Non-combustible E-glass fabric bonded to 97% reflective aluminium foil, perforated so water vapour can pass through. 1350 mm x 30 m covering 40.5 m².\u003c\/p\u003e\n\u003ch3\u003eNon-combustible and permeable at the same time\u003c\/h3\u003e\n\u003cp\u003eMost vapour permeable membranes are polymer based, and polymer burns. This one is not deemed combustible to AS 1530.1, with early fire hazard indices of 0, 0, 0 and 2, and it complies with the NCC Deemed-to-Satisfy provisions for non-combustible construction. It is also rated for use in all BAL zones under AS 3959. If a commercial facade or a Flame Zone job needs both a breather membrane and non-combustible material, this is the product that does both.\u003c\/p\u003e\n\u003ch3\u003eBarrier vs breather\u003c\/h3\u003e\n\u003cp\u003eClass 3 vapour permeable at 0.8698 µg\/N·s.
