Air Ducts Reference for New Homes

Forced air duct systems should be permanently sealed using a duct sealer on all connections and joints.

Airtight ducts are essential for proper system operations. Look for other areas that will allow outdoor, basement, or attic air to enter the house, and seal. A whole-house approach to building will result in good health/safety, durability of the structure, comfort of the occupants, and long-term efficiency.
