This Troy,IL home came to Dr. Energy Saver wanting a more comfortable master bath and an improved indoor air quality. To make the master bath more comfortable the cantilever was air sealed with spray foam to seal any air penetrations and to give it some insulation. The attic was air sealed with spray foam as well to seal up any gaps, holes, and more. Can lights were air sealed by putting a cover over them and then air sealing with spray foam. The vertical knee wall was sprayed with 2 part spray foam to give it the insulation it needed as well as sealing any air penetrations there were.
