Blower Door Test in Burlington township, NJ

How Is A Blower Door Test Conducted?

To perform blower door test in Burlington township, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?

Construction in Burlington township, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance.

How To Pass A Blower Door Test:

• Anticipate potential air leaks before testing begins.
• Install an effective air barrier, for example Tyvek or Zip Sheathing, and make certain all seams are sealed with durable tape.
• Use properly rated insulation with the right R-value and ensure consistent coverage 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.
• Seal every transition point between conditioned and unconditioned environments, including attics, crawl spaces, and basements.
• Many local municipalities issue code compliance checklists — the Philadelphia example is available here.
• Local Energy Audits uses professional-grade thermal imaging, caulk, and spray foam to locate and close leaks during the visit./li>
