Blower Door Test in Tabernacle township, NJ

How Is A Blower Door Test Conducted?

When performing blower door test in Tabernacle township, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. 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.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?
