Brett Martin Circular Glass Rooflight
Distinctive Design
Sizes from 600mm to 1500mm
Powder Coated Aluminium
38dB Rw Acoustic Performance
Brett Martin Circular Glass is a premium round rooflight designed to create a distinctive architectural feature while bringing soft, even daylight into the space below.
Its circular shape offers a different look to standard square or rectangular rooflights, making it ideal for modern homes, entrance areas, landings and design-led projects.
With a powder coated aluminium frame, laminated Low-E glass, concealed fixings and optional insulated GRP kerb, it combines visual impact with the practical performance expected from a high-quality flat roof glazing product.
A Round Rooflight with Real Design Impact
Ideal for statement spaces where natural light and architecture work together.
Brett Martin Circular Glass is designed for projects where the rooflight is part of the visual story, not simply a practical opening in the roof. Its clean circular shape creates an attractive shaft of daylight and can soften the geometry of contemporary interiors.
Used above a stairwell, hallway, kitchen island or seating area, it can become a subtle but memorable feature. The product uses a thermally isolated aluminium frame powder coated to RAL 7016.
The glazing includes a toughened outer pane, argon-filled cavity and laminated Low-E inner pane, helping deliver good thermal performance while supporting overhead safety.
All fixed units use concealed colour-matched fixings for a neat finish.
Circular Glass is suitable for flat roof applications with the correct pitch and can be mounted directly to a structural insulated builder’s upstand or supplied with a prefabricated 150mm insulated GRP kerb. This makes it suitable for both new-build and refurbishment projects where a more distinctive daylight solution is required.
Benefits
Circular rooflights are excellent when you want more than a standard glazing opening. Their round shape helps daylight spread evenly and gives the room below a more considered, designed feel.
They work especially well above stairwells, entrance halls, central kitchen zones and spaces where a square rooflight would feel too predictable.
Brett Martin Circular Glass keeps the external appearance minimal while offering practical options for direct fixing to a builder’s upstand or supply with a 150mm insulated GRP kerb. The laminated inner pane, non-fragility testing and concealed fixings all help provide reassurance as well as style.

Bespoke Round Rooflight Pricing
Specified around diameter, kerb choice, glazing and project conditions.
Circular Glass pricing depends on the rooflight diameter, whether a GRP kerb is required, the glazing specification and any bespoke requirements.
View Glazing can provide advice on whether a circular rooflight is the best option for your space and prepare a quotation based on your chosen size and installation details.
Because circular rooflights are often used as a design feature, it is worth considering the internal lightwell, ceiling finish, roof pitch and room layout early so the rooflight lands exactly where it will have the strongest visual impact.
