Blower Door Test in Point Pleasant Beach borough, NJ

How Is A Blower Door Test Conducted?

To conduct blower door test in Point Pleasant Beach borough, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. 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 indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.
