FB750 Intubatt Coated Batt 1200mm x 600mm x 50mm
Nullifire FB750 Intubatt is a lightweight fire barrier comprising of a rock mineral fibre board with a uniquely identifiable ablative coating. FB750 is designed to reinstate the fire performance of compartment walls and floors that have been breached, providing a fire, smoke, thermal, acoustic and air pressure seal.
Our excellent formulation also incorporates a unique identification property offering architects, specifiers, main contractors, and applicators guaranteed traceability of product on-site. Optifire technology is activated by exposing the products surface to a UV light source, which offers easy and instant product identification. Nullifire FB750 also features Optifire+ visible with a Nullifire detector offering lifetime identification, even after a fire.
FB750 must be used alongside FS702 Intumastic Fire Resistant Acrylic Sealant 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 and cable bundles up to 100mm.
Recommended areas of use
Flexible and rigid walls (90mm or wider)
Rigid floors (150mm or wider)
Beneath raised access floors or suspended floors and ceiling voids, as a continuation of the fire compartment.
When used with a Nullifire closer device (FS709 HP, FP302, Intustrap, FP220 Service Sleave, FP170) FB750 Intubatt also becomes suitable for penetrating combustible services and conduits such as PVC, PE, PP, HDPE, PPR, PEX, Uponor and combustible ducting.
Typical areas of use include health and leisure facilities, schools, universities, commercial buildings, hospitals, retail and industrial units and nuclear powerplants
