Last week we performed air leakage and water leakage testing at a new construction office building in Indianapolis. The project involved chamber testing per ASTM E1186, utilizing a liquid solution and smoke to identify air leaks in a wall assembly.
A 10′ x 10′ air-tight chamber was constructed and sealed tightly to the exterior wall assembly. A small fan was used to pressurize and de-pressurize the chamber while a technician used a smoke puffer and liquid solution inside the chamber to identify air leakage sites.
Using a hi-lift, we performed a water leakage test following AAMA 501.2 testing guidelines. Horizontal and vertical seams were checked utilizing a calibrated sprayer unit.
