An innovative rigid air barrier to provide defence against wind and moisture in external facades
A 6mm specialised fibre cement rigid air barrier that can be used beneath cladding, providing added protection against the elements. This 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. Easy to install and can be exposed for up to 180 days before installing the cladding.
