Description

KOROK® has set a new benchmark in seismic performance, demonstrating exceptional durability under rigorous in-plane and out-of-plane seismic testing. KOROK Panels have the ability to withstand high levels of drift , ensuring minimal damage, reduced repair costs, and faster recovery after earthquakes.

BRANZ Seismic Test:

Key Features

Leading the Market in Seismic Testing — KOROK® has recently undergone comprehensive seismic testing, setting a new benchmark to support our fire and acoustic wall performance. For over 25 years, KOROK have delivered high-performance solutions across the residential, industrial, and commercial markets.
The Purpose Behind Testing — To understand and determine the behaviour and performance of KOROK wall panels when subjected to seismic design loads occurring between structural slabs within buildings.
To demonstrate how KOROK® panels respond in correlation with drift levels for both in-plane and out-of-plane conditions, and to support the market with tested solutions. By undertaking this seismic testing, KOROK® reinforces its commitment to superior building resilience, helping to minimise damage, lower repair costs, and maintain operational continuity after earthquakes.
Importance of Seismic Resilience — The 2010/2011 Christchurch earthquakes and the more recent 2013 Lower North Island earthquakes illustrated the vulnerability of building non-structural elements (partitions, building services and piping). Widespread damage and loss of business continuity due to the poor performance of non-structural elements was widely observed
The Canterbury Earthquakes Royal Commission identified the need to improve the performance of non-structural elements in earthquakes with one of the recommendations focussed on improving non-structural element performance. “To prevent or limit the amount of secondary damage, engineers and architects should collaborate to minimise the potential distortion applied to non-structural elements. Particular attention must be paid to prevent the failure of non-structural elements blocking egress routes.”
Proven Seismic Performance — Conducted at BRANZ in 2024, KOROK's seismic tests followed FEMA 461 and NZS 1170.5:2004 standards, confirming KOROK® panels has the ability to withstand high levels of drift. No other system in New Zealand has undergone such rigorous testing with multiple wall configurations and variations.

Scope of Use

Application in High-Importance Structures:

As the ultimate All-in-One solution for fire & acoustic-rated wall systems, KOROK® panels offer unmatched performance for high-importance structures.
With strong seismic performance and the ability to withstand high drift limits, KOROK® panels are ideal for IL3 and IL4 buildings, such as hospitals, emergency response centres, and essential utilities.
KOROK® provides stakeholders, architects, and engineers with confidence in a durable, high-performance solutions.

Statement of Building Code Compliance

The NZBC sets out both the legal minimum sound transmission between tenancies (Clause G6) and minimum levels of fire resistance (Clauses C3 and C6). The KOROK Intertenancy Systems Manual provides guidance on the specification and construction of systems that will both meet and exceed those minimum levels. However, designers should consider the comfort of occupants when selecting a system that will satisfy the occupants' expectations when using the space rather than the minimum required by law.

NZBC:

Clause B1: Structure — The KOROK Systems meet the requirements for loads arising from self-weight, earthquake, wind, impact and creep and shrinkage
Clause B2: Durability — Under normal conditions of dry internal use KOROK Intertenancy Systems have a serviceable life in excess of 50 years and satisfy the requirements of NZBC Clause B2 Durability
Clauses C3: Fire Affecting Areas Beyond the Source — KOROK Intertenancy Systems can be used to provide passive fire protection in accordance with the requirements of NZBC Clause 3: Spread of Fire
Clause C6: Structural Stability —Compliance with (NZBC) Clause C6 'Structural Stability'. In order to satisfy the requirements of the New Zealand Building Code (clause 6) relating to Structural Stability designers must ensure that KOROK elements are supported by primary elements that have at least the same fire rating as the KOROK system that is used
Where the primary elements supporting the KOROK system are outside the fire cell, there is no requirement to apply the same FRR as the KOROK system. Notwithstanding, post fire stability requirements of the NZBC must also be satisfied
Clause G6: Airborne and Impact Sound — KOROK Intertenancy Systems, both meet and exceed the minimum requirements outlined in NZBC Clause G6. Consideration should be given to both the minimum requirements and the comfort of occupants
