The foil is bonded to a reinforcing polymer mesh treated blue to cut glare. Each roll is 1350 mm x 60 m, covering 81 m².\u003c\/p\u003e\n\u003ch3\u003eWind and added R-value\u003c\/h3\u003e\n\u003cp\u003eThor call it a heavier product, better suited to walls in high wind locations. By their figures it can add up to R1.1 to a wall behind brick veneer or timber cladding and up to R1.3 to a roof insulation system. Reaching those figures takes at least 20 mm of air space next to the foil face.\u003c\/p\u003e\n\u003ch3\u003eClimate zone limits on walls\u003c\/h3\u003e\n\u003cp\u003eUnder NCC 2022, a membrane outside the insulation in a house or apartment wall needs at least 0.143 µg\/N.s in climate zones 4 and 5, and 1.140 µg\/N.s in zones 6 to 8. This one is a vapour barrier at 0.011 µg\/N.s, so as a wall wrap it meets the deemed-to-satisfy rule in zones 1 to 3 only. Melbourne is zone 6.
