Blower Door Test in Hi-Nella borough, NJ

How Is A Blower Door Test Conducted?

To conduct blower door test in Hi-Nella borough, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.
