RAB Board pre-cladding by James Hardie

James Hardie has released a new product designed to meet the building industry’s changing requirements for high-performance weather barriers: RAB Board. 

A rigid air barrier that is installed beneath external cladding or ventilated facades, RAB Board is made from James Hardie’s premium fibre cement and sealed with the company’s Core Shield penetrating sealer technology, keeping water, air and wind out. The unique green pre-cladding panel delivers superior water resistance, long-term durability and strength, and is also suitable for use in non-combustible construction.
