Systèmes Éconergie Case Studies: A poorly insulated attic in Pointe-Claire, Qc
Mrs. Eaves contacted Systèmes Éconergie because she had problems with an ice dam on the roof of her house in winter. Ice dams form because the attic is insufficiently insulated and ventilated. An ice dam is a ridge of ice that forms along a roof’s edge. It prevents melted snow from draining off the roof, causing the snowmelt to back up and damage the roof.
Actually, in the attic of her house, there were only 10 inches of fiberglass insulation, which was far from enough.
To improve the comfort of her home as well as eliminate ice dams, we removed the old insulation and sealed all the air leaks present on the attic floor with our expanded polyurethane foam. And then we blew just over 16” of cellulose fibers to achieve an R-60 value.
