Window Energy Ratings - WER Documentation

With carbon emissions high on the global agenda and the current high cost of fuel, consumers are looking for ways to make their homes more energy efficient. When you get a product rated with the BFRC you will be given a unique label. Window Energy Ratings use a consumer-friendly traffic-light style A-E ratings guide similar to that used on household goods such as fridges, freezers and washing machines.

his ratings label can be used by consumers to make more informed choices about the energy efficiency of the windows they are looking to purchase. Euroglaze offer a WER Documentation System to our Trade Accounts as an added value service which automates the Window Energy Rating System.

This label will display the following information:

  • The rating level A, B, C, D, E, F & G
  • The energy rating e.g. 4kWh/(m²·y) in this example the product will lose 4 kilowatt hours per square metre per year
  • The window U value e.g. 1.5W/(m²·K)
  • The effective heat loss due to air penetration as L e.g. 0.02 W/(m²·K)
  • The solar heat gain e.g. g=0.41
