Energy Efficient Windows and Doors

WER Energy Window Label DuraflexWindow Energy Ratings (WER) provide information about the energy efficiency and thermal performance of windows. Thermal performance ratings are calculated by our in-house approved simulator and verified by the BFRC; the ratings scale goes from A++ to E, with ‘A++’ being the most efficient, and ‘E’ the least. The latest Building Regulations require all new homes to have windows with a minimum ‘C’ WER rating.

During the rating process the energy efficiency level is calculated and verified by BFRC, which is totally independent from any manufacturing or installing company. Manufacturers of BFRC rated product and BFRC Authorised Installers are audited to ensure that their energy efficient windows are achieving the stated rating. The BFRC energy ratings allow you to compare varying window products and choose the most suitable for your application.
