Window Energy Ratings (WER)
Window Energy Ratings are a guide to the energy performance of your windows. The British Fenestration Ratings Council, also known as the BFRC, ensures all the components of your windows meets the required energy rating standards. A window can achieve a rating from A-G depending on how efficient it is. The more efficient the window, the higher the energy rating – A being the most thermally efficient.
The minimum requirement for new homes is a ‘C’ WER rating so this is a useful benchmark to use when considering replacement windows. The good news is, our uPVC windows have an energy rating of beyond A+ thanks to their superior multi-chambered profile and uPVC thermal inserts. Our window frames are one of the most energy efficient profiles in the UK.
Sustainable and Environmentally Friendly
All our uPVC windows are manufactured using sustainable methods. We use 100% recycled materials in our thermal inserts and all our components meets the standards of ISO14001 of environmental performance.
