Fire Rated
for penetrations created by Air Vents/Valves fitted in fire rated ceilings.
The Fire Rated Air Valves do not require any additional supports
or fixing and can be fitted as normal.
The unique intumescent gasket material does not restrict the air flow of the air valves.
However, in a fire situation, the material rapidly expands to seal off the open air valve.
The penetration is then sealed against the spread of fire and the fire rating of the ceiling construction is maintained.
