Air Transport

Air transport is defined as the movement of moisture in the air. Controlling air transported moisture is key to controlling moisture in the house. An air barrier system consists of materials that enclose a volume of air with minimal air leakage between the enclosed air and the outside air. Examples of moisture transported by air include:

  1. Outside air with high relative humidity that gets inside when doors are opened
  2. Inside air that has a high relative humidity from daily activities such as bathing, showering, laundry, cleaning, cooking, or dish washing
  3. Air leaks around windows, doors, floors, etc.
  4. People, pets, and plants add moisture to the inside air
  5. Leaky ductwork allows outdoor air with excessive moisture to enter a house
