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. It is also tested to be used as cable trunking infill.
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, giving a dry fit fire stopping solution that is easy to cut and handle, compressible and lightweight.
