Blower Door Test in Folsom, NJ

How Is A Blower Door Test Conducted?

To carry out blower door test in Folsom, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. 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?

In Folsom, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Meeting this benchmark in your blower door test in Folsom, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Why Do I Need A Blower Door Test?

How To Pass A Blower Door Test:

• Anticipate potential air leaks before testing begins.
• Apply an air barrier like Tyvek or Zip Sheathing, making sure all connecting seams are properly taped and sealed.
• Apply insulation of the correct R-value and make sure it fits snugly in all areas 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.
• Close gaps and penetrations between conditioned zones and unconditioned sections like attics, basements, and crawl spaces.
• Many cities provide compliance checklists through their building departments — see the Philadelphia version here.
• Local Energy Audits identifies and repairs leaks on-site using thermal imaging tools, caulk, and high-quality spray foam./li>
