Product overview

Glass Roof Lantern

A double-glazed aluminium roof lantern for flat-roof extensions, kitchens, dining areas and open-plan living spaces. Choose the Contemporary 4-pane layout for larger glass panels and fewer glazing bars, or the Classic 6-pane layout for a more traditional architectural appearance.

✓
Two selectable layouts Choose Contemporary 4-pane or Classic 6-pane to suit the look and daylight balance of your project.
✓
Thermally broken aluminium frame Helps reduce heat transfer while providing a strong, durable roof lantern frame.
✓
Selectable glass configurations Available configurations include toughened-over-toughened and toughened-over-laminated glass, subject to the selector.
✓
Suitable for flat-roof projects Designed for extensions, kitchens, dining areas and open-plan living spaces.

Choose your specification

Layout Contemporary 4-pane or Classic 6-pane roof lantern.
Size The online selector shows available configuration sizes. Current standard configurations range from 1500mm × 1000mm to 3000mm × 2000mm; bespoke sizes are available on request. Dimensions refer to the external builder’s upstand.
Glass Select the available toughened-over-toughened or toughened-over-laminated configuration. The laminated inner pane helps hold the glass together if damaged.
Thermal performance The manufacturer quotes a centre-pane glazing U-value of 1.2 W/m²K, measured vertically. This is a centre-pane figure rather than a whole-roof-lantern U-value.
Installation Designed for installation on a prepared, weathered builder’s upstand. Follow the installation guide and use a competent contractor.
Planning Planning permission and building-regulation requirements depend on your project; check with your local authority before ordering.

Product FAQs

Frequently asked questions

Clear answers to common questions about specification, glazing and installation.

What glass options are available?

Choose the available toughened-over-toughened or toughened-over-laminated configuration in the product selector.

What is the difference between laminated and toughened glass?

Laminated glass uses bonded layers and an interlayer that helps hold the glass together if damaged. Toughened glass is heat treated for strength and breaks into small pieces if damaged.

What is toughened-over-laminated glass?

It combines a toughened outer pane with a laminated inner pane for additional overhead safety where available.

When should I consider blue solar-control glass?

Blue solar-control glass can help reduce glare and solar heat gain on sun-exposed roofs. Contact the team if you need help selecting the specification.

Roof Lantern
I’m picky about finishes - this passed the test. We went for 2000 x 1500 with Grey outside / White inside. Minor note: a one‑page quick-start guide in the box would be handy, but our installer was fine.

Thank you for your review. We’re delighted to hear you’re happy with the finish and colour combination of your 2000 x 1500 rooflight. We also appreciate the helpful feedback about a one-page quick-start guide and will take this on board. Thanks again for choosing Daylight Systems.
Roof Lantern
I bought a Brett Martin roof lantern to replace a frameless rooflight from another brand that I got not long ago, and it was nothing but hassle. The difference is night and day. The build quality is great, and the customer service was really helpful throughout.

For anyone thinking about buying a roof lantern, don’t make the same mistake I did. Buy from Daylight Systems as you’re buying directly from Brett Martin themselves. Couldn’t be happier.

Thanks for leaving this review - we’re really pleased you made the switch and that the difference has been so noticeable.

It’s great to hear the build quality and our support team both stood out, especially after a frustrating experience elsewhere. And you’re absolutely right: ordering from Daylight Systems means you’re buying direct from Brett Martin. Thanks again for the recommendation - we really appreciate it.
Glass Roof Lantern
Bought a Glass Roof Lantern (1500 x 1000) in the 4 Pane Contemporary style with white interior / grey exterior and clear TGH/TGH glazing. It’s made a huge difference to the space - the room feels noticeably brighter and the slim frame gives it a really clean, modern finish from both inside and out.

Build quality feels solid and well-made, and once fitted it looks properly “architectural” rather than bulky. The glazing looks great and the overall unit feels premium. Installation onto a prepared upstand was straightforward for our installer and it’s been completely weathertight.

Also worth mentioning: the pricing/discount on my order was excellent value for what you get. Really happy overall and I’d recommend it to anyone upgrading a kitchen extension or flat roof area.
