Slimline aluminium roof lanterns for flat and low-pitched roofs

Brett Martin’s roof lantern floods flat-roofed extensions and open-plan living spaces with daylight through a slender, thermally broken aluminium frame designed to maximise glass area. Supplied with four panes of glass as standard for a clean, contemporary look – with the option of six panes for a more classic aesthetic – it combines a slimline profile with Low-E insulated double-glazed units achieving a centre-pane U-value of 1.2W/m²K. The frame is available in grey, white, black and dual-colour finishes, and the streamlined design simplifies installation without the extensive use of silicone sealant. A 10-year warranty is available.
