Blower Door Test in Ship Bottom borough, NJ

How Is A Blower Door Test Conducted?

When blower door test in Ship Bottom borough, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. 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 air is pulled from the home, outside air finds its way in through cracks and unsealed openings. 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?

Construction in Ship Bottom borough, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities.

How To Pass A Blower Door Test:

• Anticipate potential air leaks before testing begins.
• Select a proper air barrier such as Tyvek or Zip Sheathing and ensure every seam is thoroughly taped for airtight sealing.
• Use insulation of the correct R-value and confirm that it’s tightly installed throughout every section of 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 all joints and gaps that connect conditioned and unconditioned areas such as basements, attics, and crawl spaces.
• Many local building offices offer a step-by-step checklist to confirm compliance — view the Philadelphia sample here.
