This report summarizes the potential for new technologies for ducts, duct fittings, and insulation. It begins with a review of what technology is currently in use or available and found that the only inexpensive ducts in production are insulated wireflex ducts, sheet metal ducts, fiberglass board ducts, and uninsulated plastic ducts. For duct fittings, the market was found to be dominated by sheet metal fittings with some use of ductboard. Fittings that snap together were found for use with steel ducts but are too expensive for a residential setting. An uninsulated sheet metal duct which uses a rubber gasket was also found. Two companies are trying to develop plastic fittings, but their designs don’t consider improving the method of attachment to wireflex duct.
