Spray Foam Insulation in Mississauga, Ontario
Closed-cell and open-cell polyurethane foam that air-seals and insulates in a single application — the highest R-value per inch available for GTA homes and commercial buildings.
The local picture
Mississauga's 1970s and 80s subdivisions leak most at the rim joists and around the cantilevered sections builders favoured in that era. Closed-cell foam is the practical fix there because it seals the joint and insulates it in the same application.

Typical ranges
Open-cell and closed-cell foam are priced differently and suit different assemblies. Here are the market ranges, what drives them, and why the right answer depends on the space rather than the price list.

Is spray foam safe once cured?
Once fully cured and ventilated, the foam is inert. We follow the manufacturer's re-occupancy times and tell you exactly how long to stay out of the treated area.
Closed-cell or open-cell — which do I need?
It depends on the assembly, the space available and your budget. We recommend one over the other after seeing the site, not before.
Can it be applied over existing insulation?
Usually not. Foam needs to bond to a clean substrate, so old batts or blown-in material generally come out first.
