Blower Door Test in Wallington, NJ

How Is A Blower Door Test Conducted?

During blower door test in Wallington, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.
