Blower Door Test in Wyckoff, NJ

How Is A Blower Door Test Conducted?

When conducting blower door test in Wyckoff, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. 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.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

Properties in Wyckoff, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Meeting this benchmark in your blower door test in Wyckoff, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

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.
• Use insulation featuring the proper R-value and verify complete, gap-free coverage across 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.
• Make sure to seal all separations between conditioned and unconditioned areas, including crawl spaces, basements, and attics.
• Most building departments provide detailed compliance resources — view the Philadelphia checklist example here.
