What is a potential consequence of neglecting air barrier maintenance?

Neglecting air barrier maintenance can lead to long-term air quality issues, which is a critical concern for both building occupants and the overall performance of the structure. Air barriers are essential components in controlling the flow of air between the interior and exterior environments. Over time, if these barriers are not properly maintained, they can develop leaks or become damaged, allowing uncontrolled air infiltration and exfiltration.

This scenario can introduce outdoor pollutants, allergens, and moisture into the building, leading to issues such as mold growth, indoor air pollution, and decreased overall comfort for occupants. Furthermore, compromised air quality can have lasting health implications, affecting respiratory health and overall well-being. Maintaining air barriers helps ensure that these systems function effectively, preventing such long-term consequences and promoting a healthier indoor environment.
