What is a potential issue with improper connections in an air barrier system?

Improper connections in an air barrier system can create significant problems, particularly leading to air leakage. An air barrier is designed to limit uncontrolled air movement between the interior and exterior of a building. When the connections between different air barrier components are poorly executed, gaps and seams can form that allow air to infiltrate or exfiltrate. This can compromise the overall effectiveness of the air barrier, resulting in increased energy costs, reduced indoor air quality, and potential moisture issues that may impact the durability of building materials.

Effective connections are essential to maintain the integrity of the air barrier, and any shortcomings at these junctions can severely undermine the system's performance. Addressing these issues often requires more extensive repairs and can be quite complex, countering any notion that they are easy to fix. Also, while aesthetics may be a consideration in building design, the functionality and performance of the air barrier take precedence over visual appeal. Furthermore, the impact of improper connections extends beyond material costs, as air leakage can lead to energy inefficiencies and higher operational expenses.
