Blower Door Test in Monroe township (Camden), NJ

How Is A Blower Door Test Conducted?

For blower door test in Monroe township (Camden), NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

• 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 and seal every opening between heated or cooled spaces and unconditioned areas such as basements, attics, and crawl spaces.
• Local permitting offices often offer official compliance checklists — review the Philadelphia sample here for reference.
• With the help of thermal imaging tools, caulk, and spray foam, Local Energy Audits efficiently detects and seals leaks on-site./li>
