Flat Roof Domes

A great option for flat roofs is a domed rooflight, which helps to increase the natural light into the room below. Flat roofs can suit a range of different shaped rooflights, but domed tend to be good for smaller spaces which might not be able to accommodate a larger flat rooflight. The domed shape allows more light to enter the space, along with offering a practical and durable finish.

Domes can be used on a large range of building styles and can offer additional benefits such as UV protection and ventilation, depending on the specifications used.

Will a dome rooflight discolour over time?

Modern domed rooflights are manufactured from hardwearing polycarbonate and all have a UV protective coating to stop them discolouring in the sun. Previously dome skylights were commonly made from acrylic which would turn brown after years exposure to sunlight often leaving the rooflight looking unsightly. Polycarbonate domes are guaranteed against discolouration for 20 years however they are expected to exceed this so you can feel safe in the knowledge that your rooflight will look exceptional for years to come. For the UV coating to be effective the dome or pyramid must not be scratched or harmed in any way which may damage the UV coating.
What is a dome roof light?

Dome rooflights are an inexpensive way to bring light into your home or commercial building. Made from durable non-fragile polycarbonate which has an impact strength up to 250 times greater than glass. Available as a top only to retrofit to an existing upstand or complete with a PVC kerb for fitting directly to the roof. We have a vast array of stock sizes available with different ventilation options along with bespoke polycarbonate rooflights available on request.
What is a U Value?

U Values are how heat loss is measured through roofs. A U Value is shown in units of W/m²K and the lower the number the better the thermal performance of the rooflight is. As a general rule rooflight for new domestic applications need to have a U value no higher than 1.8W/m²K.
