The problem: This client from Pointe-Claire in Montréal, had a problem with his house. He found his rooms upstairs not comfortable. They were hot during the summer, even with the air climatization on and during the winter his rooms were not comfortable as he wanted them to be.
The solution: We replace the old isolation with a brand new one. We use blown cellulose for those types of projects. We blow over 16 inches to achieve R60 of value.
