Shining Daylight On Rooflight EPDs

A dome rooflight

Rooflight supplier Brett Martin Daylight Systems has achieved environmental product declarations for two of its site assembled and one of its factory assembled rooflights.

In order to support customers with environmental product declarations (EPDs) for its most popular products, Brett Martin approached the Building Research Establishment.

For configurations not covered by the EPDs, Brett Martin says it is able to generate a configuration specific assessment. This also means that the embodied carbon of Brett Martin’s industrial rooflight systems is available for specifiers and building owners to respond to enquiries from the market.


 “As we head to a low carbon future the importance of transparent and independently verified environmental data is increasingly valued.”

"For a company committed to supplying sustainable products and one which constantly invests to make its products and manufacturing processes more sustainable and efficient, this is a great advance,” continues Brett Martin's Hawker.


UK made

All of Brett Martins’ products are designed, developed and manufactured in the UK in its own ISO 9001 quality accredited and ISO 14001 environmentally accredited factories. With BBA certification and CE marking throughout the range, Brett Martin has built up a reputation for providing a rooflight product that is backed by full technical support.



Brett Martin claims to be the UK’s only manufacturer producing GRP, PVC and Polycarbonate sheets, and its extensive range of pitched and flat roof daylighting products, including glass, are used by roofing contractors in diverse projects in every sector.
