Everything you need to know about changes to the Australian National Construction Code.
In Australian climate zones 6, 7 and 8, a vapour permeable membrane must be used on the external wall, providing an air and water barrier, which assists insulation performance, while still allowing water vapour to escape, reducing the risk of condensation.
A detailed map of the affected zones and regions are included our NCC brochure.
Vapour permeable membranes consist of a micro-porous layer of breathable film to hold out water (water barrier) while allowing water vapour to escape (vapour permeable). They provide an air and water barrier, which assists insulation performance, while still allowing water vapour to escape, reducing the risk of condensation.
Synthetic Permeable Roof & Wall Membranes
A home with synthetic permeable membrane installed on its roof and walls will provide a controlled escape path for the water vapour to flow from the cavities. The diagram above shows the movement of heat, air and water vapour through the building structure.
