Sisalation® Vapawrap™ Vapour Permeable Metal Roof

• Technical Data Sheet Sisalation® Vapawrap™ Metal Roof  Intended for use in Australia’s cold regions where a water-proof, vapour permeable membrane is required.
• Sisalation® Vapawrap™ Metal Roof is synthetic roof sarking specifically designed for use under a range of roof cladding materials.
• BRANZ Appraised.
• When used in a metal roof application, Sisalation^® Vapawrap™ Metal Roof shall be installed as a continuous membrane to allow for drainage of liquid water into the gutter.
• Features a micro-porous water resistant film sandwiched between two layers of mould and shrink resistant, spun-bonded polyolefin.
• Provides greater heat shrink resistance compared to traditional polymer-weave based membranes, and is therefore less likely to shrink in a metal roof application.
• Helps to mitigate the risk of condensation.
