Insulating walls to provide greater comfort in the home, greater energy savings and less expense on electricity bills and heating.

Isolating the walls of your home, if you live in Montreal or in a home built before 1980, it is a necessity, because they have very little insulation.

All the small holes allow an entry of air, that increases your energy bill every month.

So the return on investment is done rather quickly.

To isolate is to save.
