A building's insulation is only as good as the product going into the building and the crew putting it there. Isolation Majeau has been improving buildings across the Greater Montreal Region for decades; that level of experience comes only by installing quality products.
For most homeowners, you don't think about or see your insulation once the attic is closed..and once the drywall is up, it's difficult to replace or repair! Choosing a professional insulation company that installs quality products matters for the entire life of the building. That's why Isolation Majeau installs products from established, industry-leading manufacturers, every one of them backed by the manufacturer's warranty.
Isolation Majeau doesn't chase the cheapest product available. We work with manufacturers that have a proven track record in Quebec's climate, that meet or exceed Quebec building code, and that carry the certifications to back up their performance claims.
Our professional teams also carefully trial and test products before adding them to our products list. Our parent company is one of Canada's largest insulation purchasers, and works closely with manufacturers to not only install the best insulation products in Canada, but even help develop new versions of them.

BASF Canada has been producing spray foam insulation for the Canadian market for decades and understands the demands of our climate. Their WALLTITE line is a medium-density, closed-cell spray foam that insulates and air seals in one step. The current generation uses HFO blowing agents, which lowers the product's global warming potential compared to older formulas.
Spray foam insulation has improved greatly in the last few decades - it's more efficient to install, has cold weather variants for year-round installation, and a much lower environmental impact compared to spray foam in the 1990's or earlier.
This is our dependable, high-performance choice for residential, commercial, and industrial work.
Based in Quebec since 1977, Igloo Cellulose has grown from a local manufacturer into a name recognized well beyond our borders. We consider their cellulose among the best available, with an R-value of 3.7 per inch and a formula suited to the cold-climate assemblies we work in every day. Cellulose fibre works well in walls, roofs, floors, ceilings, and other enclosed spaces, and it's a product we're confident putting into a Quebec home.
Isolation Majeau specializes in using our industry expertise to choose the right product for the job. A rim joist, attic floor, and a dividing wall between units all call for different materials. When we assess your project, we'll recommend the material that fits the application, the budget, and the performance you're after - and we'll explain why!
