Sidewalls and Air Tightness Experiment

Tomorrow we will begin a training / experiment on what effect dense-packing sidewalls has on air leakage. We will run a pre-blower door, a blower door once the upper walls have been completed and then a final blower door once the lower level walls are done.

The home is a 1952 colonial style, approximately 2000 square feet. The attic has been air sealed and cellulose blown to an R40. The basement has had the addition crawl insulated, and the main portion has had the band joist stuffed and foamed. The exterior is vinyl sided; the interior is drywalled.

This past winter was frigid - however the gas bills during the heating season averaged $150 - proving the attic is the "place to be."

Over the next few days we'll check in with the blower door readings...
