Flexible duct is the best option for channeling duct split systems for air sweep. Ease of channeling execution and great useful life are advantages of this type of air ducts. Also tarpaulin ducts are used for channeling exhaust fan systems.
Since the insulation of galvanized ducts during the channeling is too difficult, therefore flexible ducts are used in industrial and structural channeling.
