RAB board, the rigid air barrier by James Hardie, was designed to meet the building industry’s changing requirements for high-performance weather barriers. This green panel is sealed with James Hardie’s innovative Coreshield penetrating sealer technology, keeping water, air and wind out while allowing moisture vapour to easily escape and enabling the framing cavity to drain and dry.
Installed beneath external cladding or rainscreens, RAB board delivers water resistance, long-term durability and strength and is also suitable for use in non-combustible construction. The result of James Hardie’s extensive innovation and research into durable and resilient facade design, RAB board provides a fully certified solution that offers superior defence against wind and moisture.
Improved weatherproofing for the life of the building results from the RAB board solution, which creates a continuous weatherproof seal across the building. James Hardie’s durable Coreshield penetrating sealer technology provides a barrier that stops moisture getting in, while RAB board’s advanced breathable design allows vapours to escape.
- Allows buildings to stand up to 7 kPa high wind pressures
- Suitable for non-combustible construction
- Quick and easy to install
