Blower Door Test in Wildwood Crest, NJ

How Is A Blower Door Test Conducted?

To conduct blower door test in Wildwood Crest, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. 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 nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.
