Blower Door Test in Seaside Heights borough, NJ

How Is A Blower Door Test Conducted?

To perform blower door test in Seaside Heights borough, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

In Seaside Heights borough, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance.

How To Pass A Blower Door Test:

• Anticipate potential air leaks before testing begins.
• Choose an appropriate air barrier, like Tyvek or Zip Sheathing, and ensure all seams are accurately and securely taped.
• Use insulation with the right R-value and confirm it is properly installed 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.
• 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 is equipped with thermal imaging tools, caulk, and spray foam to find and seal air leaks immediately on-site./li>
