At Cleartherm, we pride ourselves on quality – we won’t settle for any less than the best, and we believe that our customers shouldn’t have to either.

Over the last three years, we have invested over two and a half million pounds in cutting edge technology to keep pace with today's changing needs. 

The new technology allows us to produce double or triple glazed units to help you achieve the energy rated windows and doors that the industry demands. 

Our products can help reduce your carbon footprint, as well as save money, by offering an energy efficient solution. For more information on any of our range, just visit the relevant product page below
