Pre-Cladding & Rigid Air Barriers

Pre-Cladding

Leading the way

For over 19 years James Hardie has created an evolution for the way New Zealanders build, we were the first to design and manufacture a specific product for use as a rigid air barrier called RAB^™ Board, which now sets the benchmark for pre-cladding. Made from Hardie™ fibre cement board they meet the challenges of an evolving world, creating a stronger building and comfort inside any living space. James Hardie create innovative, high performing and sustainable products that allow your wall underlay to meet the durability requirements and live up to their full potential.

How does it work?

Rigid air barriers by James Hardie work by equalising the air pressure within the external wall cavity, making the building airtight providing superior weather-tightness, structural bracing and fire protection, whereas traditional flexible wall underlay can struggle to perform in these conditions.
