TENMAT's comprehensive range of EN tested Fire Rated Air Valves
05 March 2013
Recessed ceiling air valves are widely used in both domestic and commercial buildings. Once a hole is made in a ceiling for an air valve, the integrity of the construction and its ability to perform in a fire is reduced significantly. Ceiling air valves, if left unprotected, allow a fire to spread rapidly through a building. Ceilings must be fire protected in accordance with Approved Document B of the Building Regulations, which states the ceiling must be firestopped to reinstate the original fire rating.
