Designed for Maximum Light

Brett Martin roof lanterns are engineered with minimal framework to maximise the glazed area, which helps natural light to flood your space. We stock contemporary 4-pane designs for near-uninterrupted views, and 6-pane lanterns for a more traditional look with additional structural detailing.

This reduction in visible framework helps create brighter interiors and a stronger architectural focal point – ideal for open-plan kitchens, dining areas, living spaces – or anywhere, really!

Proven Thermal Performance

Brett Martin roof lanterns are built with a fully thermally broken aluminium frame and high-performance double glazing, which means improved insulation and reduced heat loss.

• Low-E coated glass to retain internal heat
• Argon-filled units to improve insulation
• U-values as low as 1.2 W/m²K 

This helps your home retain heat all year round, while helping you meet 2026’s updated building regulations.

Built for Safety, Strength & Longevity

We recommend Brett Martin roof lanterns for both residential installations and larger-scale commercial applications because they’re engineered to perform in real-world conditions:

• Toughened outer pane with optional or standard laminated inner pane for overhead safety
• Tested for wind and snow loads to relevant British Standards
• Powder-coated aluminium frames for extra long-term durability

A Choice of Sizes, Configurations & Finishes

• 4-pane contemporary and 6-pane classic configurations
• Standard sizes from approx. 1500mm x 1000mm up to 3000mm x 2000mm, plus bespoke sizing
• Frame colour options including grey (RAL 7016), white (RAL 9010), and black (RAL 9005) inside and out

And Two Advanced Glazing Options

• Clear self-cleaning glass for maximum daylight
• Blue solar-control glass to reduce glare and solar gain

This allows you to balance brightness, temperature control, and aesthetics – depending on your space and vision.
