Blower Door Test in Monroe township (Gloucester), NJ

How Is A Blower Door Test Conducted?

To carry out blower door test in Monroe township (Gloucester), NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.
