Blower Door Test in Island Heights, NJ

How Is A Blower Door Test Conducted?

During blower door test in Island Heights, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. 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 removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.
