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
