Blower Door Test in Rockaway township, NJ

How Is A Blower Door Test Conducted?

When blower door test in Rockaway township, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.
