Suitable for timber joist floor/ ceiling constructions, metal web joist and I-beams.

Astroflame’s Fire Rated Air Valves are a unique and cost effective fire rated solution where recessed ceiling air valves are to be installed in fire rated floor/ ceiling constructions. In a fire situation, the integral intumescent material rapidly expands to seal off the air valve to help maintain the fire resistance rating of the ceiling. This limits the risk of fire and heat spread throughout the building. The Astro FR Ceiling Valve are available in all common sizes for both Extract and Supply.

The Fire Rated Air Valve is installed as normal with air flow through the air valve unaffected. The product requires no maintenance after installation. The Astro FR Ceiling Valve suitable for domestic homes, as well as apartments, hotels and other multiple occupancy buildings where fire ratings exist.
