Systèmes Sous-sol Québec Case Studies: Ice damming problem and bad attic insulation in Dollard-des-Ormeaux

Wednesday, November 28th, 2018 by Anastasie Najem


Mr. David in Montreal was referred to us September by an inspector who recommended him to contact us for a free estimate for attic insulation.  The customer had suffered ice damming problems last winter and needed to replace the old and inadequate insulation in the attic. We sent him our specialist Andrew who is excellent at inspecting attics and noticing where are the air leakages coming from. When discussing with the customer, Andrew discovered that there were 2 rooms that were always drafty and cold in the winter and too hot and humid in the summer. This is a very common sign of bad attic insulation. When he went into the attic, Andrew noticed that the opening door was not insulated. He also saw that the metal light box was letting air leaks in the attic. Can lights in the ceiling were letting air flow in through the housing and around the light bulbs. There was also a heating and cooling vent that was open and a vent box that wasn’t air sealed! Finally, since this attic has a cathedral ceiling, the insulating had to be done right in order to control the air flow to prevent further damage and ice damming.



To solve all of these issues, Andrew gave his recommendation and we sent our production team to do the job. As recommended, our team removed all the old insulation and debris and sealed all the joists, pipes, wire holes, duct chases and places where Andrew noticed air leakage. The opening door was insulated with our SilverGlo insulation panel. Our team also sealed the metal light box and covered the can lights with TiteShell can light covers. The vents were sealed and caped and the air flow was controlled. We finished by insulating the attic with blown cellulose which is much better than the pink fiberglass insulation. TruSoft cellulose insulation is made from recycled paper and is flame, mold and pest retardant. It is also denser than fiberglass and has a higher R-value. It fills all irregular gaps and voids and creates a seamless blanket.

We are glad to have done this attic insulation job and we are sure that our customer will notice a significant amelioration of his comfort and a decrease in energy bills.
