Photo Album: Attic insulation in Les Cedres, Qc

The problem Mrs. Hanley had an attic that wasn't well insulated. There were less than 10 in. of cellulose fibers in his attic which was equivalent to an R-38 value. The air circulation was almost non-existent which made the attic very humid. The solution - Seal air leaks on the attic floor such as joints and holes with our polyurethane foam - Add ventilation mats to improve the air circulation - Blow a little over 16” of cellulose fibers.

Overview of the attic before work

The attic did not have enough insulation and it was less than 10 in. of cellulose. In addition, it did not have good air circulation which is very important to avoid humidity in the area.

Lack of insulation

There was less than 10 in. of cellulose in the attic. This equates to an R-38 value. A poorly insulated attic will make the house less comfortable and will increase energy costs.

Seal air leaks

One of the first steps when we insulate an attic is to seal the joints and holes that are sources of air leaks because they allow the heated air to escape more quickly into the attic. This increases energy costs and makes the house less comfortable.
