A system for providing more efficient insulation for heating and air conditioning ducts is disclosed. Specifically, a system comprising one or more layers of light-weight, rigid spacers made of non-conductive material attached over an air duct, is disclosed. The spacers contain air channels or air spacers, and can be pre-attached to the air duct prior to installation of the duct. The air duct/spacer combination is wrapped with reflective insulation material.
