Some more air leaks were uncovered and sealed. the improvement was difficult to measure but perhaps the house leaks about 30 cfm less after all of the recent work. the photos below show two different areas of the living area that were excavated and then sealed with prosoco air dam.
the picture on the west wall shows a quarter inch hole to the right of the excavated area that was used to assess the quantity of air coming from the volume defined by the framing under the hole.
all of the areas excavated were determined to be leaky from thermal images.
