(1.0 CEU) Ducts located outside the conditioned space need duct insulation. Without insulation, ducts outside the thermal boundary waste energy and don’t deliver conditioned air to inside spaces efficiency. This leads to comfort problems, condensation problems, and high energy bills. This lesson covers when ducts need insulation and how much insulation ducts require. You’ll also learn what other factors you need to consider before you select or install duct insulation.
