Let the natural light to flood in

Letting natural light into your home can be a challenge especially when extending your property.

Often a set of multi-folding doors or a large area of glazing can be specified to help achieve this, however a glazed section within the roof is an obvious way of letting the light flood in.

Modern lanterns with large glazed panels and small sections can suit any contemporary project, whilst a traditional look can be achieved with smaller rafter spacings and a steeper pitch. Modern Lantern Roof systems constructed on flat roofs offer a very effective solution and can be designed to specified to meet your architectural needs. 

Our lantern roof systems incorporate glazing with the latest technological glazing that ensure you have the best available when it comes to thermal efficiency with all the added benefits of self-cleaning and solar control.
