The problem: This client from Brossard had an attic that was not insulated well. It had old fiberglass and it wasn't optimal for this attic. Also, the client was feeling that his rooms upstairs were not comfortable. During winter they were cold and in the summer they were really hot. Something not right was happening in this attic.
The solution: We remove all the old isolation, after this, we seal off all cracks that happen to leaks air with expandable foam. After, we blown over 16 inches of cellulose to achieve R60 of value.
