Custom Size Glass Roof Lantern

Benefits

Designed to maximise natural daylight, the Brett Martin Roof Lantern creates a bright, open feel while delivering strong thermal performance for modern homes and extensions. Slim aluminium profiles provide clean sight lines, while the thermally broken frame and Low-E double glazing help reduce heat loss. The self-cleaning outer glass minimises maintenance, and quick installation onto a prepared builder’s upstand helps save time on site.

Features

The roof lantern is available in 4-pane or 6-pane layouts and comes in 9 standard sizes, ranging from 1500 × 1000mm to 3000 × 2000mm. Each unit is supplied with a toughened inner pane as standard, with an optional laminated inner pane available for enhanced overhead safety. Manufactured in the UK, the roof lantern is supplied with a 10-year warranty.

The Brett Martin Roof Lantern is engineered for quick, straightforward installation on flat or low-pitch roofs, mounting directly onto a prepared builder’s upstand.

Installation guidelines

• Roof Lantern should be installed by competent roofing contractors following Brett Martin’s installation guide and all relevant health & safety legislation.
• These rooflights should be considered FRAGILE. A risk assessment must be carried out to define appropriate fall-protection measures in line with CDM regulations and Rooflight Association guidance.
• Install onto a fully insulated and weathered builder’s upstand. The roof covering must dress up the sides and over the top of the upstand with a level, obstruction-free bearing surface.
• External upstand dimensions should match the ordered rooflight size, with a tolerance of +20 mm / -0 mm in both directions.
• Minimum upstand height: 150 mm. Minimum upstand width: 85 mm to provide a suitable fixing surface.
• Suitable for upstand pitches from 0° to 5°. For aesthetic reasons Brett Martin recommend constructing the upstand level (0°); a pitched upstand may result in a “lopsided” appearance.

Laminated vs toughened inner panes

• Laminated inner panes help prevent glass from falling into the space below if breakage occurs, offering enhanced overhead safety.
• Toughened inner panes may be used in certain locations subject to a satisfactory risk assessment in accordance with British Standards and Rooflight Association guidance.
• Where blinds or other fittings are installed in the lightwell, they should be positioned as far as practicable from the glass and preferably in light colours to reduce the risk of thermal stress fracture to laminated glass.
