So, the fire resisting duct needs to maintain i.e., not compromise the fire resistance with the wall or floor by which it penetrates. The overall performance of the fire resisting duct which penetrates a fire resisting/separating aspect necessitates thorough thing to consider by specifiers and controlling authorities. The typical periods of steadiness and integrity should in all conditions be at the least equal to those required with the penetrated ingredient of design.
The fire rated ductwork is sent to web site and equipped as typical ductwork, so obviating the necessity For extra contractors.
Sometimes contractors wrap regular ventilation ducts with Rockwool or non-combustible insulation of any thickness/density.
Any supplemental companies connected to fire ductwork supports might increase mysterious load bearing variables, which in the event of fire may well impression The steadiness of the ductwork just when it is needed most.
