James Hardie Rigid Air Barrier (RAB) 6.0mm 2750x1200 - each

RAB™ Board is an all in one bracing, airtight and fire resistant fibre cement rigid air barrier. The inherent strength of RAB Board makes it an ideal product for use in shear wall design in residential or commercial specific design projects.

RAB Board is a non-combustible material which will achieve excellent fire performance, unlike traditional flexible and timber wall underlays. The unique green panel has a built in air and water resistant barrier to keep moisture out, while still allowing the moisture vapour to pass through allowing framing cavity to dry.

RAB Board has up to 60 minutes fire resistance rating and superior acoustic performance to reduce external noise. It can be exposed for up to 180 days without warping or shrinking.
