The problem
Mr. Zerczy had only 5 to 10 inches of fiberglass insulation in his attic. The lack of insulation made his house very uncomfortable and he had noticed that the energy costs were getting very high.
The solution:
Remove the fiberglass insulation in order to seal all air leaks on the attic floor such as joints, holes, and recessed. Install vents all along the soffits to ensure good ventilation of the attic and prevent air from coming into contact with the insulation and then blow a little more than 16 in cellulose fibers to obtain an R-60 value.
