We have been manufacturing rooflights since 1954, and in that time we have gained valuable experience in the manufacture and distribution of specialist flat roofing daylight and ventilation systems throughout the UK.

Everything we manufacture at COXDOME is quality tested to the very highest standards. With professional accreditations and ISO9001 – 2008, all aspects of our manufacturing and operational process is stringently audited to ensure our processes maintain consistency and our production continually meets the requirements of our customers.

At COXDOME we understand the importance of natural daylight. Daylight brings us new energy, it brings the world to life at home, outdoors and at work. It has been scientifically proven that daylight makes people feel better and perform better.

COXDOME uses innovative, sustainable daylight solutions to help capture the most of this inexhaustible supply. For over 60 years we have provided a wide-ranging assortment of daylight solutions, in both plastic and glass, that take our client’s inspired ideas and turn them into practical applications.
