We are leading manufacturer of the duct line. With forced-air systems, the ducts that carry the heated or cooled air throughout the area unconditioned spaces where temperatures are quite different from that of the air in theducts. These temperature differences can affect the temperature of the air passing through the ducts and increase heating and air conditioning costs.
Insulating ducts in unconditioned areas can help to reduce space heating and cooling energy costs and improve indoor comfort. In humid climates, properly installed duct insulation can also reduce moisture condensation on metal ducts.The recommended amount of duct insulation, shown in the table below, varies depending on your climate and the location of the ducts.
