Our saveBOARD betterBRACE 4Steel product is a thermally broken rigid air barrier. A cost-effective, high-performance exterior sheathing for steel-framed buildings, suitable for everything from residential homes to multi-storey construction. Engineered for strength, it is designed for use in Extra High wind zones and finished with a moisture-resistant facing material for superior durability, combined with a 10mm EPS backing to provide an R 0.4 thermal break.
betterBRACE allows builders to close in a building faster, enabling interior fit-outs to begin sooner - even before the exterior rain screen is installed. This not only reduces potential project delays but also provides additional noise reduction and insulation benefits.
By choosing saveBOARD betterBRACE, you contribute to carbon-negative construction. With a Total Global Warming Potential (A1-A3) -3.8 kg CO2e/m2 (or -550kg CO2e/m3), it takes carbon out of both new builds and refurbishments.
