Lantern roofs are thermally efficient, create a prominent feature in your home and complement our entire suite of aluminium windows, bifolding doors, and sliding doors.

The latest trend in glazed roofs, different from traditional conservatories. Perfect for an existing flat roof as well as your new extension. We use the prestigious Roof Maker range of advanced lantern roof products.


Technology & Design

Every one of our lantern roofs comes made to order to to your sizes, colour and other requirements. The technology behind our cutting edge aluminium roof focuses on strength, weather resistance and long term performance. The lantern roof design makes it suitable for converting an existing flat roof too.

The aluminium profiles come with thermal insulation offering clean contemporary sightlines and perfect as standalone roofs or as part of a new orangery. The lantern roofs design takes inspiration from high rise facade glazing with slim roof bars and only the essential structural components. As a result, you get a minimalist design with no unsightly support bars or tie rods. All visible aluminium components come with a durable powder coated finish that is easy to keep clean and comes with at least 15 years guarantee on the paint finish.

Thermal efficiency is excellent thanks to highly insulated glass units available in either double or triple glazing.

Standard rooflights come with fixed panels but you can also choose opening manual or automatic vents for improved ventilation. The electric versions also come with a combined heat and rain sensor option too.

Product Features


Clean joints, a modern look and designed for maximum structural integrity. The components and hardware used in our lantern roofs take advantage of the slimline aluminium frames and create one of the slimmest roofs available. Your home benefits from a neater looking design, more light and excellent structural integrity.

Designed to suit any size hole in a flat roof, our rooflights use advanced thermal insulation between the aluminium profiles, helping to prevent the build-up of condensation. Other components include optional traditional or contemporary finials and crestings or a minimalist look without any top decoration. The intelligent design means the opening is easy to create, the lantern simple to fit with most installations simply needing the roof to lift onto the upstand.

Your project goes smoother thanks to an easier aperture for your builder to create and the lift on design, making this roof easy to set on a timber kerb.


Double or triple glazed units are high quality in construction for maximum clarity and light transmission. The glass units come with warm edge spacer bars, low-E coatings and argon gas fill. We also make cleaning easy and with minimal effort, thanks to the easy-clean glass coatings provided as standard with most products.

Also available are enhanced glass options such as sun-cool, solar control, and other options for enhanced security or comfort or to meet your budget.


The professionally applied marine-grade powder coating to your new lantern roofs ensures this always exposed roof product keeps its looks for years. Your roof, therefore, withstands harsh weather conditions with only routine cleaning of the aluminium profiles recommended to keep your roof looking new.

White, grey and black remain our most popular colours, but we also offer hundreds of other combinations from the RAL colour range.

The powder-coated surface on your new lantern roof protects the aluminium, resists corrosion and offers excellent low-maintenance properties.

Energy Efficiency

Double and triple glazed options available, achieving Ug-values as low as 0.8w/m2K with high specification glass, yet still energy efficient with more standard glass units.

Importantly, the glass we use is what contributes substantially to the excellent thermal performance. With 80% of the energy lost through a window being at the glass unit edge, we use the best Edgetech spacer bars making the glass in your new lantern roof substantially better than metal spacer bars.

As a result, you get a more comfortable room, lower heating bills and a stunning glass lantern roof in your home to enjoy.
