Air leakage, or infiltration, occurs when outside air enters a house uncontrollably through cracks and openings. Properly air sealing can significantly reduce heating and cooling costs, improve building durability, and create a healthier indoor environment. In addition to air sealing, you'll also want to consider adding additional insulation and moisture control and ventilation strategies to ensure your home is comfortable and efficient.
