Nullifire FZ400 Movement Joint Filler - 80mm x 50mm x 1m

Nullifire FZ400 is a revolutionary fire-stopping strip designed to seal linear gaps and service penetrations where structural movement is expected. Engineered with Graphite eXpansion Technology (GXT), it maintains a robust EI120 fire rating even when subjected to vibration or head-of-wall deflection.

• Accommodate high movement: Tested to absorb ±30mm deflection, preventing the fatigue and cracking common with standard mastic seals.
• Install in seconds: The compressible dry-fit foam requires no tools, sealants, or masking tape, significantly reducing labour time on large projects.
• Ensure total compliance: Fully tested to EN 1366-3 and EN 1366-4 for use in walls, floors, and around FB750 Intubatts.

This unit supersedes the FJ400, offering superior elasticity for dynamic environments like airports, hospitals, and high-rise buildings. It features a water-resistant sleeve for Type X durability (weather exposure), making it suitable for damp conditions while acting as an effective cold smoke seal.
