Blower Door Test in Bass River township, NJ

How Is A Blower Door Test Conducted?

To perform blower door test in Bass River township, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal 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.

What Is A Passing Blower Door Test Score?
