In multilevel buildings such as apartments and hotels, traditional framed wall systems often depend on wall linings to achieve fire resistance and effective acoustic control. However, KOROK® has designed an innovative solution: KIR KOROK® Intertenancy Residential Walls. These advanced wall systems eliminate the need for linings in the ceiling plenum while maintaining exceptional fire resistance and acoustic performance.
This breakthrough simplifies the design, detailing, and construction of intertenancy apartment walls, leading to quicker construction times, less material waste, and significant cost savings.
Key Benefits of KOROK® Intertenancy Apartment Walls:
- Proven fire-rated protection and acoustic insulation for multilevel buildings.
- Solid wall construction for enhanced security and long-term durability.
- Faster installation process, reducing overall project timelines.
- Eco-friendly solution with waste reduction.
