These air valves should be protected to eliminate the potential for rapid fire spread. Our fire rated ceiling air valves are an easy and effective solution. Our valve is also a less costly alternative to metal fire rated valves and fire dampers. After installation, the ceiling valve is effectively protected, yet air flow is kept in accordance with approved document B of the building regulations.
If a fire occurs, the fire rated ceiling air valve automatically seals itself. The spread of fire via the protected air valve is prevented. Tested to BS EN 1365-2 for up to 60 minutes of fire exposure. Installation identical to a standard air valve. Suitable for retrofit scenarios.
