Maximise natural light intake with an aluminium roof lantern

Aluminium roof lanterns are a great way to bring an abundance of natural light into a building interior. Thermally broken aluminium frames are used to boost energy efficiency while the structural strength of the aluminium allows for larger glazed areas.

All fixings on our aluminium lantern roofs are hidden inside the frame. This creates an attractive aesthetic appearance both inside and outside. The spas and ridge sections are only 57mm wide. These are some of the slimmest available today, ensuring that natural light intake is not unnecessarily impeded.

Aluminium lantern roofs features and benefits

Super-slim sightlines

Aluminium’s inherent strength allows for the slimmest frames capable of supporting large glass panes. This creates more glass equaling more natural light intake for a brighter interior.

Excellent thermal efficiency

With U-values as low as 1.2 – 1.4 W/m²K, our lantern roofs can significantly improve a building’s energy efficiency. Designed to boost thermal performance, they will help to keep warm air in and cold air out.

10-year guarantee

All our aluminium lantern roofs come with a comprehensive 10-year guarantee. In the unlikely event that you experience a problem, you can relax, knowing that you’re covered for the next decade.

Quick delivery

We can deliver bespoke aluminium lantern roofs to any address in the UK (excluding Edinburgh) within four weeks of order placement.

High-quality aluminium

Our aluminium lantern roofs are made using only the highest quality aluminium profiles. Strong, durable, and easily customisable, our aluminum lantern roofs are an excellent choice.

Affordable prices

At Prime Aluminium, we offer some of the UK’s most competitive prices on aluminium lantern roofs. Our aluminium lantern roofs are a premium product at an affordable price.

Aluminium lantern roofs colour customisation

At Prime Aluminium, our aluminium lantern roofs are available in three standard colours. Choose from Gloss White, Matt Grey, or Matt Black. These three standard colours can be specified in any combination for the interior and exterior of the frames. For complete customisation, you can also specify your aluminium lantern roof in any of over 160 RAL colours.

Aluminium lantern roofs performance specifications

All our aluminium lantern roofs are 100% made to measure and designed to meet your exact specifications. Their maximum size is 6000mm x 4000mm with a maximum weight of 8000kg. They have a frame depth of 69mmwith internally beaded 28mm double glazing. With typical sightlines of 57mm, they’ll bring a wealth of natural light into any interior.

To help maximise thermal performance, our aluminium lantern roofs feature an innovative insulating T-bar. This bridges the gap between the profiles and the aluminium finishing caps to create the largest thermal break possible. When combined with high performance glazing and a thermally broken eaves beam, your room interior will remain at an ambient temperature all year round.

Frequently Asked Questions

Is aluminium a better option?
Yes. Aluminium is stronger, more durable, more customisable, and more environmentally friendly than alternative material such as uPVC.
Can I have any size roof lantern?
The maximum size for our roof lanterns is 6m x 4m. Any bespoke size is available up to this maximum.
How easy are roof lanterns to install?
Roof lanterns are relatively easy to install for any experienced glazier. For homeowners, we recommend using a registered window fitter.
Do I need planning permission to install a roof lantern?
Most roof lanterns do not require planning permission. However, a roof lantern must not extend more than 150mm above the existing roof. It can also be no higher than the highest part of the existing roof and no openings are allowed unless the roof lantern is at least 1.7 metres from ground level.


Wonderful service from start to finish. I came across Prime Aluminium online, after receiving a few quotes from others I found these to be the best price I could find. Delivered within the time scale promised and really pleased with the quality of the doors. Send them a picture of your door after it’s been fitted and you will be entered in to a draw for a voucher. Fingers crossed. Thank you.

Very happy with our doors, we got a few quotes from some other companies which was in excess of £10,000 for 4 bi-folds – Prime Aluminium saved us over £3000. Anyone thinking about fitting yourself just make sure there is 2 of you as the panels are about 50kg each. Will recommend in the future to anyone looking for new bifold doors.
