Intertenancy Apartment Systems Fire and Acoustic Rated Protection

Fire and Acoustic Rated Protection for Intertenancy Apartment Systems

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..

Intertenancy Terraced Housing Systems Fire and Acoustic Rated Protection

Intertenancy Terraced Housing Systems – Fire and Acoustic Rated Protection

In modern terraced housing and townhouses, traditional framed wall systems depend on internal linings to provide fire resistance. Any penetration through these linings can compromise the fire-rated barrier, increasing the risk of fire spread. The KOROK® Intertenancy System offers a superior solution, where the primary fire barrier is located between the structural frames, protecting the building on the side opposite to the fire.

How KOROK® Intertenancy Systems Work

The KOROK® Intertenancy System utilizes aluminium brackets to attach the KOROK® fire-rated panels to both frames. In the event of a fire, the brackets on the fire-exposed side melt, allowing the structure on the fire side to detach safely. This innovative design ensures that the KOROK® panels remain securely supported by the brackets connected to the non-fire side, providing continued fire protection and maintaining the integrity of the structure.

Acoustic and Fire-Rated Solutions for Terraced Housing

In addition to superior fire resistance, the KOROK® Intertenancy System offers excellent acoustic insulation, making it an ideal solution for townhouses and multi-residential developments. By minimizing noise transfer between units, the KOROK® system enhances privacy and comfort for occupants.

KOROK® Cantilever Design

The KOROK® Cantilever feature in the Intertenancy Terraced Housing Systems ensures that the panels remain stable during a fire, further enhancing the safety and reliability of the system. This design meets strict building code requirements and is fully tested to withstand fire scenarios. KOROK® Cantilevers
