Attic insulation in Mascouche
In Mascouche, 49.6% of homes were built since 2001, on land settled as early as 1717. Isolation Cornerstone visits those attics for free, old or new, then sends a written quote.
Saint-Henri-de-Mascouche, until 1971
The area was first called Saint-Henri-de-Mascouche, after a parish founded in 1749, and only became Mascouche in 1971. Settlement had followed the Mascouche River, which still runs through the town centre. The houses belong to a different era: 23.5% date from 1961 to 1980, 22% from 1981 to 2000, and only 4.9% from before 1961.
In the older ones, we often find yellowed batts, thin and packed down between the joists. The newer ones raise their own question: an attic can be filled with insulation without reaching R-50 everywhere.

Reading the depth yourself
That is what the depth rulers set in the insulation are for: after the blowing, you read the thickness yourself. We blow in R-51 at minimum, up to R-60 when the height under the roof allows, from wall to wall. In a city where 76.2% of households own their home, that is a number you read yourself. The method is explained on the attic insulation page.

Hi! Pick a question and we’ll answer right here.
Choose a question
- In a newer Mascouche neighbourhood, how can I tell whether the soffits are clear?
- A clear soffit lets air enter under the roof. A block of wood plugging one is removed, and a baffle goes in at every soffit before the insulation is blown.
- 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.
