Systèmes Éconergie Case Studies: Problems with ice damns in an attic in Laval, Qc
Mr. Tang contacted Systèmes Éconergie to re-insulate his attic because he had problems with an ice dam on his roof in winter.
He also felt breezes of cool air in the rooms upstairs. This was due to poor insulation in his attic. He only had 6” of fiberglass insulation in his attic. Which is not sufficient for good insulation here.
