Product Description

IBS RigidRAP®-XT is an 8mm OSB3 (Oriented Strand Board) which has been manufactured specifically for New Zealand, for use as a bracing element and/ or rigid air barrier. IBS RigidRAP®-XT is the only triple layer rigid air barrier system available in New Zealand and comes laminated with a watertight wall underlay.

RigidRAP®-XT is not only a temporary weather cladding, but it also provides bracing. IBS RigidRAP®-XT has a 10mm lightweight rigid foam fixed to the rear of the board. This gives IBS RigidRAP®-XT a R-Value of 0.39.
It replaces the traditional building wrap, and when compared to similar products it is more cost effective, easy to install and is lightweight.

As an OSB3 panel manufactured in accordance with EN13986:2004, it is suitable for use in humid conditions where the panel in-service moisture content does not exceed 20%.

Compliance with the NZ Building Code (NZBC) is established through Product Certification (CodeMark). Compliance with NASH standard Part Two: ‘Light Steel Framed Buildings’ (or NZS 3404:2009 - Steel Structures) IBS RigidRAP®-XT meets all the requirements of Table 23 of E2/AS1 from the compliance document for the NZ Building Code (NZBC).
