Systèmes Éconergie Case Studies: Poor attic insulation and insulating it in Dollard-des-ormeaux, Qc
Proper attic insulation is the best way to prevent heat loss in the winter and retain cool air in the summer. So it's time to pay close attention to what's happening up there.
Mr. Grushka had high heating and cooling costs. His house has become less comfortable. He contacted Systèmes Éconergie to review the insulation of his attic.
The solution was to re-insulate the attic and make the attic more airtight. To do this, our team removed the old fiberglass insulation to seal all air leaks such as the joints between the boards and the chimney and then the holes. Then we blew 16” of cellulose fibers for a thermal value of R60.
City: Dollard-des-ormeaux, Qc
Problem: High heating and cooling costs
Solution: Cellulose fibers
The attic was insulated with fiberglass. The problem is that fiberglass will not protect from mold growth.
The attic did not have ventilation mats and these are very important to have as they allow air circulation in the attic and reduce humidity.
Cellulose fibers blown here are very effective as insulation and are also also very safe.
