betterBRACE - Rigid Air Barrier
(7mm & 10mm)
CodeMark Certified
10mm betterBRACE
New Zealand Made

The saveBOARD betterBRACE Rigid Air Barrier is a cost-effective, high-performance rigid air barrier that goes up in place of traditional building underlays, suitable for everything from residential homes to multi-storey 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 carbon-negative 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 takes carbon out of both new builds and refurbishments, not just less than plasterboard-based systems would add.

  • Engineered composite board for external underlay applications.

  • Excellent Impact resistant

  • Excellent wind & seismic bracing capacity

  • Noise attenuation with high STC rating - 30dBA at 10mm thickness board only

  • ZERO Water, Glues, Chemicals added. VOC's and Formaldehydes are < 5% of the Green Building Standard (0.005mg/m2/hr) 

  • Declare label: Our products have been determined to meet the requirements for all applicable Imperatives of the Living Building Challenge.

  • Use MasterSpec 4171SB​

  • Bracing Capacity:

    • 10mm

      • Bracing unit 0.4m x 2.4m; W = 65 BU/m EQ = 76 BU/m​ 

      • Bracing unit 0.6m x 2.4m; W = 87 BU/m EQ = 98 BU/m​

      • Bracing unit 1.2m x 2.4; W = 143 BU/m EQ = 154 BU/m​

    • 7mm

      • Bracing unit 0.4m x 2.4m; W = 44 BU/m EQ = 48 BU/m​ 

      • Bracing unit 0.6m x 2.4m; W = 65 BU/m EQ = 69 BU/m​

      • Bracing unit 1.2m x 2.4; W = 104 BU/m EQ = 110 BU/m​

Note: This installation video is for our 10mm betterBRACE rigid air barrier, noting the nail fixing spacing is different for the 7mm betterBRACE product.

Option A – Synthetic Wrap
