BBA approved
Laminated Glazing
Contemporary Design
Brett Martin Flat Glass is a sleek, contemporary rooflight for flat roofs, designed to bring natural daylight into modern homes, extensions and commercial buildings without the raised profile of a traditional lantern.

A Clean, Modern Rooflight for Flat Roofs
Slim, secure and thermally efficient glazing for extensions, renovations and new-build projects.
Brett Martin Flat Glass has been designed as a modern alternative to bulkier roof glazing. Its slim aluminium frame and flush glass panel create a neat external appearance while allowing daylight to drop cleanly into the room below. The result is a rooflight that works particularly well in modern kitchen extensions, open-plan living areas and contemporary refurbishments.
The range gives you several specification routes. It can be mounted directly to a prepared builder’s upstand, supplied with a standard 150mm PVCu kerb, or supplied with a taller 300mm kerb where extra height is required for refurbishment projects.
Fixed, vented, manual opening and powered opening options mean the product can be tailored to the way the room will be used. Performance is a major part of the appeal.
Fixed Brett Martin Flat Glass rooflights have BBA approval, Secured by Design accreditation and non-fragility testing when installed to manufacturer guidance.
The laminated inner pane also supports overhead safety, making this a strong option for domestic and commercial flat roof projects where quality and reassurance matter.
Benefits
Flat Glass is one of the most versatile rooflights in the Brett Martin range. It offers the clean appearance that many homeowners and architects prefer on contemporary extensions, while still providing practical choices around ventilation, kerb height, colour and glass specification.
It is especially well suited to kitchens, dining rooms, bathrooms, landings and living spaces where extra daylight is needed but the roofline needs to remain simple and understated.
Fixed options provide a strong, low-maintenance daylight solution, while manual and powered opening options can help improve ventilation in selected spaces.

Made-to-Measure Rooflight Pricing
Flat Glass rooflights are specified around your roof opening and project requirements.
Pricing depends on size, fixed or opening operation, kerb type, glazing choice, frame colour and whether ventilation, security grille or control accessories are required.
View Glazing can help you compare the options and provide a quotation based on your project drawings or roof opening measurements.
For best results, confirm the roof build-up, pitch, internal ceiling detail and access requirements before ordering. This ensures the rooflight, kerb and glazing specification are correct for the property and installation conditions.
