What can inadequate air barriers lead to in environments with high humidity?

Inadequate air barriers in environments with high humidity can lead to significant problems such as water damage, mold growth, and deteriorating air quality. When air barriers are not properly installed or maintained, they allow moisture-laden air to infiltrate the building envelope. This increased moisture can condense on cold surfaces, promoting mold growth and potentially leading to structural damage from water accumulation. Additionally, high humidity levels can create an environment conducive to various indoor air quality issues, as mold spores and other contaminants may flourish in such conditions.

This understanding highlights the importance of adequate air barrier systems in buildings, especially in humid climates, to prevent moisture-related problems that can adversely affect occupant health and the structural integrity of the building.
