Sound Solutions for Loud Workspaces: How KOROK Panels Tame Machinery Noise
When machinery is operating at high intensity, the noise can be just as intense as the output. Whether it’s recycling, manufacturing, or any high-impact industrial process, managing sound is not just a comfort issue – it’s a health, safety, and productivity one.
At KOROK, we understand the challenges that come with acoustic performances. That’s why our fire and acoustic wall systems are engineered to offer more than just compliance – they’re built to perform under pressure, especially when sound control is critical.
The challenge? Containing the loud crashes and clinks from their glass recycling facility – an essential part of their operation, but not the easiest on the ears.
Our solution was simple but effective: construct a purpose-built enclosure using KOROK fire and acoustic panels – essentially a “box” that wrapped around the recycling machinery to absorb and block the sound.
The result? Immediate improvement.
“The box looks awesome and works well,” the Xtreme team told us. It’s now a noticeably quieter and more comfortable environment for staff and visitors alike.
Why KOROK Panels Work for Noisy Machinery
KOROK wall systems are purpose-built for industrial environments, offering high acoustic performance to reduce machinery noise, along with fire resistance for added safety. Their durable construction ensures reliable performance under pressure, while the modular design allows for tailored solutions—from full enclosures to partitions. Plus, they deliver a clean, professional look, as demonstrated in real-world applications like Raglan.
For facilities like Xtreme Zero Waste, acoustic control isn’t just a luxury – it’s essential to keep workers safe, comply with council noise regulations, and maintain good relationships with surrounding communities. So, if you’re facing excessive noise from machinery, get in touch. We’ll help you design a system that keeps the sound where it belongs – inside the box.

KOROK Panels at Work in Raglan: Quieting the Glass Recycling Hub
We’ve just wrapped up a project at the Xtreme Zero Waste recycling center in Raglan, where we installed a “box” using our fire and acoustic panels around their glass recycling facility. The goal? To keep the noise down from the glass recycling process. The crew at Xtreme Zero Waste couldn’t be happier, saying, “The box looks awesome and works well.” It’s great to see our panels doing their job, making the space quieter and more comfortable for everyone involved. We’re stoked to have been part of this project and to see our panels making a difference right here in Raglan.
In factories, warehouses and bulk retail environments, KOROK® provides strong, solid separation walls that are secure and fire compliant with high noise insulating properties.
Costco Auckland, Standing Strong with KOROK® Wall Systems
Costco, the world’s second-largest retailer, opened its first New Zealand store in October 2022 at 2 Gunton Drive, Westgate, Auckland. Part of the expansive Westgate Shopping Centre, this new 15,000m² retail space features overhead parking for over 800 vehicles and includes essential services like a fuel station, tyre centre, food court, optometrist, and hearing aid services. This store is a key addition to the rapidly growing Northwest Auckland community, built on a challenging site during the COVID-19 pandemic. As a solid structure made of steel and concrete, Costco Auckland stands as a durable retail hub that incorporates the high-performance KOROK® wall system.
KOROK® supplied 78mm fire-rated acoustic panels (GEN 2) for several key areas of the Costco Auckland project, delivering fast installation and exceptional quality. Our system provided pre-finished internal walls, ensuring a sleek and clean aesthetic, combined with robust fire safety and acoustic insulation.
Key Areas Where KOROK® Panels Were Used:
Separation Walls: Between the entry and main shop (7.2m high, ColorSteel Titania finish)
Lift Surrounds: ColorSteel Titania panels installed around the main lifts
Fire Escape Stairwells: Galvanized panels left visible for fire compliance
Why KOROK® for Warehouses and Retail?
KOROK® wall systems are designed for large-scale environments like warehouses and bulk retail stores. Our strong, secure separation walls offer:
Superior Fire Resistance: Compliant with all fire safety regulations
Noise Insulation: High acoustic performance for noise control in busy environments
Fast Installation: Single-panel system simplifies and speeds up construction
Aesthetic Quality: Pre-finished panels provide a clean, professional look
Costco Auckland’s successful construction is a testament to KOROK®’s ability to meet the needs of high-demand retail spaces. Our fire-rated acoustic panels delivered both safety and efficiency, ensuring a sturdy, high-performing structure that aligns with Costco’s global standards.

Warehouse, Retail, Factory
In factories, warehouses and bulk retail environments, KOROK® provides strong, solid separation walls that are secure and fire compliant with high noise insulating properties.
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.
High-Performing and Lightweight Panels for Superior Building Solutions
The 78mm KOROK® panels are engineered to provide exceptional performance in both fire and acoustic applications. These panels are roll-formed from high-quality COLORSTEEL® steel strips, with the steel conforming to the rigorous AS/NZS1397:2001 standard.
The combination of steel shells and an aerated concrete core ensures outstanding durability and functionality. Weighing approximately 10.2kg per lineal metre, these panels offer a lightweight solution that does not compromise on strength or safety.
Applications of 78mm KOROK® Colour Panels
Our 78mm KOROK® colour panels are versatile and suitable for various building applications, including:
KOROK® External Wall Systems: Ensuring robust protection with excellent thermal, acoustic, and fire-rated properties.
Lightweight Construction: Simplifies installation and reduces structural load requirements.
Durability: Engineered to withstand demanding conditions.
Efficiency: Panels are pre-finished and easy to install, reducing construction time and costs.
