How Is A Blower Door Test Conducted?

When blower door test in Fort Lee borough, 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 sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.
