Achieve Acoustic Performance of STC64 with INTEGRA Central Barrier Intertenancy System

There is nothing worse for new homeowners in medium density apartments than to discover they can hear more than they expected from their new neighbours. The intent with acoustics is to prevent or significantly reduce airborne or impact sound travelling between tenancies so the dwelling owners can enjoy their space.

Equally, architects, designers and engineers require surety that the products they specify are tested, robust solutions that will exceed building code requirements.

When Resene Construction Systems designed their INTEGRA Central Barrier Intertenancy Walling System, they worked with innovative acoustic and fire engineers to create a system that firstly needed to exceed the Building Code requirements in terms of acoustics and fire performance, and also a system that was simple, fast and efficient to install.

INTEGRA ticked all the boxes — the standard system provides an acoustic performance of STC64 with a single layer of 10mm plasterboard — this is nine points higher than the NZBC STC55 requirement. The system also achieved a 2hr fire rating (FRR120/120/120) with the same standard specification.

INTEGRA Central Barrier Intertenancy Wall systems have been through full scale testing including BRANZ Fire lab, and Auckland University Acoustics lab with all test results available on the Resene Construction website. There are no secrets or systems based on opinion when it comes to such an important investment.

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.
