Spray Foam Insulation in Scarborough, 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
Back-splits and side-splits across Scarborough have knee walls and short roof sections that are almost impossible to insulate properly with batts. Foam follows those shapes, which is why it is usually the right call on this housing type.

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.
