Scissor Stairs – Fire and Acoustic Rated Protection

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.

Compliance with the New Zealand Building Code

KOROK® Scissor Stair Systems meet the stringent requirements of Clause C of the New Zealand Building Code (NZBC). They comply with the normative requirements for fire resistance performance as outlined in New Zealand’s acceptable solutions.

Fire Resistance Ratings (FRR)

The fire resistance ratings of KOROK® Scissor Stair Systems reach up to FRR -/120/120, depending on the span of the panels and the components selected.

• Horizontal Fire Resistance: Achieved by the quadrilateral fire-resistant section between the two independent stairs.
• Vertical Fire Resistance: Provided by the wall-to-stair stringer angle at the boundary connections.

For detailed configurations, refer to the technical specifications in the KOROK® Scissor Stair Systems wall type tables.
