Transform your home with a stunning Orangery Lantern Roof Light

Natural light is one of the most desirable qualities a home can have and installing a glass lantern roof is a more affordable and quicker alternative to a full glass extension or conservatory installation and pose fewer building regulations and planning permission issues.

Bathe your home in natural light, and add the illusion of added space...

Available in a wide range of shapes and sizes, a roof lantern will improve the look of the outside of your house and have no clunky bars or profiles cluttering the ridge or dominating the glazing. Our super strong, light, 40mm aluminium box rafters create slim, elegant roof profiles with excellent thermal performance. Compared to conventional roofs, our roof lanterns reduce the visible width and sightlines of rafters by 30% and the main feature ridge by 70%.

This unique design creates a feeling of MORE SKY – LESS ROOF giving you visible elegance to your roof design and appearance, whether you choose an all Aluminium structure or want PVCu capping – less is definitely more.
Using the benefits of slimline technology we have combined good looks, outstanding thermal performance and intelligent detailing, to create one of the finest looking lantern roofs available.
