KOROK® has 2-way fire-rated wall systems for fire separation of Scissor Stairs or any Stairs.

Our innovative KOROK® Scissor Stair wall systems are BRANZ-tested and Warringtonfire-assessed, ensuring compliance with New Zealand’s fire safety standards. These systems are rated up to a Fire Resistance Rating (FRR) of -/120/120, offering robust protection for critical building areas. KOROK® Scissor Stairs Systems cater to most common scenarios requiring fire resistance in stair configurations. These walls are constructed using 78mm thick, horizontally and/or vertically oriented KOROK® panels, designed to fit seamlessly between two independent stair stringers in scissor stairs configurations. The systems feature self-supporting, non-load-bearing walls that can be built using horizontally or vertically stacked panels, or a combination of both. This flexibility ensures adaptability to a wide range of building designs.

Key Benefits of KOROK® Scissor Stairs Fire-Rated Wall Systems:

• Two-way fire protection: Rated up to FRR -/120/120 for comprehensive fire separation.
• No height limitations: KOROK® walls can be installed without restrictions on wall height, in both horizontal and vertical configurations.
• Structural simplicity: No additional structural support required beyond attachment to stair landings and stair stringers.
• Fast, efficient installation: Lightweight interlocking panels make installation faster and more cost-effective compared to conventional systems.

KOROK® Scissor Stairs wall systems combine fire safety, acoustic performance, and cost efficiency, making them the ideal choice for builders and developers.

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.

Boathouse Bay: A Showcase of Sustainable Community Living

Located at Snells Beach, just north of Auckland, Boathouse Bay by Crosson Architects has set a new standard in environmentally-conscious design, winning the prestigious title of Home of the Year 2024. This award-winning project offers a perfect blend of architecture and nature, creating a community-focused environment that celebrates New Zealand’s coastal lifestyle.

Innovative Design with a Coastal Influence

Inspired by the traditional Kiwi bach, Boathouse Bay reflects simplicity and connection to nature. The development embraces natural materials, muted tones, and open communal spaces, fostering a sense of unity among its residents. The layout encourages interaction, with thoughtfully designed pathways connecting homes to shared outdoor areas, reinforcing the idea of community living.

KOROK’s Role in Enhancing Safety and Sustainability

Central to Boathouse Bay’s design is the use of 51mm KOROK Intertenancy Terraced Housing Systems, which offer superior fire protection without compromising the project’s environmental goals. Our fire-rated systems ensure that the development remains safe, durable, and sustainable. The aluminum brackets included in the KOROK system safeguard the structure in the event of a fire, reinforcing both safety and structural integrity for terraced housing.

Setting a Benchmark for Future Living

Boathouse Bay is more than just a residential development—it’s an example of how modern, community-focused living spaces can integrate sustainability, safety, and social interaction. As the Home of the Year 2024, it stands as an inspiration for future projects that aspire to merge contemporary design with environmental stewardship.

Hobsonville Point: Enhancing Fire and Acoustic Protection with KOROK® Intertenancy Systems

Bringing Kiwi Ingenuity to Hobsonville Point Homes

Here at KOROK®, we’re stoked to have been part of the transformation of the old Hobsonville airbase into a new community. Our innovative KOROK KIR Intertenancy Residential Walls have been key in shaping around 3000 homes across this significant slice of land, including standout spots like the Te Uru Apartments, Walter Merton Road Terraces, Nugget Avenue Terraces, and Buckley A Precinct.

Being part of the Hobsonville Point development really showcases our ability for coming up with smart solutions that tackle the real-world challenges of modern building, especially when it comes to keeping fires at bay and cutting down on noise. Traditional wall setups in flats and hotels usually lean on linings to do this job. But our KIR walls change the game by ditching the need for these linings up top, making the whole building process simpler and slicker.

Smoother Sailing in Building and Design

Our walls have made it quicker and easier to get buildings up at Hobsonville Point. That’s good news for the teams on the ground and means residents can start enjoying their new digs sooner.

Keeping Costs Down

Thanks to the technology behind our KIR panels, we’ve cut down on waste, which means saving some dollars. Those savings can help make other parts of the development even better, making the whole neighbourhood a top spot to live.

Top-Notch Fire and Sound Safety

We’ve put our walls through the wringer to make sure they’re up to scratch for fire safety and noise control. That means folks living in Hobsonville Point can sleep easy, knowing they’ve got solid protection around them.

Built Solid for Extra Peace of Mind

The sturdy design of our walls means homes are not just safe but also built to last. That’s a big plus for anyone calling Hobsonville Point home, offering a secure spot for years to come.

Committed to Excellence in Innovation and Community Building

From the lively look of the Te Uru Apartments to the tidy and thoughtful design of the Walter Merton Road Terraces and the spot-on style of Buckley A Precinct, our KIR panels have been a foundation for success, delivering the goods on fire safety and quiet living. As we look back on our role at Hobsonville Point, we’re chuffed to have delivered solutions that not only tick the boxes for what’s needed in today’s building scene but also help forge strong, safe, and green communities. Our dedication to coming up with better ways to do things will keep us at the forefront of making homes better for Kiwis everywhere.
