This British Standard specifies requirements for the testing of substrates (the growing medium) forconstructed green roofs intended to provide long term support for specified plant communities. Thisincludes extensive and intensive green roof substrates.
This British Standard provides methodologies for testing green roof substrates covering the completeapplication range, and recommended specifications for physical and chemical characteristicsconsidered to be optimal for extensive substrates.
This British Standard only addresses methods and parameters to ensure that the substrate used doesnot become a limiting factor for successful green roof installation. It does not address the wider rangeof other design considerations, such as the supporting structure, construction, planting options orpost-build maintenance.
It is recognized that there are green roof systems that do not incorporate a substrate layer and theseare not covered in this British Standard.
