A well-insulated and properly ventilated attic will help you save on heating and cooling costs, while increasing the lifespan of your roofing!

For attic insulation in Drummondville, Sorel-Tracy or another city in the region, trust the team at TOITURES BERNIER. We have been providing attic insulation services for 25 years and are members of the Commission de la construction. We also hold a valid RBQ contractor license (no. 5660-9662-01).

Our team insulates attics using either cellulose fiber insulation (R-value of 3.7 per inch) or spray polyurethane (R-value of 6 per inch). Both types of insulation include fire-retardant and rodent-resistant properties.

Cellulose fiber is made from recycled materials (100% natural and eco-friendly). It is blown in under pressure to fill every corner of your attic (approximately 3.5 pounds per cubic foot). Cellulose insulation is very airtight and also provides excellent soundproofing.

Spray polyurethane foam also fills all cavities in your attic, then expands and hardens. It is the most high-performance insulation on the market, offering strong resistance to cold air infiltration and mold.

Please note that our technicians must inspect your attic before agreeing to perform insulation work.

Ask about the attic insulation grant available through the LogisVert program.

To prevent humid air from accumulating in your attic and avoid mold formation, it is essential to have a properly functioning roof vent and ensure that ventilation soffits (located near the roof edges) are not blocked by insulation. The shingle manufacturer’s warranty will not be valid if your roofing is not properly ventilated.

Our team can install or replace your roof vent and verify that your soffits are clear. Our technicians can also install Styrovents, which keep insulation away from the soffits.
