Blower Door Test in Gladwyne, PA

How Is A Blower Door Test Conducted?

To carry out blower door test in Gladwyne, PA, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in PA climates.
