Blower Door Test in Laurel Springs borough, NJ

How Is A Blower Door Test Conducted?

To complete blower door test in Laurel Springs borough, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.
