Blower Door Test in Somers Point, NJ

How Is A Blower Door Test Conducted?

To execute blower door test in Somers Point, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

What Is A Passing Blower Door Test Score?

In Somers Point, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Achieving this standard in your blower door test in Somers Point, NJ lowers utility bills and guarantees adherence to local code requirements.

How To Pass A Blower Door Test:

• Anticipate potential air leaks before testing begins.
• Choose Tyvek or Zip Sheathing as your air barrier and check that all seams are securely taped to maintain airtightness.
• Use insulation that has the designated R-value and confirm it’s properly applied throughout the building envelope for maximum efficiency.
• 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.
