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.
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.
Why Choose KOROK® for Passive Fire Penetrations?
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.

Hobsonville Point: Enhancing Fire and Acoustic Protection with KOROK® Intertenancy Systems
Bringing Kiwi Ingenuity to Hobsonville Point Homes
Here at KOROK®, we’re stoked to have been part of the transformation of the old Hobsonville airbase into a new community. Our innovative KOROK KIR Intertenancy Residential Walls have been key in shaping around 3000 homes across this significant slice of land, including standout spots like the Te Uru Apartments, Walter Merton Road Terraces, Nugget Avenue Terraces, and Buckley A Precinct.
Being part of the Hobsonville Point development really showcases our ability for coming up with smart solutions that tackle the real-world challenges of modern building, especially when it comes to keeping fires at bay and cutting down on noise. Traditional wall setups in flats and hotels usually lean on linings to do this job. But our KIR walls change the game by ditching the need for these linings up top, making the whole building process simpler and slicker.
Smoother Sailing in Building and Design
Our walls have made it quicker and easier to get buildings up at Hobsonville Point. That’s good news for the teams on the ground and means residents can start enjoying their new digs sooner.
Keeping Costs Down
Thanks to the technology behind our KIR panels, we’ve cut down on waste, which means saving some dollars. Those savings can help make other parts of the development even better, making the whole neighbourhood a top spot to live.
Top-Notch Fire and Sound Safety
We’ve put our walls through the wringer to make sure they’re up to scratch for fire safety and noise control. That means folks living in Hobsonville Point can sleep easy, knowing they’ve got solid protection around them.
Built Solid for Extra Peace of Mind
The sturdy design of our walls means homes are not just safe but also built to last. That’s a big plus for anyone calling Hobsonville Point home, offering a secure spot for years to come.
Committed to Excellence in Innovation and Community Building
From the lively look of the Te Uru Apartments to the tidy and thoughtful design of the Walter Merton Road Terraces and the spot-on style of Buckley A Precinct, our KIR panels have been a foundation for success, delivering the goods on fire safety and quiet living. As we look back on our role at Hobsonville Point, we’re chuffed to have delivered solutions that not only tick the boxes for what’s needed in today’s building scene but also help forge strong, safe, and green communities. Our dedication to coming up with better ways to do things will keep us at the forefront of making homes better for Kiwis everywhere.
KOROK Systems used in this project
Intertenancy Terraced Housing
In terraced housing and town houses, conventional framed wall systems rely on the internal linings for fire-resistance. Penetrating these linings potentially destroys the fire-rated barrier.
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:
Weather protection with inset front doors for enhanced shelter.
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
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.
KOROK® 78mm galv 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.
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.
