When upgrading a flat roof extension or orangery, the right roof lantern can completely transform the look and feel of your living space. Brett Martin is a British manufacturer renowned for engineering daylighting systems that combine aesthetic elegance with robust structural integrity.
Every Brett Martin roof lantern features slim, powder-coated aluminium rafter bars engineered to reduce visual intrusion and maximise daylight. Designed for the UK climate, they exceed building regulations for thermal efficiency, safety, and weatherproofing.
To complement your home’s architecture, Brett Martin roof lanterns come in three distinct structural designs:
The modern favourite for rectangular extensions. With a clean, minimalist 4-pane layout, this design eliminates unnecessary hip rafters for unobstructed views of the sky.
Ideal for larger extensions, dining spaces, and orangeries. The 6-panel design adds extra glazing bars for a more decorative, traditional aesthetic that mirrors classic period architecture.
Purpose-made for square or near-square roof openings. The 4-sided pyramid lantern delivers symmetry and balanced light distribution while offering exceptional value.

Brett Martin roof lanterns are designed to fit directly onto a prepared builder’s upstand (timber kerb). The upstand should generally be constructed at a minimum height of 150mm above the finished roof membrane and angled between 0 and 5 degrees for optimum drainage and aesthetic balance. Always measure the overall external dimensions of your finished timber upstand before ordering.

Yes, and Brett Martin provides laminated inner glass as standard. Under UK safety regulations for overhead glazing, if glass breaks, toughened glass can drop down in small pieces. Laminated inner glass bonds to an interlayer on impact, staying in place to protect occupants below and maintain security.
