Air leakage through air/vapor barriers (AVBs) can significantly reduce a building’s energy efficiency and long-term performance. Bubble gun testing, as described in ASTM E1186, is a highly effective, visual method for detecting membrane defects—before finishes or cladding conceal them.
Bubble gun testing, in accordance with ASTM E1186, uses controlled air pressure and a soap-based solution to identify breaches in air barrier systems. At Atlantic Testing Services, we utilize the PosiTest® Air Leak Tester, which creates a localized depressurized zone on the exterior surface of the AVB.
Once a biodegradable surfactant solution is applied to the membrane, the PosiTest device draws air from the test area. If any leaks or pinholes are present, interior air escapes through the membrane and forms visible soap bubbles—making even the smallest defects easy to detect in real time.
Atlantic Testing Services brings certified adhesion testing to job sites across the U.S. Our team ensures you meet industry standards, installation specs, and energy code requirements—with documentation you can trust.
