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.

Real-World Results in Raglan: Xtreme Zero Waste

A great example of this in action is our recent project at the Xtreme Zero Waste Recycling Center in Raglan.

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® Seismic Test

KOROK Sets a New Benchmark in Seismic Performance

KOROK® has raised the standard for seismic resilience, proving its durability in the toughest conditions. Recent seismic testing conducted at BRANZ in 2024 confirmed that KOROK panels can withstand high levels of drift, ensuring minimal damage, reduced repair costs, and faster recovery following earthquakes.

These rigorous tests, performed in accordance with FEMA 461 and NZS 1170.5:2004 standards, evaluated KOROK panels under both in-plane and out-of-plane seismic conditions. No other system in New Zealand has undergone such extensive testing across multiple wall configurations.

With their exceptional seismic, fire, and acoustic performance, KOROK panels are the ideal choice for high-importance structures, including hospitals, emergency response centres, and essential utilities. This milestone reaffirms KOROK’s commitment to delivering market-leading solutions that enhance building resilience and safety.

KOROK’s Sustainability Journey

At KOROK, sustainability is a core value. Our journey towards carbon neutrality is marked by significant milestones that reflect our commitment to reducing our environmental impact and enhancing the eco-friendliness of our products.

2001 Launch into New Zealand Market.

Between 2001 and 2017:

KOROK, initially launched in New Zealand as SPEEDWALL, focused on improving construction with streamlined systems that reduced waste, minimised lining needs, and boosted efficiency. Our commitment to sustainability has been integral since the start.

• Manufacturing Efficiency: Upgraded technologies to reduce energy use and optimise resources.
• Wastewater Management: A modern treatment plant for recycling and reducing water impact.
• By-product Reduction: Enhanced recycling processes to minimise waste.

2017: DECLARE Label

In 2017, we obtained the DECLARE Label, listing the ingredients in our products and aligning with the LEED green building rating system. This helped us meet industry standards and be included in GreenStar and HomeStar ratings.

April 2021: Joining NZ Green Building Council

In April 2021, we joined the New Zealand Green Building Council (NZGBC), supporting eco-friendly building practices.

December 2021: Environmental Choice New Zealand Licence

By December 2021, we obtained the Environmental Choice New Zealand Licence, recognising our products as better for the environment, enhancing our credibility among architects and builders and helping us gain accreditation for GreenStar and HomeStar products.

March 2023: Carbon Footprint Analysis

In March 2023, we conducted a carbon footprint analysis of our panels, meeting market demands and preparing for new NZ Building Code regulations.

April 2023: VOC Emissions Analysis

We analysed VOC emissions from our sealants in April 2023, addressing health concerns and meeting the demands of architects.

July 2024: Environmental Product Declaration (EPD)

In July 2024, we completed our Galv Panel Environmental Product Declaration (EPD), followed by our Colour Panel EPD in August, providing a verified summary of our product’s environmental impact over their life cycle. These EPDs are recognised internationally and often specified in tender documents and contracts.

Ongoing Carbon Reduction Efforts

Our commitment to sustainability includes ongoing initiatives to reduce our carbon footprint:

• Upgrading lighting to LEDs.
• Converting forklifts from LPG to battery power
• Recycling steel scrap.
• Recycling office and kitchen waste.
• Repurposing leftover concrete for clean fill.
• Exploring options to reuse leftover concrete and alternative fibres.
• Continuously reviewing and reducing printing.
• Factory looking at swapping from cheap throwaway pneumatic punches to something more robust (May 24)
• Even though an EPD is valid for 5 years, we will constantly review ours. We are looking forward to the changes that NZ Steel have planned for next year, moving from BOF furnaces (primary) to EAF furnaces (secondary). This will have a very positive impact on our Carbon footprint.

KOROK’s sustainability efforts highlight our commitment to reducing our environmental footprint. From the DECLARE Label to our EPDs, we continuously strive for improvement, aiming for a greener, more sustainable future.

Environmental Product Declarations (EPDs)

We are proud to announce the completion of our Environmental Product Declarations (EPDs), a testament to our commitment to transparency and sustainability. One for our Galv panel and one for our Colour panel.

What is an EPD?

An Environmental Product Declaration (EPD) is a certified, independently verified summary of a product’s environmental impact over its entire life cycle. It evaluates:

• The materials extracted from the earth.
• Energy used in the production, transportation and installation.
• The environmental impacts of using, disposing, or recycling the product.

The EPD covers a range of environmental indicators, including the potential for carbon emissions, air and water pollution, and depletion of natural resources. Based on international standards (ISO 14025 and EN 15804 for building materials), our EPD is independently verified, making it a trusted and reputable source of information. It is recognized by industries, companies, and governments, and is often specified in tender documents and contracts.
