Attic insulation in Saint-Hyacinthe
Nearly one home in four in Saint-Hyacinthe dates from before 1961, and it takes a trip up to the attic to see what more than sixty years of seasons have done to the insulation. Isolation Cornerstone makes that visit for free, then sends a written quote.
Under the roof of a pre-1961 house
In an attic of that age we often find old yellowed batts, thin and packed down between the joists. Heat then passes straight through. The job follows a set order: ceiling air leaks sealed first, roof ventilation cleared, insulation blown in last.
With another 32% of homes built from 1961 to 1980, more than half of the housing stock is over forty-five years old.
- 23.7% Before 1961
- 32% 1961 to 1980
- 23.6% 1981 to 2000
- 20.6% Since 2001

Six towns that became one, on both sides of the Yamaska
The Yamaska runs through the city from south to north. Saint-Hyacinthe absorbed La Providence, Saint-Joseph and Douville in 1976, then on December 27, 2001, six towns were grouped together, including Sainte-Rosalie and Saint-Thomas-d’Aquin. Houses in the centre and in the former villages do not share one history: each attic has its own story.
Only 48.6% of households own their home, and 8.3% of dwellings are duplexes. LogisVert is meant for houses only; a duplex or an apartment building does not qualify.

Hi! Pick a question and we’ll answer right here.
Choose a question
- I saw silvery-gold granules in my attic. Can we insulate over them rather than remove them?
- No. Isolation Cornerstone never reinsulates over vermiculite, because it can contain asbestos, according to Health Canada. Do not touch it, do not climb up to check, and describe what you saw to Isolation Cornerstone: if that is what it is, it comes out first, safely.
- 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.
- 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.
