Wise Home Energy performed an initial Blower Door Test which showed an airflow of 4246 CFM (Cubic Feet per Minute) of air moving past the blower door.
Here are some of the steps Wise Home Energy took to correct this home’s problems:
- Insulated rimjoists
- Insulated walls and attic
- Targeted airsealing
And here is the result of the Blower Door Test taken after the air-sealing and insulation work was completed. The results show a CFM (Cubic Feet per Minute) of 2478, a reduction of 1768 CFM, or 43%. This resulted in a more comfortable home, lower energy bills, and a happier homeowner.
