Spray Polyurethane Foam
We use Boréal Nature Élite spray foam from Genyk, ideal for insulating foundations (basements or crawl spaces), exterior or interior walls (brick, wood, or concrete), and attics.
This foam expands significantly and hardens on contact, sealing all air leaks and keeping moisture out. The result is total airtightness.
Polyurethane offers unmatched protection against harsh winters. It is the most efficient insulation available, with an R-value of 6 to 7 per inch of hardened foam. It is extremely durable, retaining its performance without shifting, settling, or crumbling over time.
You’ll reduce heating and cooling costs substantially, while also improving indoor air quality by minimizing allergens. This foam even increases the structural strength of your building by up to 3 times.
Blown Cellulose
Our cellulose insulation is made from recycled paper fibers and treated minerals, making it resistant to fire and mold. Once blown in, it expands and fills even the smallest gaps, forming an airtight barrier that blocks cold air and keeps warm air inside. It also provides excellent soundproofing.
With an R-value of 3.7 per inch, cellulose is used for insulating interior and exterior walls, ceilings, and attics.
Professional Insulation Equipment
Our experienced team uses high-performance tools to ensure a precise and even application. We work with the Graco Reactor professional dosing machine to apply spray foam consistently and accurately.
We have the technical expertise to deliver high-quality insulation down to the last centimeter.
