Blower Door Test in Brooklawn borough, NJ

How Is A Blower Door Test Conducted?

When blower door test in Brooklawn borough, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.
