KOROK® Fire and Acoustic Wall Systems at Catalina Bay Apartments
KOROK Building Systems played a key role in the construction of the Catalina Bay Apartments in Auckland, supplying our high-performance fire and acoustic wall systems. This 13-level waterfront development, built by LT McGuinness for client Willis Bond, consists of 73 luxury apartments across two towers and nine townhouses on a concrete podium. Designed by Architectus, the project integrates sustainability, history, and high-end living, offering panoramic views of Waitemata Harbour.
The Catalina Bay Apartments were built on a historically significant site, once home to a Royal New Zealand Air Force base. The design of the development pays homage to this heritage while providing modern, high-quality residences.
Despite construction challenges such as extreme weather events and pandemic-related delays, the project was successfully completed in July 2024, thanks to the collaborative efforts of the client, consultants, and contractors. More than 2,200 workers contributed to this impressive 28-month build.
KOROK® – Setting the Standard in Fire and Acoustic Protection
KOROK is proud to have contributed to this landmark residential development, providing solutions that ensure safety, comfort, and efficiency. Our fire and acoustic wall systems continue to set the benchmark for high-performance construction in New Zealand’s premium apartment projects.
KOROK supplied all fire and acoustic wall systems for the project, including:
Lift Shafts, Risers, and Ducts
Intertenancy Apartment Walls
Our systems were chosen to enhance fire safety, acoustic insulation, and construction efficiency in this high-end residential development.
KOROK® for Lift Shafts, Risers, and Ducts
KOROK® panels provided an efficient and robust solution for the lift shafts, risers, and ducts at Catalina Bay, offering multiple advantages:
Single-side installation: Eliminates the need for scaffolding inside shafts, accelerating the build process.
Pre-weather installation: Our panels can be installed before the building is fully enclosed, preventing water ingress through open shafts and risers.
Superior fire and acoustic performance: Ensuring compliance with New Zealand’s strict building codes for safety and comfort.
KOROK® for Intertenancy Apartment Walls
Each apartment in Catalina Bay was designed for privacy and luxury. KOROK® intertenancy walls played a crucial role in achieving this by delivering:
Proven fire-rated protection and acoustic insulation, ensuring a safe and peaceful living environment.
Solid wall construction, enhancing security and long-term durability.
Faster installation times, reducing project timelines and labor costs.
Sustainable solutions, minimizing construction waste and contributing to the development’s Homestar-7 sustainability rating.
KOROK Systems used in this project
Lift Shafts, Risers, Ducts
For lift shafts and duct walls, KOROK® offers significant advantages over traditional construction. As panels can be installed from one side only, there is no requirement to construct scaffolding inside the shaft, greatly reducing construction time and costs.
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.
