Blower Door Test in Wrightstown, NJ

How Is A Blower Door Test Conducted?

When performing blower door test in Wrightstown, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. 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.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Wrightstown, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities.
