FB750 Intubatt

FB750 Intubatt is a lightweight fire barrier comprising of a rock mineral fibre board with an uniquely identifiable ablative coating, containing Optifire unique traceability identifier.

Usage/purpose

FB750 Intubatt 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 can be used on flexible walls & rigid walls (70mm or wider), rigid floors (100mm or wider), beneath raised access floors / suspended floors and ceiling voids, CLT walls & floors, white walls, to reinstate a breached fire compartment.

FB750 Intubatt has been tested in conjunction with Nullifire closer devices (FS709 HP, FP302 Intustrap, FP220 Service Sleeve, FP170 Intucollar, FS719 Blue, FP333 Trunking Infill), to seal penetrating combustible services & conduits such as PVC, PE, PP, HDPE, PPR, PEX, PB, Uponor and combustible ducting, electrical trunking, and combustible insulation around pipes, multiple busbars.

FB750 may be used without a closer device for sealing around the following service types: non-combustible pipes, non-combustible pipe insulation, cable trays, ladders and baskets (perforated or non-perforated), armoured cables, data cables, HV cables, cable bundles up to 100mm, single busbar.

FB750 has also been tested to fire protect the underside of loaded timber floors for up to 120 minutes (BS 476 Pt 21).

Typical areas of use include: health and leisure facilities, schools, universities, modular construction, commercial buildings, hospitals, retail and industrial units, train stations, nuclear power plants, etc...

Always read SDS, pre-application guidance and relevant application detail prior to application. Ensure the latest documents are downloaded prior to every project commencement.

FB750 Intubatt requires the use of FS702 Intumastic and FS712 Intucoat Brush for adhesion, bonding and sealing.
If access to seal is only available from a single side, contact Nullifire Technical team for fully tested details.
This product should not be in direct contact with CPVC pipes; FS719 HP Blue for CPVC should be used on the full depth of the FB750 Intubatt, to the correct annular space.
If used around Pegler X-Press Carbon Steel pipes, the pipe manufacturer should be consulted, and their recommendations followed.

Safety data sheet must be read and understood before use.
