Customer was experiencing high utility bills, as well as a cold home in the winter and a hot home in the summer. The lack of insulation in the attic played a big role to the discomfort of the home. The attic initially had fiberglass insulation with an R-value of 8. We vacuumed out the existing fiberglass insulation, and sealed all top plates in the attic and the rim joists in the basement. We then blew in Cellulose insulation to an R-Value of 60 or 17 inches. We achieved a 46% air leakage reduction, which was only possible with the removal of the existing fiberglass insulation. Not only will this customer see a drastic drop in the utility bills, they will experience a much more comfortable home during the winter and summer months.
