Blower Door Test in Bellmawr, NJ

How Is A Blower Door Test Conducted?

For blower door test in Bellmawr, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.
