SIDERISE RF cavity barrier and firestop systems prevent the spread of fire and smoke, and reduce sound transmission, by sealing the voids between raised access floors and floor slabs.

The range includes options to either subdivide large uninterrupted cavities or to provide continuity of fire resistance when aligned underneath partitions. Across the range, these simple to install systems have been tested for fire performance, acoustic performance and for use as a plenum liner.

This fire safe insulation has been designed as a one-piece system and afford easy cutting and installation. Additionally, due to a patented method of manufacture, the products also offer unique vertical compression to allow tightness of fit.
