Air barrier

Building assembly components that work as a system to restrict air flow through the building envelope. Air barriers may or may not act as a vapor barrier. The air barrier can be on the exterior of the assembly, the interior, or both.

Air leakage testing is the process in which the building enclosure is quantitatively measured for leakage, typically to determine how much energy could be lost through discontinuities in the air barrier. This testing has been a part of residential energy audits for more than 30 years, but relatively very little quantitative testing has been done on large buildings.
