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.Cross References:BS EN 932-1:1997BS EN 13055:2016BS 3882:2015PAS 100
