Blower Door Test in Spring Lake Heights, NJ

How Is A Blower Door Test Conducted?

When blower door test in Spring Lake Heights, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. 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 drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.
