The AeroBarrier system uses a standard blower door device to measure envelope leakage in real-time during the process. The system tracks air leakage using three different metrics: Normalized Leakage Area (in square inches), Leakage Volume Rate (in cubic ft/min or CFM) and Air Change per Hour at 50 Pascals of pressure (or ACH50).

The blower door device is calibrated to meet ASTM Standard E779, E1554, CGSB-149.10-M86, EN 13829, ATTMA Technical Standard 1, NFPA 2001, RESNET and USACE.
