Nullifire FZ400 Movement Joint Filler

Nullifire FZ400 Movement Joint Filler is a revolutionary fire protection solution, tested for use in linear joints (both vertical and horizontal) and as a method to provide penetration seal movement around and at the head of Nullifire FB750 Intubatt. Nullifire has developed a ground breaking and unique fire stopping technology: GXT (Graphite expansion Technology). GXT has been incorporated within Nullifire FZ400 inside a water resistant sleeve.

BENEFITS:

- Up to 2 hours fire resistance - Tested to EN 1366-3 and 4
- Unique GXT technology
- Ideal for areas with high vibration and movement requirements
- Simple to install: dry fit, easy to cut and handle, compressable, lightweight
- Creates a seal that permits service movement
- Tested with mixed services: suits vertical & horizontal wall joints, floor seals, and head of wall movement scenarios
- Tested as a linear gap joint - superseding FJ400

RECOMMENDED FOR:

- Tested and suitable to be installed around, and to the head of, FB750 Intubatt service penetration seals. The product will allow and absorb any deflection, differential and service movement up to ±30mm (tested) and up to ±60mm (theoretically). FZ400 has been cyclic tested and subsequently fire tested with the inclusion of service penetrations
- Can be used to reinstate the performance of fire compartment lines, both walls and floors, where construction joints require a physical movement seal and a specific fire rating
- Has been tested in linear joints up to 115mm gap width in walls / 150mm gap width in floors
- It is tolerant of very large movement and is used in areas where standard mastic joints are not suitable. FZ400 offers a solution for areas subject to regular cycles of expansion and contraction or vibration, in compression, where reliability is vital
