Technical Bulletin July 2024

KOROK has a culture of investing in product testing across our core market segments, believing in developing systems that simplify construction with robust, evidence-based performance.

As our market evolves, so does the demand for high-performance, compliant systems. KOROK continually strives to stay ahead, providing evidence-based solutions, supporting documentation, technical support, and literature to the New Zealand Construction Industry.

Our technical team, led by David Cornelius, brings a wealth of experience and a deep passion for the KOROK brand. We balance product innovation, testing, and technical support, ensuring that the industry benefits from practical, test-based solutions.

Pathway to testing:

KOROK collaborates with leading institutions such as BRANZ,  Auckland University Acoustics Testing Services, CSIRO, and Warringtonfire Australia, alongside industry-leading fire and structural engineers, manufacturers, and consultants. This collaboration aims to deliver performance-based solutions that meet ever-evolving design requirements.

The testing process begins by identifying industry challenges, followed by setting objectives and the steps required to facilitate a solution. KOROK evaluates both suitability and compliance requirements while considering simple installation methodologies. A systematic evaluation of needs leads to a well-structured test program and assessments.

David and his team rigorously assess and refine processes, aiming to provide the market with simple, high-performance systems and applications that enhance both functionality and efficiency. Our goal is to ensure that every product meets the highest standards of performance and reliability.

Sustainability

At KOROK, we aim to balance industry and nature. We’re committed to providing high-performance products with a minimised environmental impact.

Our Commitment to Waste Reduction

At KOROK, we focus on reducing waste and being environmentally responsible. Our efficient manufacturing processes and thoughtful product designs help us provide reliable, high-performance solutions.

Reducing Waste

Made to Order

Our panels are manufactured to order, ensuring minimal waste. This custom approach means minimal off-cuts and no unnecessary waste, as each panel is designed to fit specific job requirements perfectly.

Fully Reusable

KOROK panels are designed for reuse. They can be taken down and reassembled multiple times, making them ideal for reconfiguring warehouse or retail spaces. This reusability significantly enhances their ecological friendliness, reducing the need for new materials and minimising waste.

Fully Recyclable

When a KOROK panel reaches the end of its life cycle, it doesn’t need to end up in a landfill. The panels can be disassembled for recycling: the concrete core is crushed and repurposed, and the steel casing is recycled. This closed-loop process ensures that our products contribute to a 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.

KOROK’s Sustainability Journey

Officially Recognised

A DECLARE LABEL ANSWERS THREE QUESTIONS:

1. Where does a product come from?
2. What is it made of?
3. Where does it go at the end of its life?

Declare is a transparency platform and product database that is changing the materials marketplace.

Fire rated protection of junctions between KOROK® walls and structural steel

Ensuring fire-rated protection for junctions between KOROK® wall systems and structural steel columns and beams is critical for maintaining the integrity of fire protection systems in commercial and residential buildings.

This guide provides a quick reference for builders, engineers, architects, and designers to assess, design, and install fire-rated junctions without compromising the fire protection applied to steel structures. Whether you’re working with steel columns, beams, or other structural elements, KOROK® wall systems offer reliable fire resistance and acoustic performance.

Since fire protection linings and coatings are designed to meet the specific requirements of each column, beam, and loading condition, we recommend consulting your structural engineer or fire engineer for precise junction details.

For more information on fire-rated junction systems and KOROK® fire-rated wall systems, please refer to your project’s design team or review KOROK technical literature.

Installation

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.

CASE STUDY

Auckland Film Studio and Sound Stage

KOROK is proud to have supplied the critical fire and acoustic wall systems for the Auckland Film Studio and Sound Stage project. Designed by Ignite Architects and built by Haydn & Rollett Construction, this facility sets a new standard in the New Zealand cinema industry.

KOROK’s Contribution

Our 78mm KOROK panels Gen 2 were chosen for their superior fire and sound-rated properties, achieving a Noise Criterion rating below NC-20. This was crucial in ensuring optimal recording conditions, despite the studios’ proximity to urban noise sources like Auckland’s western rail line.

Sustainable Design and Construction

The project has been awarded a 4 Green Star As-Built rating, recognizing its sustainable design and construction practices.

KOROK is honoured to contribute to a project that not only pushes the boundaries of film studio design but also promotes sustainability and economic growth in Auckland. We look forward to seeing the long-term benefits this project will bring to the local community and the entertainment industry.
