Blower Door Test in Spring Lake Heights, NJ

How Is A Blower Door Test Conducted?

For blower door test in Spring Lake Heights, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. 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 sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.
