Duct Mastic

Duct leakage is a major problem with forced-air heating or air-conditioning systems. When ducts are run outside of the conditioned space, heating and cooling efficiencies may be cut in half due to leakage. Tightly sealed ducting is extremely important in ensuring high energy efficiency of forced-air HVAC equipment. Experts strongly recommend flexible duct mastics—not duct tape—for sealing ducts, as mastics last longer under high temperatures. In some applications, however, the messiness of mastics can be a problem.
