    Flame retardant duct require the usage of flame retardant pvc tarpaulin materials for construction or use around sensitive equipment. To be classified as flame retardant, material must be exposed to a flame and stop burning after the fuel is taken off the material. You should use fire rated ductwork once the flexible ducts are put around flammable materials to be able to reduce the risk of fire.
