Cavities: Nullifire FV050 is a fire-resistant barrier and intumescent material used for sealing joints and penetrations in fire-rated walls, floors, and ceilings. It is designed to provide fire protection by expanding under heat to close off gaps and prevent the passage of flames and smoke. FV050 is used in a variety of applications including firestopping and passive fire protection, offering excellent performance in maintaining the integrity of fire-rated structures. It is suitable for use with various building materials and is ideal for projects requiring compliance with strict fire safety standards.

How does FV050 work?

The barrier allows for airflow under normal conditions but expands during a fire to seal the cavity, preventing the passage of fire, smoke, and heat.

How is FV050 installed?

• Measure and cut the barrier to fit the cavity size
• Attach the FV050 barrier to the cavity using mechanical fixings or in accordance with manufacturer instructions
• Ensure proper positioning to maintain airflow and fire safety

Does FV050 affect ventilation?

No, FV050 is designed to allow ventilation in normal conditions while providing fire resistance when required, without blocking airflow.
