Homeowners in Sumerduck, VA had upstairs bedrooms and a top floor that was always too hot in the summer and too cold in the winter. They also wanted to minimize the infiltration of outside air in their basement. The Comfenergy production crew removed all of their existing insulation and air sealed all of the accessible penetrations and top plates. We then blew in TruSoft cellulose insulation and installed a metal chimney wrap with rockwool. We also dense packed the walls of the top floor by drilling through the drywall and inserting TruSoft cellulose. Finally, to reduce heat loss and cold air infiltration in the basement, we air sealed and insulated the rim joist area with spray foam.
