Insulation

Cut Your Heating Costs With High-Performance Insulation

Insufficient insulation translates directly into higher heating bills and reduced comfort. Les Entreprises JL installs blown-in insulation and eco-friendly cellulose in residential properties in Montréal and on the North Shore.

Blown-in insulation or cellulose: the right solution for your property.

Why Properly Insulate Your Property?

Heat loss through a poorly insulated ceiling or walls can account for up to 30% of your annual heating bill. In Québec, extreme temperature swings make residential insulation particularly critical. An upgrade is one of the highest-return investments you can make in the short term.
