Blower Door Test in Kinnelon, NJ

How Is A Blower Door Test Conducted?

When blower door test in Kinnelon, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.
