This medium density board is highly vapour ‘breathable’, transporting excess water vapour outward – keeping structures dry and healthy.

For use as an external cladding board for timber frame or solid masonry and cavity wall retrofit projects or as an internal acoustic board.

Fixing of the boards is simple: thermally broken fasteners are installed through the insulation boards to the supporting structure. The board can either be rendered onto or lie behind battens and an air gap for any type of cladding – timber, metal, ceramic or brick.

Occupants will benefit from a complete thermal envelope to reduce thermal bridging through framework and a healthy, moisture-regulating fabric.
