There are three main types of air ducts: sheet metal, pre-insulated, and flexible duct work.
Sheet metal air ducts can be made of galvanized steel or aluminum, and may be insulated inside or outside with fiberglass.
There are pre-insulated air ducts, which are relatively inexpensive to install, made of fiberglass duct board, polyurethane foam panels, or phenolic foam panels.
Air ducts can also be flexible ducts, made of flexible plastic over a wire coil.
