What can result from improper air barrier installation?

Improper air barrier installation can lead to an increased risk of mold growth due to air leakage and the infiltration of moisture into building assemblies. Air barriers are designed to control air movement through the building envelope, which is crucial for maintaining appropriate humidity levels. When there are gaps or improper seals in the air barrier, moisture-laden air can infiltrate walls, ceilings, and other areas, creating an ideal environment for mold spores to thrive. Over time, this can lead to serious health issues, structural damage, and increased repair costs.

Inadequate air barriers also fail to effectively regulate temperature and humidity, which can further contribute to mold problems. By ensuring that air barriers are installed correctly, building professionals can mitigate these risks and promote healthier indoor environments.
