RAB® Board

Pre Cladding that creates better performing homes and buildings.

RAB^™ Board is an all in one bracing, airtight and fire resistant fibre cement rigid air barrier. An ideal product for use in residential or commercial specific design projects.

RAB Board is a non-combustible material which achieves 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 the 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.

RAB Board is suitable for the exterior of residential and commercial buildings including those in Extra High (EH) wind zones. It is fixed directly to the framing and then vertical joints are sealed over the face. Suitable for use behind all James Hardie claddings or claddings such as brick, timber weatherboard and more.
