Scissor Stair Systems

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.
