Specification for performance parameters and test methods for green roof substrates Ingestion-build-141043 refillable containers intended only forWhat is this standard about? A green roof is typically understood to be an intentionally vegetated roof or platform disconnected from the underlying ground. Substrate is a key component of any green roof and directly contributes to its success. The suitability of a green roof substrate can be assessed by measuring key performance parameters. This British Standard specifies requirements for the testing of substrates (the growing medium) for constructed
