Australian made, it is a thermal break, insulation and vapour barrier for steel-framed walls and metal roofs over battens.\u003c\/p\u003e\n\u003ch3\u003eWhy 90 and not 70\u003c\/h3\u003e\n\u003cp\u003eKingspan state that Insulbreak 70 and 90 deliver the R0.20 thermal break required for NCC compliance in steel-framed buildings. On a steel-framed wall under metal cladding, 90 is declared at RT 1.4 for heat flow in and out, against RT 1.3 for the 7.2 mm Insulbreak 70. That wall result is the only system figure published for 90.\u003c\/p\u003e\n\u003ch3\u003eVapour barrier, so check the wall design\u003c\/h3\u003e\n\u003cp\u003eIt is a Class 2 vapour barrier and is not suitable as a vapour permeable membrane in NCC climate zones 4 to 8, which take in Melbourne and Sydney.

On walls, fix it loosely outside the studs, tape butt joins with 48 mm reinforced foil tape and add AIR-CELL Spacer Biscuits, about three per m², to hold an air space behind the cladding. Keep it 100 mm clear of flues and light fittings, and away from bare cables.
