Blower Door Test in Vineland city, NJ

How Is A Blower Door Test Conducted?

When conducting blower door test in Vineland city, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. 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.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.
