Attic insulation in Châteauguay

Who LogisVert is aimed at
LogisVert is meant for houses: single-family, semi-detached, row, cottage or mobile home, heated mainly with electricity. Condos, multiplexes and apartment buildings are excluded. The measure targets roof insulation and caulking done together, and the roof has to reach at least R-50 over its whole surface. Isolation Cornerstone does both in one project, and Hydro-Québec decides on eligibility. Everything is explained on the LogisVert rebate page.
Between Lac Saint-Louis and the river, four bands of roofs
Châteauguay stretches from Lac Saint-Louis to the Châteauguay River, and its territory grew in stages: a merger with Châteauguay-Heights in 1968, the annexation of Châteauguay-Centre in 1975. The 2021 figures show four bands: 17.8% of homes from before 1961, 37.2% from 1961 to 1980, 21.4% from 1981 to 2000 and 23.6% since 2001.
The largest group, the 1960s and 70s houses, may have batts packed down by the years. The newest ones still deserve a check with a ruler.

Hi! Pick a question and we’ll answer right here.
Choose a question
- My Châteauguay house is heated with gas. Can the roof still be insulated?
- Yes. Roof insulation can be done whatever the heating; only the LogisVert measure requires mainly electric heating, and Hydro-Québec decides on eligibility.
- Is it better to blow new insulation over the old rather than strip it all out?
- Depends on what is underneath. A blocked soffit or warm air leaking through the ceiling would stay hidden under the new layer, so Isolation Cornerstone fixes those first, then blows. Vermiculite is never covered over: it comes out first.
- I think there is vermiculite in my attic. What should I do?
- Leave it alone, and don’t go up to check. Vermiculite can contain asbestos, according to Health Canada. Describe to Isolation Cornerstone what you saw, even from a distance: the crew comes to look at it, and it comes out before any insulation goes in.
