Challenge

Mr. Choudhry recently bought a house in POINTE-AUX-TREMBLES .Upon inspection, it was strongly recommended that the attic insulation needed to be changed as there was only 6” of fiberglass insulation.

With the climate of Quebec, 6 inches of insulation in an attic is far from enough to have a comfortable home and to keep the air heated during cold weather. Poor insulation also leads to higher heating and cooling costs.

Solution

Mr. Choudhry contacted Systèmes Éconergie for the insulation of his attic. Our insulation method is done in 3 main steps:

1. Removing the old insulation

2. Sealing all air leaks with polyurethane foam (joints, recesses, holes, etc.) By sealing air leaks, your house will keep the air you are heating longer during the winter and the cooler air in the summer.

3.Blowing a little over 16” of cellulose fibers. Cellulose is a very effective, safe and even ecological insulation!

With this complete solution, our client can have peace of mind and have a comfortable home.

Project Summary

City: POINTE-AUX-TREMBLES

Problem: A poorly insulated attic

Solution: Cellulose fibers

Recessed lights are a source of air leakage because of the hole there. As the insulation cannot be on the electrical box of the recessed for safety measures, we put a box and seal it with our polyurethane foam

Vents are essential for proper air circulation in the attic. They help ventilate the attic and prevent high humidity.

Our foremen always use this rule in order to blow the right amount of cellulose also into the attic. 16 -0 of cellulose will be blown to reach an R60 value. It would take at least 22" of fiberglass to achieve the same R60 value. So cellulose is much more effective.
