Blower Door Test in South Bound Brook, NJ

How Is A Blower Door Test Conducted?

For blower door test in South Bound Brook, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In South Bound Brook, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes.
