Norseal TENMAT Fire Rated Extract Valve 125mm
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 and 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.
