Firefighters Build a Stronger Station with IBS RigidRAP

IBS RigidRAP is the only dual-layer Rigid Air Barrier system available in New Zealand. It is an 8mm OSB3 product that has been laminated with an approved building paper to give builds dual protection from the weather during the building process.

RigidRAP is not only a temporary weather cladding but it also provides structural bracing. The product is lightweight, easy to cut, nail or screw, and can be exposed to the weather for up to 90 days. IBS RigidRAP replaces traditional building paper wrap to above all support a healthier, stronger building.

Used by the Cook Brothers in Christchurch, the Ilam Fire Station is reaping the benefits of a faster, stronger build by enclosing the build and protecting it from the elements allowing interior work to begin.

IBS RigidRAP comes in three different sizes, 2440, 2745 and 3050mm all by 1196mm, allowing for rapid install. Several flashing tapes have been tested on RigidRAP allow for a choice of tapes to be used on projects.

IBS RigidRAP is tested to the highest standard New Zealand offers, CodeMark Certification. Builders can rest easy knowing that CodeMark is an unchallengeable form of product assurance (building.govt.nz, 2016).

The Cook Brothers have enjoyed using RigidRAP and look forward to using it on their next project.
