Blower Door Test in Southampton township, NJ

How Is A Blower Door Test Conducted?

During blower door test in Southampton township, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.
