Description

IBS RigidRAP®-XT is a rigid air barrier and bracing element and provides temporary protection from the weather during construction.

It contributes thermal resistance to the wall and incorporates a thermal break for use with light steel framing. It is suitable for use on new and existing steel framed or timber framed buildings founded on either a concrete floor slab or timber subfloor. When all joints are sealed with a flashing tape, no flexible wall underlay is required.

IBS RigidRAP®-XT is an 8mm OSB panel product faced with a laminated synthetic building wrap and with 10mm lightweight rigid foam on the rear of the panel.
