FZ400 Nullifire Movement Joint Filler

Created with unique fire stopping technology, Nullifire Movement Joint Filler provides a penetrative seal, stopping fire in its tracks. FZ400 Movement Joint Filler is 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. It is also tested to be used as cable trunking infill. Provides more time: Up to 2 hours fire resistance - tested to EN 1366-3/4. Unique technology: GXT (Graphite eXpansion Technology) is incorporated inside a water resistant sleeve. Simple to install: Dryfit, easy to cut and handle. Versatile: use on horizontal and vertical wall joints, floor seals and more. Flexible: ideal for areas with movement or vibration. FZ400 is ideally suited to all areas with dynamic live load environment such as airports, train stations, hospitals and high rise buildings. It may also be suitable for buildings being designed for earthquake zones or military buildings designed to withstand high ground movement shockwaves. FZ400 is 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. FZ400 may 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. FZ400 has been tested in linear joints up to 115mm gap width in walls / 150mm gap width in floors. FZ400 has 60% demonstratable compression capability (compress and return). 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. FZ400 is also designed to provide a permanent fire barrier within trunking boxes passing through fire compartment walls. It has been tested within flexible walls.
