WER (Window Energy Ratings)

Window Energy Ratings (WER) were established by the British Fenestration Council (BFRC) in 2004, with the aim of easily comparing the energy-efficiency of windows. The energy rating is dependent on how much energy the window will either lose or supply the property of they year. In consequence, the window will be given a rating for A (best) to G (worst), in order to easily show the energy-efficiency of the product.
