Kitchen Extraction requires different critical features to a ductwork system to enable optimum use and fire resistance.
The ductwork should be tested for both type A fire outside and type B fire inside, and this makes Flameshield Fireduct the perfect ductwork for such applications, with compliance and successful results for both tests.
Fire dampers should not be used in this instance due to the high operating temperatures within the duct and also the potential build-up of grease could prevent the damper from closing fully.
