Aluminium foil is bonded to a reinforcing polymer mesh treated blue to cut glare. Thor's selection guide places it in brick veneer walls.\u003c\/p\u003e\n\u003ch3\u003eNot a water barrier\u003c\/h3\u003e\n\u003cp\u003eThor class this perforated wrap as a Non-Water Barrier, so it relies on a drained cavity, which brick veneer has by design. Their condensation guide rules out lightweight cladding in any situation, even with a battened cavity, because perforated non-water barrier products do not meet cladding manufacturers' warranty terms.\u003c\/p\u003e\n\u003ch3\u003eCheck the climate zone first\u003c\/h3\u003e\n\u003cp\u003eFor houses and apartments, NCC 2022 wants a membrane outside the wall insulation to reach 0.143 µg\/N·s in climate zones 4 and 5, and 1.140 µg\/N·s in zones 6, 7 and 8. Class 3 is the minimum for zones 4 and 5. It falls short in zones 6 to 8, Melbourne included, where a Class 4 wrap is the deemed-to-satisfy choice.
