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.

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.
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.
