BRE Green Guide Generic Ratings

The BRE Green Guide lists environmental ratings for various types of flat roof construction and the waterproofing system utilised. Ratings are from E (worst) to A+ (best)

Listed below are examples of ratings that our systems can generically achieve when installed on different deck types and support structure used within a specification.  These may also have different ratings depending on the building type.
