Blower Door Test in Kulpsville, PA

How Is A Blower Door Test Conducted?

For blower door test in Kulpsville, PA, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the PA environment.
