The attic insulation of Mrs. Negret's house was insufficient. There was less than 10” of fiberglass mat in some places. This caused ice dams on her roof in winter and made her house uncomfortable.
We have sealed all air leaks such as joints, electrical wire holes. Then, we isolated the recessed lights by adding a box to each of them and sealing around the box. We insulated the access hatch with SilverGlo and finally blew out just over 16” of cellulose fibers.
