Calculator tool

For this scheme of BREEAM there is no Mat 04 calculator tool, the evidence required to demonstrate compliance with issue Mat 04 ‘Insulation’, is the same as that outlined in Mat 03 ‘Responsible sourcing of materials‘, such as copies of the relevant responsible sourcing scheme certificates, corresponding invoices etc. To demonstrate compliance the design plan/specification must report the insulation materials’ specifications, area, thickness, the total percentage volume of insulation that is responsibly sourced and their associated Tier levels.
