Blower Door Test in Glassboro borough, NJ

How Is A Blower Door Test Conducted?

To perform blower door test in Glassboro borough, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

• Use an air barrier system such as Tyvek or Zip Sheathing and verify that each seam is properly sealed with tape.
• Ensure insulation with the specified R-value is properly installed and fitted throughout the entire building envelope.
• Seal all penetrations in exterior walls using caulk or spray foam.
• Ensure doors and windows are properly installed, caulked, and weather-sealed.
• Seal all joints and gaps that connect conditioned and unconditioned areas such as basements, attics, and crawl spaces.
