Blower Door Test in South Plainfield borough, NJ

How Is A Blower Door Test Conducted?

To carry out blower door test in South Plainfield borough, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.
