Fire Rated Ceiling Air Valves - TENMAT

The TENMAT FIREFLY Fire Rated Ceiling Air Valves are a unique and cost effective alternative to air valves with fire dampers. The TENMAT Fire Rated Ceiling Air Valves are available in all sizes for both Extract & Supply. The Fire Rated Ceiling Air Valves offer a fire rated solution where recessed ceiling air valves are to be installed in fire rated ceilings. In a fire situation, the integral intumescent material rapidly expands to seal off the air valve and reinstate the fire resistance rating of the ceiling. This limits the risk of fire and heat spread throughout the building.

The Fire Rated Ceiling Air Valve is installed as normal with air flow through the air valve unaffected. The product also requires no maintenance unlike many fusible link fire dampers. The Fire Rated Ceiling Air Valves would be required in many domestic homes, as well as apartments, hotels and other multiple occupancy buildings where fire ratings exist.
