A duct that stops in the attic

The biggest block of Boisbriand homes, 43.5%, dates from 1981 to 2000. A bathroom fan, range hood or dryer duct that ends in the attic dumps warm, damp air there.

That air rises toward the roof. Vapour condenses on the roof deck and mold sets in on the wood. So the ducts are routed outside before any insulation goes in, with the ceiling air leaks sealed and a baffle at every soffite. The details are on our attic mold removal page.

From a 1683 fief to a town in 1970

In 1683, Michel-Sidrac Dugué de Boisbriant was granted a fief north of the Mille Îles River. In the 20th century, the municipality of Sainte-Thérèse-Ouest, founded in 1946, became a town in 1970 and took the name Boisbriand in 1974. From 1961 to 1980, 30.8% of its homes went up, and those attics are now more than forty-five years old.

Isolation CornerstoneAnswers from the team

Hi! Pick a question and we’ll answer right here.

Choose a question

I live in a semi-detached house in Boisbriand: does LogisVert apply to me?
Yes, if the house is heated mainly with electricity: the measure is aimed at single-family, semi-detached and row houses. The roof has to reach R-50 over its whole surface, the insulation is done together with the caulking, and Hydro-Québec decides.
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.
