Hilti CFS-HFF Firestop Rib Filler is a smoke and sound-seal that can be used with Tata Steel’s ComFlor® 51+ metal decking to seal the unused rib space of the profile. This offers additional fire resistance and sound absorption. The inserted Rib Filler acts as a firestop barrier when used in applications such as basic and deflection head walls.
Developed by Hilti, the pre-formed polyurethane foam filler is designed to offer increased fire protection/resistance. Following stringent testing at Warrington Fire UK the Firestop Filler is now fully approved and certified for use within the UK market up to an EI 120 requirement, depending on build type.
Tested under a range of different scenarios, thickness and types of wall coverings, the fire ratings achieved EI (E=integrity: I=insulation) classifications of 30, 60 and 90, as shown below:
