Blower Door Test in Edgewater Park, NJ

How Is A Blower Door Test Conducted?

In blower door test in Edgewater Park, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

How To Pass A Blower Door Test:

• Anticipate potential air leaks before testing begins.
• Use materials like Tyvek or Zip Sheathing as your air barrier and ensure every seam is well taped for best results.
• Use insulation with the right R-value and confirm it is properly installed throughout the 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.
• Local authorities often publish checklists to confirm compliance — get the Philadelphia example here.
• Using thermal imaging technology along with caulk and spray foam, Local Energy Audits identifies and seals leaks during the inspection./li>
