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.

KOROK® is simple to install. You can get an installer group to do it for you – there are several installer groups around the country – or, if you’d like to install it yourself, we are very happy to offer free on-site training (subject to location). For more information on either option please contact us on 0800 773 777 or at info@korok.com.
We also have comprehensive installation guides for each and every KOROK® wall system. You can print these below, or contact us if you’d like us to send you hard copies.
KOROK® wall systems can be installed either vertically or horizontally, with clear steps to ensure a secure and high-performance outcome. Key steps include sealing the C-track with fire-rated sealant, precise cutting of panels, and correct placement using a tilt-and-snap action to lock panels together. Panels are fixed with screws at specified centres, and sealant is applied to maintain fire and acoustic integrity. Detailed guidance is provided for handling the last panels and ensuring proper finishing.
For full installation details, refer to the comprehensive guides below or contact us for support.
These animations are for illustrative purposes only. Please refer to the appropriate KOROK Systems Manual for complete and current installation instructions.
Designing cantilevered terraced houses is simplified with KOROK® fire and acoustic wall systems. Whether you need cantilevered eaves or cantilevered walls, KOROK has detailed solutions to suit your needs.
Our systems help you create functional and stylish designs, such as:
Maximizing floor space with larger second-story extensions.
KOROK’s innovative cantilevered wall systems are engineered to provide superior performance, offering both structural stability and efficient installation for terraced house construction. Choose KOROK® to streamline your building process and meet the demands of modern architectural design.
For Terraced Housing
Cantilevered terraced house design is easy with KOROK®. We have details for both cantilevered eaves and cantilevered walls. So if you’re wanting your buyers to be sheltered from the weather with an inset front door; or if you’re wanting to maximise your floor space with a larger second storey, we have the product to make that happen.
Cantilevered Eaves
Cantilevered Walls
For External Applications – (Commercial Only)
A Typical Parapet Detail illustrates the structure and support of a parapet wall, commonly cantilevered from the main building structure. This detail focuses on connections that ensure stability and durability, including reinforcement and weatherproofing layers to protect against the elements. Cantilevered parapets require careful attention to load distribution and deflection control, as they extend outward without external bracing, creating a clean, streamlined edge on the building façade.
