Smoke exhaust ductwork systems are used to extract smoke and fumes from a building.
Ductwork used in smoke exhaust systems should normally be rated for stability, integrity and insulation at least equal to the compartment wall through which it passes.
Industrial / Office exhaust ductwork must be suitable for removal of smoke within the compartments. Normally, this is rated to provide two hours of stability and integrity to resist heat, smoke and fire from inside.
However, a fire engineered solution designed by a qualified fire engineering consultant for lower smoke temperatures may be allowed by the regulatory authority, thus reducing the insulation requirement. However, the duct should be tested and installed to maintain stability and integrity to the full test temperature.
