IBS RigidRAP and RigidRAP-XT: Rigid Air Barriers Manufactured by Kiwis for Kiwis

With the uncertainty and shipment delays of the global supply market, nationwide shortages are gradually rising. Building projects in New Zealand are going through massive delays, pushing builders and architects to look for alternatives in order to be able to complete their projects.

For the past 30 years, IBS (Independent Building Supplies) has been sourcing and providing products for kiwis to build better homes. The 100% New Zealand owned company understands the building industry's increasing demand for locally manufactured products.

IBS RigidRAP and RigidRAP-XT are the only dual-layer and tri-layer rigid air barrier systems available on the New Zealand market and are also manufactured locally. These 8mm and 18mm OSB3 boards are engineered in Germany and then laminated with a BRANZ-appraised building paper here in New Zealand.

Lightweight, easy to cut, nail or screw, RigidRAP and RigidRAP-XT can speed up the building process by up to nine weeks for a standard three-bedroom home. The products can be exposed to the weather for up to 90 days and replace traditional building paper wrap. The boards can also be used as temporary weather cladding as well as providing structural bracing.

IBS understands that having supplies readily available is crucial for architects and builders to deliver projects on time and budget. In order to guarantee supply timeframes, IBS is getting RigidRAP and RigidRAP-XT boards manufactured every day to respond to the increasing demand. IBS is also able to reduce delivery delays by having months' worth of materials for manufacture secured and with more coming in the country every month.

As kiwis move towards more sustainable, durable and local products, RigidRAP and RigidRAP-XT are filling the need for a readily available rigid air barrier system in New Zealand.

RigidRAP and RigidRAP-XT are available in 2440 x 1196mm, 2745 x 1196mm and 3050 x 1196mm sheets and can be used with a multitude of approved tapes. These well-liked products are CodeMark certified and have a suite of product documents including the PASS and have even become standard building features for some builders and architects.

IBS RigidRAP and RigidRAP-XT are stocked by several merchant stores but can also be ordered in directly via your local merchant. IBS is currently able to complete orders and deliver in less than 10 business days.

IBS RigidRAP and RigidRAP-XT — responding to the building industry's demand for sustainable, local and readily available products.
