Air Barrier Testing, ABAA Certified
Air barriers control air leakage into and out of the building envelope. Air tightness testing is a process in which the building envelope is tested to quantify the air tightness. The test measures air leakage rates through a building envelope under controlled pressurization and depressurization.
Building testing is not a mandatory test prescribed in building codes, but a performance-based option that an increasing number of designers are requiring (see below).
