Blower Door Test in New Providence borough, NJ

How Is A Blower Door Test Conducted?

To perform blower door test in New Providence borough, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

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. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

In New Providence borough, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Achieving this goal during your blower door test in New Providence borough, NJ promotes energy savings and demonstrates adherence to local building rules.

How To Pass A Blower Door Test:

• Anticipate potential air leaks before testing begins.
• Employ an appropriate air barrier system such as Tyvek or Zip Sheathing and verify that each seam has been correctly taped.
• Place insulation with the accurate R-value and check for proper installation and full coverage in 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.
• Ensure all penetrations between conditioned and unconditioned areas—like attics, basements, and crawl spaces—are tightly sealed.
• Many building departments provide step-by-step compliance guides — you can find the Philadelphia example here.
• Local Energy Audits uses thermal imaging tools, caulk, and spray foam to detect and seal leaks directly on-site./li>
