Roof insulation

Good insulation of the attic of your house is primarily intended to regulate the losses of warm air and reduce your energy consumption throughout the year.

Blown wool (cellulose) in combination with the installation of styrovents are used in most cases for roof insulation of your home. For optimal results in a house in Quebec's temperature though, the spray polyurethane foam application is unbeatable. Inform yourself prior to the insulation work in your attic, your cathedral ceiling or even for typical flat roofs. Learn more


Basement Insulation

Insulation of the foundation walls of your basement is useful against energy loss but serves also as a very effective protection. Sprayed urethane foam is a great sealant that prevents air infiltration as much as condensation, avoiding the formation of mold and excess moisture inside your walls. Learn more
