Blower Door Test in Clementon borough, NJ

How Is A Blower Door Test Conducted?

During blower door test in Clementon borough, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. 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.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.
