FB750 Intubatt & Applications

Much more than a simple batt, this is your fire stopping go-to and most tested product with the wider scope of applications from Nullifire!


FB750 Intubatt Coated Batt is a rock mineral fibre board with a uniquely identifiable ablative coating. It is used to reinstate the fire performance of the substrate when it has been breached by service penetrations.

The most versatile fire stopping product in our range, FB750 is suitable for use in flexible & rigid walls, rigid floors and under timber floors. And, it can be used on its own for blank seals, cables and cable trays, plus insulated and uninsulated non-combustible pipes.

FB750 is now lighter, less fragile, as well as easier to cut and handle. Still, with the same rigorous testing and certification!
