The Thermaflex Pro Series commercial flexible duct line offers three insulated models and three uninsulated models. All of the Pro Series ducts feature heavier coated wire that won’t corrode or weaken, components that are self-extinguishing and won’t support flame, and tough vapor barrier construction, states the company. According to the manufacturer, the insulation on the ducts provides superior heat transfer properties and does not support mold or bacterial growth. All Pro Series products are backed by a 10-year warranty.
