The problem
Ms. Smith contacted Systèmes Éconergie because she had problems with ice dams on her roof in winter. This very common problem is due to poor attic insulation and the presence of air leaks.
The solution
We removed the old wool insulation in order to seal the air leaks such as joints, holes and others. Then, we installed vents on each side of the attic to allow additional ventilation in the attic and prevent air from touching the insulation. Eventually, we blew just over 16” of cellulose fibers to achieve an R-60 value.
