Home Insulation

Why home insulation matters

Heating and cooling energy costs for a Quebec home can be one of the largest ongoing monthly expenses, and a poorly insulated house loses energy constantly. Heat escapes through the attic, walls, basement, and gaps around the building envelope, which means your furnace and air conditioner have to work harder and run longer to hold a comfortable temperature. According to Natural Resources Canada, air leakage alone can account for 20-30% of heat lost from an older home, and can cost $1,000 or more extra in heating costs per year.

If your home has rooms that never seem to hold a constant temperature, cold floors above unheated spaces, drafts near baseboards and outlets, inconsistent temperatures between floors, or heating and cooling bills that keep climbing, it's probably time to get a free quote from the experts at Isolation Majeau!

Where Insulation Makes the Biggest Difference

Every home is different, but the areas that Isolation Majeau sees our customers get the best return are:

1. Attic and roof insulation, since heat rises and an under-insulated attic is usually the single largest source of energy loss.
2. Wall insulation, which covers the largest surface area of the home and has the biggest effect on day-to-day comfort.
3. Basement and foundation insulation, where below-grade concrete can pull heat out of the home and cause moisture problems.
4. A bonus that we see is often under-insulated in Quebec homes: basement rim joists! This area of the basement is above-grade, and a huge source of a home's heat loss.
