Photo Album: Attic insulation in Montréal, Qc

Problem: Lack of insulation in the attic. This makes the house less comfortable leading to higher electricity costs. Solution: Remove the old fiberglass insulation to seal the air leaks with our polyurethane foam and blow a little more than 16 in. of cellulose fibers to achieve an R60 value.

Old attic before renovation

Here is an overview of the attic before the work had started.

There was only 7

It's a very small amount to keep your home comfortable. It needs to be at least doubled.

Ventilation mats installed

Once the old insulation was removed, we installed ventilation mats in the attic soffits to improve air circulation and prevent any humidity.

Sealing the air leaks

Then we seal the air leaks like holes, joints, etc. with polyurethane foam.

Blowing our Cellulose fibers

Finally, we blow 16” of cellulose fibers to achieve R60, which is the best for your home comfort. Cellulose is safe, environmentally friendly and very effective.
