Power Inverter Air Conditioner. Ductwork.
Ducts are wrapped with insulation to increase the efficiency of an HVAC system. As the hot air travels from the furnace through the conduits to various locations in a home, the aluminum ducts emit some heat to the basement or vent. This phenomenon is particularly problematic during the cold winter if a house is built in ventilation space instead of a basement controlled environment. Heat pipes wrapped also reduce the amount of sound transmitted through the ducts in the house.
Identifies ducts basement or crawl spaces to be covered. Main duct leading from the top of the furnace along the center line of the basement. They are square and are fitted below the floor joists. Individual room ducts are round and head of the main line to the rooms. They are usually installed to lie between the floor joists.
Cut strips of 16 inches wide insulation blue foam board to insulate round ducts. Also cuts strips fiberglass insulation which are of the same length as the conduit. Sliding the fiberglass insulation in the cavity around the conduit and placed staples in place. Kraft paper facing the insulation is small paper tabs along each edge that can be stapled to the floor joist to keep it in place.
Cavity includes nailing blue foam board on fiberglass insulation. Nail the foam board to the floor joists with roofing nails with large heads. This double insulation prevent sound transmission and heat loss.
