IBS RigidRAP: The Next-Generation Rigid Air Barrier for Faster, Stronger, Weather-Tight Builds

When designing homes for New Zealand’s variable climate, architects need solutions that deliver durability, speed, and compliance. IBS RigidRAP is a rigid air barrier that doubles as a bracing element, reducing complexity and saving time on site.

Why choose RigidRAP?

  • Dual functionality: Acts as both a rigid air barrier and structural bracing, minimising the need for additional bracing inside.
  • Weather protection: Laminated underlay keeps walls dry and secure for up to 90 days of exposure, even before cladding is installed.
  • Energy efficiency: Reduces air leakage, improving thermal performance and indoor comfort.
  • Compliance: Fully CodeMark certified, meeting NZ Building Code requirements for external moisture (E2/AS1).
  • Design flexibility: Available in multiple lengths for timber-framed projects.

A recent residential development in Canterbury faced tight deadlines and unpredictable weather. The design team selected IBS RigidRAP for its ability to provide immediate weather protection and structural bracing. Installation was straightforward, and interior work continued without delay.

“RigidRAP gave us confidence to keep moving despite the rain. It simplified compliance and saved us time,” said the project manager.

Ideal applications:

  • External wall wrap — rigid air barrier
  • Internal/external wall bracing
  • Temporary weather cladding

Manufactured from sustainably sourced OSB, RigidRAP supports environmentally responsible building practices.
