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.
How many layers does my dome rooflight need to be?

Polycarbonate rooflight domes are available in four different thicknesses. Single skin domes are only suitable for using in areas such as a shed outhouse or garage and are useful for letting in light where thermal properties are not important. Double skin domes can be used when retrofitting a dome to an existing kerb they are better thermally than single skin domes but may still experience condensation. For new builds triple skin dome rooflights are used to comply with pat L of the current building regulations. Quad skin dome rooflights offer the highest thermal efficiency and may be an option if heat-loss is a particular concern.
