betterbrace (7mm & 10mm)

The saveBOARD betterBRACE Rigid Air Barrier is a cost-effective, high-performance alternative to traditional building underlays, suitable for everything from residential homes to multi-story construction. Engineered for strength, it is designed for use in Extra High wind zones. It is available in two thicknesses:

7mm for direct substitution and good bracing capacity (up to 110 BU/m)
10mm for superior bracing capacity where you need maximum performance (up to 154 BU/m)

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 sustainable construction. With a Total Global Warming Potential (A1-A3) – 3.8 kgCO2e/m2 for 7mm & -5.5 kgCO2e/m2 for 10mm (or -550kg CO2e/m3), it actively reduces the carbon footprint of both new builds and refurbishments.
