saveBOARD betterBRACE Rigid Air Barrier is a cost-effective rigid air barrier for use in residential to multi-story construction. Designed for use in Extra High wind zone. Finished with an external moisture resistant Fiberglass facing material; it is an alternative to traditional building underlays.
It allows builders the ability to close in a building sooner to begin interior fit out, along with additional noise and insulation properties. The fit out can be started independently of the exterior rain screen minimising potential delays to the project.
Reduce the carbon footprint of new or refurbished buildings by using betterBRACE rigid air barrier with a Total Global Warming Potential (A1-A3) -5.5 kg CO2e/m2 (or -550kg CO2e/m3).
