Fire rated ceiling valve usage is constantly growing in domestic and commercial properties. Protection against fire should always be a concern and all safety measures should be considered.
These fire rated ceiling valves have a 60 minute rating, which prevents fire spreading through ceilings. In case of a fire the intumescent pad inside the ceiling valve expands and prevents fire spreading through a building.
The Kair fire rated supply valve incorporate integral intumescent materials. During a fire, the intumescent material expands and closes the apeture of the valve, re-instating the fire resistance of the structure.
