Mrs. Hanley had an attic that wasn't enough insulated. There were less than 10 in. of cellulose fibers in her attic which was equivalent to an R-38 value. The air circulation was almost non-existent which made the attic very humid.
Remove the cellulose, seal air leaks on the attic floor such as seams and holes with our polyurethane foam, add ventilation mats to improve air circulation, and then blow a little over 16" of cellulose fibers.
