Blower Door Test in North Wildwood, NJ

How Is A Blower Door Test Conducted?

In blower door test in North Wildwood, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.
