Circular Rooflight

Architects are increasingly turning to circular rooflights to make a visual statement in contemporary interior designs. Brett Martin Circular Glass stands out as a premium round rooflight, sought after for its unique style. It's offered in various sizes for mounting onto a builder's upstand or as a complete unit with a pre-fabricated kerb. This modern glazing solution offers a sleek internal appearance, a subtle exterior presence, and evenly spreads daylight throughout interior spaces.

Fitting and Measurements

Please refer to the installation guide in the ‘Downloads’ tab on this page.

When buying a 900mm diameter rooflight from the website for installation on your own upstand, ensure that the external upstand dimensions match the 900mm diameter. Opting to purchase with a GRP kerb at the same size of 900mm means that your structural opening should also measure 900mm.
