Green Guide ratings are now available for our range of BBA-approved roofing systems when featured in a flat roof design. The Green Guide Ratings form the basis of construction material ratings for BREEAM and The Code for Sustainable Homes assessments.

Liquid applied waterproofing systems, such as those manufactured by Polyroof, achieve up to an A+ rating when used in a warm roof construction, which is the highest possible rating for a flat roof design.
The ratings are available on the BRE Green Guide to Specification website, where the correlating generic ratings for Polyroof’s systems appear in the guide as follows:

The Green Guide ratings enhance Polyroof’s continual commitment to the environment, which includes:

  • ISO14001 Environmental Management System accreditation.
  • Manufacturing all of our products in the UK using locally sourced products where possible. This dramatically cuts down on the amount of carbon involved in the production and distribution of our products.
  • Superior durability ratings to ensure optimum flat roof life-cycle costings are achieved
