Three homes in four are houses
That is LogisVert territory. Hydro-Québec’s program targets houses heated mainly with electricity, and 75.9% of Lavaltrie households own their home. It asks for the roof insulation and the caulking to be done together, with at least R-50 over the whole roof surface. Isolation Cornerstone does both in the same project and blows in R-51 at minimum. Hydro-Québec decides who qualifies.

A seigneury of 1672, a town reunited in 2001

Houses from 1981 to 2000 are the most numerous: they are between twenty-five and forty-five years old; a packed-down layer lets heat through. The 33.6% of homes built since 2001 are worth checking with a ruler, since the layer can be uneven. The 17.5% from 1961 to 1980 come next, and only 7% predate 1961.

Hi! Pick a question and we’ll answer right here.
Choose a question
- My house in Lavaltrie dates from 1992. How can I read the insulation depth myself?
- With the depth rulers Isolation Cornerstone sets in the insulation: after the work, the thickness reads straight off the ruler, no tools needed. We blow in fibreglass to R-51 at minimum, from wall to wall.
- LogisVert vs. Rénoclimat: which one applies to attic insulation?
- LogisVert, from Hydro-Québec, covers roof insulation done together with caulking, in a house heated mainly with electricity. Rénoclimat, from the Québec government, requires an energy evaluation before and after the work, and can complement LogisVert when the work is separate. Each programme alone decides whether you qualify.
- 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.
