Blower Door Test in Seaside Heights, NJ

How Is A Blower Door Test Conducted?

Before blower door test in Seaside Heights, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. 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 pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.
