Duvernay, Fabreville, Auteuil, Pont-Viau: every Laval neighbourhood has its streets of homes built in series, often with 6 inches of attic insulation and nothing more. Forty years later that insulation has settled and heat escapes through the roof. You can see it in the icicles and the patches of melting snow. These houses are all alike, and that's good news: our calculator gives you a precise price from the footprint of your home, without a rep ever setting foot in your house.
What we find in Laval attics
In the attics we insulate in Laval, the existing insulation measured 6.5 inches at the median before the work, or about R-18. Half of the attics measured were between R-17 and R-22. The target in Quebec is R-50, and we install R-51.
- R-18 found at the median
- +33 to add for R-51

Depth measured with a ruler by our installers in Laval attics, converted to an R-value for fiberglass. Old cellulose would come out about 15% higher.
What it means for a home in Laval
For a 800 sq ft attic, the median area we measure in Laval, going from R-18 to R-51 means estimated heating savings of about $160 a year, or about $3,200 over 20 years, for a home heated with electricity. How we estimate it
For 90% of the attics we insulated in Laval, we opened the LogisVert grant file with the client. The grant goes up to $1,500, and we handle the paperwork.
