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.

51mm KOROK® panels are rollformed from zinc coated steel strips. The steel from which the shells are manufactured conforms to AS/NZS1397:2001. Steel shells have a base metal thickness of 0.4mm B.M.T. with a Z275 zinc coating. These panels have an aerated concrete core and weigh nominally 10.2kg per lineal metre.
KOROK® produces 51mm panel. KOROK® 51mm panel provides a -/60/60 FRR and is perfectly suited for terraced house intertenancy walls and apartment intertenancy walls. The narrower gauge allows you to keep more floor space as it isn’t taken up by walls.
Performance and Features
Fire Rating: KOROK® 51mm panels provide a fire resistance rating of -/60/60 FRR, meeting stringent safety requirements for intertenancy walls in terraced houses and apartments.
Acoustic Efficiency: Designed to reduce sound transmission, these panels ensure quieter living environments, making them an excellent choice for densely populated or high-traffic areas.
Space-Saving Design: The 51mm thickness allows for slimmer walls, helping to maximize valuable floor space without compromising structural integrity or performance.
Applications and Systems
Vertical Orientation: Panels are installed vertically and secured to timber or steel framing with aluminum brackets.
Versatility: Compatible with wall framing, insulation, and linings specified within the system appraisal, ensuring seamless integration into your building project.
Scope of Use: Appraised for all buildings of all importance levels as defined by AS/NZS 1170.
