NZBC-Compliant Passive Fire Protection for KOROK® Wall Systems
When it comes to passive fire penetrations, KOROK® leads the way with innovative solutions that ensure fire safety without compromising functionality.
At KOROK®, we are committed to providing fire-rated wall systems that prioritize safety, durability, and performance. Our advanced KOROK® panels are specifically designed to allow seamless integration of passive fire penetrations, including service ducting and pipes, while maintaining the structural and fire integrity of the wall.
What Are Passive Fire Penetrations?
Passive fire penetrations are openings or pathways in fire-rated walls or floors that allow services such as plumbing, electrical cables, or ductwork to pass through. These penetrations are essential for building functionality but must be carefully designed to prevent the spread of fire and smoke. KOROK® panels are engineered to make the creation and sealing of these penetrations straightforward and effective, ensuring compliance with strict fire safety standards.
At KOROK®, we understand that ensuring fire safety goes beyond the wall system itself – it’s also about how penetrations and services are detailed. That’s why we’ve collaborated with leading experts in passive fire protection to develop a suite of manuals that provide fully tested, NZBC-compliant solutions for penetrations in KOROK® fire-rated wall systems.
Each manual has been developed in partnership with industry specialists and contains tested configurations, installation guidance, and compliance references, making it easier for designers, engineers, and contractors to select the right firestop solutions.
Our firestop manuals, developed with industry partners, provide tested and NZBC-compliant solutions for service penetrations in KOROK® fire-rated wall systems.
Easy Formations for Penetrations: KOROK® panels simplify the creation of openings for ducting and plumbing. The lightweight yet robust design makes it easy to form precise and efficient penetrations without compromising fire safety or wall integrity.
Maintained Wall Integrity: Even with multiple passive fire penetrations, KOROK® panels ensure the overall wall system retains its fire rating. This is crucial for preventing fire and smoke from spreading across compartments in a building.
Versatile Applications: Whether your project involves commercial spaces, residential apartments, or industrial facilities, KOROK® passive fire penetrations provide a reliable and efficient solution tailored to meet your needs.
Compliance with Building Codes: KOROK® panels are rigorously tested and meet or exceed New Zealand’s building code requirements for passive fire protection. This gives architects, engineers, and builders confidence in the safety and performance of their projects.

Engineered Fire and Acoustic Systems for Industrial and Commercial Spaces
KOROK® Warehouse and Retail Systems are high-performance, non-loadbearing internal wall systems designed to provide secure fire separation and acoustic control in industrial, warehouse, bulk retail, and intertenancy environments.
The system consists of interlocking steel-faced panels with an aerated concrete core, engineered for certified fire resistance, acoustic attenuation, structural reliability, and long-term durability. Panels can be installed vertically or horizontally and are suitable for both single-wall and twin-wall configurations. The systems have been developed in accordance with recognised Australian and New Zealand Standards and are substantiated through BRANZ testing and appraisal(Appraisal No. 559), ensuring verified and compliant performance.
How the System Works
KOROK® panels are roll-formed from zinc-coated steel strips and encapsulate a lightweight aerated concrete core. The interlocking tongue-and-groove profile forms a continuous sealed barrier that enhances both fire integrity and acoustic isolation.
System performance is achieved through the combined effect of panel mass and composite action, the engineered interlocking joint design, and a tested fastening and support methodology. Optional linings and cavity configurations can also be incorporated to meet specific Fire Resistance Rating (FRR) and Sound Transmission Class (STC) requirements.
Systems are non-loadbearing and must be supported by primary structural elements designed in accordance with NZBC structural requirements. Only genuine, tested KOROK® panels and proprietary components guarantee certified system performance. Substituting alternative products may compromise fire and acoustic ratings and cannot be supported or certified.
