Intertenancy Fire and Acoustic Rated Protection

In terraced housing and town houses, conventional framed wall systems rely on the internal linings for fire-resistance. Penetrating these linings potentially destroys the fire-rated barrier. In the KOROK® Intertenancy System the main fire barrier located between frames is designed to protect the structure on the side opposite the fire.

KOROK® aluminium brackets attach the KOROK® panels to both frames. As the fire increases, the aluminium brackets on the fire side melt, allowing the structure on the fire side to detach. This leaves the KOROK® panels supported by aluminium brackets connected to framing on the non-fire side.
