Air infiltration is the exchange of air through cracks and gaps in the outside shell of a home. Infiltration increases heating and cooling costs and reduces the comfort level of occupants. Loose fitting windows and doors, cracks between the house and the foundation, and gaps around plumbing and electrical penetrations are typical sources of leaks.
Reducing air infiltration is often the first action item of a weatherization plan. Caulking cracks, sealing an unused fireplace, and adding weather stripping are the most significant improvements that can reduce air infiltration.
