Attic insulation in Longueuil
In Longueuil, 39% of homes were built between 1961 and 1980, so their attics are now more than forty years old. Isolation Cornerstone makes a free visit, then sends a written quote, with no pressure.
Three boroughs, one dominant decade
Longueuil has three boroughs: Vieux-Longueuil, Saint-Hubert and Greenfield Park. The present city dates from the 2002 merger of eight South Shore towns; four of them regained their independence in 2006, including Brossard and Boucherville, and the former town of LeMoyne was folded into Vieux-Longueuil.
Across the city, the dominant decade is the 1970s: according to Wikipedia, 32% of the dwellings were built then, and the 2021 census counts 39% of homes from 1961 to 1980, against 16.3% from before 1961. Under the roof of those houses we may find yellowed batts, thin and packed down between the joists. Blown-in fibreglass at R-51 minimum makes an even layer from wall to wall.

More than half of households live in apartments
In 2021, 53.4% of Longueuil households lived in an apartment and 31.9% in a single-detached house. For a house heated mainly with electricity, Hydro-Québec’s LogisVert measure is aimed at the roof, provided insulation and caulking are done together, which Isolation Cornerstone does in a single project. Condos, multiplexes and apartment buildings do not qualify, and Hydro-Québec decides on eligibility. The details are on the LogisVert rebate page.

Hi! Pick a question and we’ll answer right here.
Choose a question
- I live in a duplex in Longueuil. Do I qualify for LogisVert?
- No. A duplex is a multiplex, and LogisVert covers none of them. The free visit and the written quote from Isolation Cornerstone remain available; Hydro-Québec decides on LogisVert.
- My Saint-Hubert bungalow has a low attic. Can blown-in fibreglass reach everywhere?
- Yes. Blown-in fibreglass reaches the corners where nobody can squeeze in, and settles into an even layer from wall to wall.
- Blown-in fibreglass or batts: which is better in the attic?
- Blown-in fibreglass, at Isolation Cornerstone. It reaches the corners nobody can crawl into and forms an even layer from wall to wall, at R-51 minimum, with depth rulers left standing in it so you can read the depth yourself.
- How long does the work take?
- The exact time is given with the quote, once the attic has been seen. On the day of the work, the house is protected with tarps and cleaned before the crew leaves.
