Attic Insulation Case Studies: Uninsulated Attic in Pointe-Clairem ,Qc

Challenge

During winter, ice dams and huge icicles got formed on the roof of Mrs. Forget's house. A lack of insulation in the attic was the cause of this problem. Mrs. Forget had even re-insulated her attic a few years ago, but the same problem reappeared.

Solution

The solution

- Install baffles, seal air leaks and blow just over 16" of cellulose

We removed the fiberglass insulation that was in the attic to seal all air leaks (joints and holes) with expanded foam. Subsequently, we added deflectors to allow better ventilation of the attic. Finally, we blew a little more than 16'' of cellulose fibers to reach an R-60 value.
