Blower Door Test in Voorhees township (Camden), NJ

How Is A Blower Door Test Conducted?

While performing blower door test in Voorhees township (Camden), NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. 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.

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. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.
