HOW TO: Install the CFS-B firestop bandage
To offer a suitable and flexible solution, Hilti has developed the Firestop Bandage CFS-B. It is only 2mm thick and already comes at a depth of 125 mm. This geometry makes it more flexible and easier to install, thus reinstating the fire performance of the wall or floor. The CFS-B Firestop Bandage can be used for both single or multiple penetrations and can be easily cut to fit the outside diameter of an insulated pipe. The attachment to the insulation is achieved with a steel band or wire, which is supplied with the product. To make sure the system is smoke-tight, Hilti Firestop Acrylic Sealant CFS-S ACR can be used to close the remaining annular gap.
