BRE Green Guide Ratings

Wood Window Alliance windows are now recognized as a separate standard in BRE’s Green Guide to Specification:

  • All WWA timber windows are rated A+ 
  • All WWA aluminium-clad timber windows with a clear internal finish are rated A+ 
  • WWA aluminium-clad timber windows with an opaque internal finish are rated A

These ratings are the best available in each category and provide specifiers with the confidence that they are choosing windows and doors that will help them meet BREEAM, Code for Sustainable Homes, or other sustainability standards.
