Rooflight size -150 mm (+30 / -0 mm)
  • Minimum upstand height: 75 mm
  • Thermal caution: Blinds beneath the glazing can increase thermal stress risk. If blinds are used, choose light colours and allow space and airflow.
