What is air leakage? Ventilation is fresh air that enters a house in a controlled manner to exhaust excess moisture and reduce odors and stuffiness.Air leakage, or infiltration, is outside air that enters a house uncontrollably through cracks and openings. It is unwise to rely on air leakage for ventilation. During cold or windy weather, too much air may enter the house and, during warm or calm weather, too little.Also, a leaky house that allows moldy, dusty crawlspace or attic air to enter is not healthy.
