RAB™ Board
A 6mm specialised fibre cement rigid air barrier that can be used beneath cladding, providing added protection against the elements. James Hardie’s durable CoreShield™ penetrating sealer technology provides a barrier that helps prevent moisture getting in, while RAB™ Board’s advanced breathable design allows vapour to escape.
RAB™ Board’s can be used in applications which require a solution which can stand up to 7kPa high wind pressures. Because RAB™ Board is made from fibre cement, unlike with some wraps, high wind pressures won’t cause tears or openings, which is especially important in taller buildings or in cyclonic regions.
RAB™ Board is lightweight, easy to cut with a Villaboard™ Score and Snap Knife, and screw or nail to the frame, while the joints are simply taped. Classified as a Class 4 Vapour Permeable Membrane, RAB™ Board is suitable for use in Australian Climate Zones 2 to 8 in accordance with the National Construction Code (NCC) 2022.
Key Features
- Easy to install
- Fire resistant
- Resistant to moisture damage and termite damage
- Can be exposed for up to 180 days before installing the cladding
- 25-year product warranty
