Blower Door Test in Glassboro, NJ

How Is A Blower Door Test Conducted?

For blower door test in Glassboro, 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 picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. 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 pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.
