Nullifire FO400 H&V Foil Tape - 50mm x 50m

The Nullifire FO400 H&V Foil Tape is a high-performance sealing tape specifically designed to secure and protect the cut ends of Nullifire FZ400 movement joint fillers. It instantly restores the integrity of cut FZ400 movement joint fillers, ensuring they remain secure and contained during dry-fit compression within passive fire protection systems.

• Prevent installation failure: Securely reseals modified FZ400 bags to contain intumescent material and prevent snagging or tearing during dry-fit insertion.
• Maximise efficiency: The heavy-duty foil construction adheres instantly to the bag material, saving you time when modifying movement joint fillers on-site.
• Ensure system compliance: Meets the manufacturer's strict installation criteria for resealing open ends on FZ400 movement joints prior to installation.

When installing the Nullifire FZ400 movement solution, custom cutting is often required to fit specific apertures or form butt joints. Applying FO400 Foil Tape to these exposed ends is a mandatory step to maintain the integrity of the protective bag under a minimum 10mm compression. This straightforward step guarantees the movement joint performs exactly as tested within the overarching fire stopping framework.
