Blower Door Test in Manalapan, NJ

How Is A Blower Door Test Conducted?

When conducting blower door test in Manalapan, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

In Manalapan, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. Passing this threshold during your blower door test in Manalapan, NJ ensures both energy savings and full compliance with local regulations.

How To Pass A Blower Door Test:

• Anticipate potential air leaks before testing begins.
• Use high-quality air barrier materials like Tyvek or Zip Sheathing and confirm all seams are perfectly 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.
• Seal the transitions between conditioned and unconditioned zones, particularly around basements, attics, and crawl spaces.
• Local code offices often issue compliance checklists — access the Philadelphia example here for reference.
• Local Energy Audits is equipped with thermal imaging tools, caulk, and spray foam to find and seal air leaks immediately on-site./li>
