How Is A Blower Door Test Conducted?
When blower door test in Wyoming, DE 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 used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.
As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in DE conditions.
