What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Sayreville, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.
