What is RigidRAP?
RigidRAP is a rigid air barrier system designed to replace traditional building wrap during construction. It provides a stronger pre-cladding layer that helps manage moisture, support weathertightness, and create a more durable wall build-up.
Replaces traditional building wrap
A rigid system that helps provide better support and protection during the build.
Supports moisture management
Designed to help reduce water infiltration and support a healthier wall system.
Creates a stronger substrate
Provides a solid surface for flashing tape at openings and penetrations.
Choose the right system for your build.
Both systems are designed to replace traditional building wrap with a rigid air barrier, but they suit different build requirements.
RigidRAP
A dual-layer rigid air barrier system designed to support moisture protection, bracing, and a stronger build process.
Best for:
Timber frame builds
External wall bracing
Temporary weather cladding
Faster build sequencing
RigidRAP-XT
A triple-layer rigid air barrier system with an added graphite polystyrene thermal break, making it especially well suited to steel frame builds while also suitable for timber frames.
Best for:
Steel frame builds
Thermal break applications
Temporary weather cladding
Faster build sequencing
Why Builders Choose RigidRAP.
Speeds up building time
A strong rigid structure helps streamline the build process on site.
Quick moisture protection
Provides earlier protection for the building as construction progresses.
Supports uninterrupted interior work
Helps keep internal work moving while the exterior envelope is still being completed.
Creates a stronger substrate
Helps reduce some of the movement issues associated with exposed structural timber.
Improves on-site security
A more robust external layer than traditional wrap alone.
Adds structural support
Designed to contribute to a stronger and more weather-resistant wall system.

Commonly asked questions about RigidRAP.
RigidRAP is a dual-layer rigid air barrier system, while RigidRAP-XT uses a triple-layer design with an added graphite polystyrene thermal break. RigidRAP-XT is especially well suited to steel frame builds, while both systems are designed to support moisture protection and weathertightness.
RigidRAP is designed to replace traditional building wrap with a rigid air barrier system that provides a stronger pre-cladding layer during construction.
Yes. RigidRAP-XT is well suited to steel frame builds because of its thermal break layer, and it can also be used on timber frame buildings.
RigidRAP can be left exposed for up to 90 days.
Yes. All vertical and horizontal joins need to be taped.
Yes. A 2mm gap should be left around the perimeter of all sheets.
Yes. RigidRAP systems can be used as a bracing element when installed in line with the required fixing system and installation details.
Yes. The system is designed to support moisture protection and weathertightness as part of the wall build-up, helping reduce water infiltration during construction and over the life of the building.
