How Do Double Glazing U-Values Affect Window Energy Ratings (WERs)?

Double glazing U-values play a crucial role in Window Energy Ratings (WERs), which assess overall window efficiency. The British Fenestration Rating Council (BFRC) regulates WERs, and windows with lower U-values typically receive higher ratings. Glasscraft ensures its products meet high WER standards, providing customers with energy-efficient glazing that contributes to a greener home.
