Product Description

FB750 is designed to reinstate the fire performance of compartment walls and floors which have been breached by penetrating services, providing a fire, smoke, thermal, acoustic and air pressure seal.

FB750 must be used in conjunction with FS702 Intumastic to be suitable for sealing around the following service types: non-combustible pipes, cable trays, ladders and baskets (perforated or non-perforated), armoured cables, data cables, HV cables, cable bundles up to 100 mm.

FB750 can be used on flexible walls & rigid walls (100 mm or wider), rigid floors (150 mm or wider), and beneath raised access floors / suspended floors.

When used with a Nullifire closer device (FS709 Intumastic HP, FP302 Intustrap, FP160 Intusleeve, FP170 Intucollar), FB750 Intubatt also becomes suitable for penetrating combustible pipes & conduits such as PVC, PE, PP, HDPE, PPR, PEX, Uponor and combustible ducting.
