Achieve Next Level Fire and Acoustic Performance with INTEGRA

Our goal with fire and acoustic separation is not just to meet the NZBC requirements, it is to exceed them with one standard specification, in a cost-effective manner to minimise construction costs without compromising performance.

Resene Construction Systems have a solution that addresses these issues with their New Zealand designed and engineered INTEGRA Central Barrier Intertenancy System. This proprietary high-performance wall system provides tested systems for resistance to horizontal fire, as well as acoustic separation between adjacent tenancies in the same building with either timber or steel framing.

The solution is straightforward, practical and reliable. The system has a minimum fire rating of two hours (FRR 120/120/120 - BRANZ tested), and a minimum STC acoustic rating of 64 (Auckland University Acoustics Lab) with a single layer of standard 10mm plasterboard. This acoustic rating can be increased to STC 67 with 13mm plasterboard interior lining. This well exceeds the minimum building code requirements for buildings of this kind, which is STC 55.

The core components of the INTEGRA Central Barrier Intertenancy System are the 50mm thick INTEGRA AAC concrete panels and acoustic isolation brackets. The INTEGRA panels and acoustic isolation brackets are installed once the first side of the framing is stood up. Then once the adjacent tenancy line of framing is stood up the acoustic separation brackets are fixed in place. The framing then has insulation and plasterboard lining fixed and ready for finishes.

Resene Construction Systems INTEGRA Intertenancy Systems has been carefully designed to New Zealand conditions and independently tested and assessed to ensure it meets the performance criteria as outlined in NZBC:

B1 — Structure: The design and specification for timber framing must be in accordance with the performance requirements of NZBC B1. Framing used in accordance with NZS3604:2011 is compliant in accordance with NZBC B1 and is the best choice to use when using a Resene Construction Systems Intertenancy System. Where the framing falls outside the requirements of NZS3604:2011 it is recommend that an engineer is engaged to ensure that structural compliance is met.
B2 — Durability: Under normal conditions of internal use, the Resene Construction Systems Intertenancy System will achieve a service life in excess of 50 years and satisfy the requirements of NZBC B2.
C1-C6 — Protection from Fire: The Resene Construction Systems Intertenancy System can be used to provide passive fire protection in accordance with the requirement of NZBC C1-C6 – Protection from Fire. The Resene Construction Systems Intertenancy System has been peer reviewed and meets the provisions of NZBC C1-C6 when kept within the scope as outlined in Section 5 Scope of use for the Resene Construction Systems Intertenancy System.
F2 — Hazardous Building Materials: Under normal conditions of internal use, the Resene Construction Systems Intertenancy System does not constitute a health hazard and meets the provisions of the NZBC Clause F2.
G6 — Airborne and Impact Sound: The Resene Construction Systems Intertenancy System provides airborne noise control ratings that exceed the minimum requirements of NZBC Clause G6 — Airborne and Impact Sound. The Resene Construction Systems Intertenancy System has been peer reviewed and meets the provisions of NZBC G6 when kept within the scope 5 Scope of use for the Resene Construction Systems Intertenancy System.
