Spray Foam Insulation in Brampton, 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

Bonus rooms over garages are the single most common spray foam job in Brampton — that floor sits over unheated space and was rarely sealed properly. Foam applied to the garage ceiling is usually what finally makes the room usable in winter.

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.

Questions about this service

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.

Insulate smarter. Save energy. Live better.
