Blower Door Test in Pittsgrove, NJ

How Is A Blower Door Test Conducted?

For blower door test in Pittsgrove, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. 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 exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. 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?

How To Pass A Blower Door Test:

• Anticipate potential air leaks before testing begins.
• Apply an appropriate air barrier, such as Tyvek or Zip Sheathing, making sure every seam is correctly taped for maximum performance.
• Ensure the insulation used meets the proper R-value and is well fitted throughout the structure’s building envelope.
• Seal all penetrations in exterior walls using caulk or spray foam.
• Ensure doors and windows are properly installed, caulked, and weather-sealed.
• Close any gaps connecting conditioned and unconditioned spaces, such as those leading to basements, attics, or crawl spaces.
