As housing becomes more intensified and terraced housing and apartments more prevalent in New Zealand, enhancing their products to meet the more complex needs of the compact homes more Kiwis are living in is something GIB® is continually looking to improve.

GIB® Intertenancy Barrier Systems for Terraced Homes provide an NZBC-compliant separating wall between attached dwellings, delivering fire protection, noise control and bracing qualities.

Winstone Wallboards has worked with designers, builders, and developers to bring new enhancements to this product range, making it easier to install alongside more versatile options designed to help streamline the building and consenting process.

GIB® Intertenancy Barrier System, a system designed for connected dwellings to meet fire resistance and noise reduction ratings, now offers more versatility and easier installation.

New construction details

Winstone Wallboards has added new construction details, including options addressing a cantilevered mid-floor area, stepped roofing profiles, and a timber base level detail.

New 30-minute fire resistance rating option for roof space laminate

Reviewing the roof space laminate options has allowed GIB® to offer an alternative of the lighter, 10mm GIB Weatherline® for systems where 30-minute fire resistance ratings are required.

Option of a 13mm GIB Fyreline® or GIB Weatherline® layer to support longer exposure time

Cost saving through improved systems by replacing the 16mm GIB Fyreline® with 13mm GIB Fyreline® and adding the offer of using a layer of 13mm GIB Weatherline®, which offers a longer exposure time to align with the current offer of 90 days weather exposure of the GIB Barrierline® system.

Two new steel frame options with a 60-minute fire-resistant rating

There are now two new steel frame systems (GBSLAB 60a and GBLSAB 60b) with 60-minute fire resistance ratings available and an STC of 61 and 67, respectively.

Putting it all together, GIB® is here to help

Detailed illustrations of each new option are included in the GIB® Intertenancy Barrier System literature. In addition, we have added QR codes, which take you directly to a step-by-step animated assembly process.
