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.
KOROK® has recently undergone comprehensive seismic testing, setting a new benchmark to support our fire and acoustic wall performance. For over 25 years, we have delivered high-performance solutions across the residential, industrial, and commercial markets.
To understand and determine the behavior 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 minimize damage, lower repair costs, and maintain operational continuity after earthquakes.
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.”
Conducted at BRANZ in 2024, our 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.
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.
