An Overview: What Are Brett Martin Flat Rooflights?
Brett Martin flat rooflights are contemporary, fixed-glass units designed for installation on flat or low-pitch roofs. They are manufactured by Brett Martin Daylight Systems, a division of the larger Brett Martin brand known for delivering high-quality plastic and glass construction products throughout the UK and internationally.
These rooflights are made to let in natural light while maintaining excellent thermal performance and weatherproofing. Ideal for both residential and commercial use, they provide an efficient way to enhance a room’s brightness without sacrificing comfort or energy efficiency.
Key Product Features
1. Glazing and Materials
One of the standout features of Brett Martin flat rooflights is the use of high-performance glass and robust framing materials. Each unit includes:
- Double-glazed low-E toughened glass as standard
- Optional triple glazing for enhanced thermal insulation and noise reduction
- Aluminium outer frames with a powder-coated finish for durability
- PVC-U internal frames, providing insulation and low maintenance
The combination of these materials delivers a strong, energy-efficient unit that also meets aesthetic expectations. The external aluminium profile ensures resistance to the elements, while the PVC-U interior complements modern interiors with clean, minimalist lines.
2. Thermal Performance
Energy efficiency is a major concern in both new builds and renovations. Brett Martin rooflights are designed with thermal performance at the forefront. Standard double-glazed units offer U-values as low as 1.2 W/m²K, while triple-glazed options can achieve even lower values, ideal for projects targeting stringent insulation standards.
The use of low-emissivity coatings and warm-edge spacers between panes helps to minimise heat loss, making these rooflights suitable for both domestic properties and commercial buildings with energy efficiency requirements.
3. Weather Resistance and Drainage
These rooflights are engineered for flat roof applications and are tested to meet or exceed British Standards for weather tightness. They include:
- Seamless kerb integration, minimising water ingress
- Integral drainage systems, designed to channel rainwater away from the glass
- Wind and watertight seals, with high-grade gaskets to prevent drafts
This makes them particularly suitable for exposed sites or high-rainfall areas. Unlike some basic rooflight models that rely heavily on flashing and sealant, Brett Martin’s design focuses on a long-lasting, low-maintenance seal.
4. Ease of Installation
Ease of installation is one of the biggest advantages of this product range. Brett Martin rooflights come as fully assembled units, including the insulated upstand (kerb), which eliminates the need for site-built frames or secondary fixings.
Key installation benefits include:
- Factory-glazed units, reducing time on-site
- Fully compatible with most flat roof membranes, including GRP, EPDM, and bitumen
- Pre-formed kerb, ensuring proper drainage angles and airtightness
This plug-and-play approach is especially helpful for contractors working to tight timelines, and it simplifies the ordering process for self-builders and renovators.
Design Considerations and Sizes
Brett Martin flat rooflights are available in a wide range of sizes to suit most applications, from small bathrooms to large kitchen extensions. The minimalist, frameless internal view maximises visible glass area, while the external profile maintains a low profile that blends neatly into flat roofscapes.
Although the standard finish is anthracite grey externally and white internally, custom RAL finishes may be available for specific orders, making it easier to coordinate with individual architectural designs.
Whether you’re aiming for a contemporary minimalist look or seeking to add light to a more traditional structure, the understated design ensures these units complement a variety of aesthetics.
Ideal Use Cases
These rooflights are a versatile solution for multiple property types and functions:
- Single-storey extensions – bringing daylight into deep-plan kitchens or living spaces
- Commercial properties – offering bright, naturally lit workspaces with minimal visual intrusion
- Bathrooms or stairwells – where privacy and overhead light are both essential
- Educational or healthcare settings – to meet wellbeing and daylight standards without increasing energy loads
With fixed, non-opening designs, Brett Martin rooflights are particularly suited for spaces where ventilation is not a primary concern but where maximum natural light is desired.
Compliance and Certifications
Brett Martin flat rooflights comply with a range of UK building standards:
- BS EN 1279 – for insulating glass units
- BS 6375 – for weather tightness and resistance
- Part L compliance – in support of energy efficiency in new and existing buildings
Additionally, many models are tested for impact resistance, an important consideration in high-traffic commercial areas or buildings with public access.
