What is its Purpose and Who is it for?
Fundamental to this guidance is the principal that a Blue Roof should not be considered as a water storage solution.
No British or European standard covers this type of application at this moment in time. Which is why a committee formed of the NFRC Joint Flat Roofing Technical Committee, whose members include, Membrane and System Manufacturers, Insulation Producers, Standards and Certification Bodies, Drainage Consultants and representatives from Flat Roofing trade associations, was tasked to produce the guidance to support the design of technically correct Blue Roof construction and provide information for specifiers, designers and installers.
