Blower Door Test in West Wildwood, NJ

How Is A Blower Door Test Conducted?

When blower door test in West Wildwood, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.
