It is medium duty, with a Class 2 Vapour Barrier rating and a Water Barrier classification. Thor list it for BAL 12.5 to FZ. One roll is 1350 mm x 60 m and covers 81 m².\u003c\/p\u003e\n\u003ch3\u003eA vapour barrier, so check the climate zone\u003c\/h3\u003e\n\u003cp\u003eThor describe Primo as non-permeable (0.106 µg\/N.s) and recommend it for warmer climates, since a vapour barrier on the cold side of a wall can trap condensation. Under NCC 2022 a house wall wrap must reach 0.143 µg\/N.s in climate zones 4 and 5 and 1.140 µg\/N.s in zones 6 to 8. Primo meets that deemed-to-satisfy rule only in zones 1 to 3, which excludes house walls in Melbourne and Sydney. Use a vapour permeable wrap there, such as \u003ca href=\"\/products\/sisalation-vapawrap\"\u003eSisalation Vapawrap\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eWhat the foil adds\u003c\/h3\u003e\n\u003cp\u003eBehind brick veneer or other cladding with a drained cavity, Thor state up to R1.1 may be added to the wall. For a brick cavity wall with a 90 mm stud and 40 mm cavity, they declare RT 1.2 summer and RT 1.3 winter. Leave at least 20 mm of air space next to the foil face to get there.\u003c\/p\u003e\n\u003ch3\u003eOn site\u003c\/h3\u003e\n\u003cp\u003eInstall to AS\/NZS 4200.2, seal the overlaps and clad promptly, as the wrap is not made for long weather exposure.
