What to know about Spray foam insulation
Spray polyurethane foam is mixed on site from two liquid components and sprayed onto rim joists, foundation walls, roof decks and framed walls, where it expands and hardens in place. Because it fills every crack and joint it touches, it does two jobs at once: it insulates, and it stops air from leaking through the assembly. That makes it especially useful in the awkward, leaky parts of a Canadian house where batts or boards are hard to fit well.

How to choose spray foam contractors in Sainte-Catherine
- Choose a contractor who talks about air sealing and ventilation, not only adding more insulation.
- Ask them to check the attic or walls for moisture, mould, old wiring or insulation that may contain asbestos before starting.
- Get a written quote that states the type of insulation, the areas covered and the target insulation level.
- For spray foam, ask about their training, curing time and when it's safe to be back in the home.
- Consider an energy audit before and after the work to see where heat is being lost.
