Cost of Spray Foam Insulation In Toronto Ontario Canada

Spray foam insulation is a great way to seal your home to reduce air leaks and save on heating and cooling costs. There are 2 main types of spray foam insulation available for residential use: open-cell and closed-cell. Regardless of which type you’re considering, cost is bound to be a factor. If you’re interested in spray foam insulation for your home, look into the cost of spray foam insulation in Ontario, Canada before you call a contractor.


Open cell spray foam has a density of roughly 1/2 lb. per cu. ft. It has an R-value of R-3.5 to R-3.6 per inch. The R value depends on the density of the foam and like with other types of insulation, the higher the density, the higher the R value. The R value of the foam plays a role in how well your home is insulated against heat flow. Having more resistance is better as it prevents warm air from moving out.

Open-cell spray foam is usually applied to the walls, roof and ceiling. It is not as vapour resistant and when applied to the attic, it is advised that the paint is sprayed with some sort of vapour-retardant paint.

Costs vary depending on the installer, but are usually between $2 and $7 per square foot.


Closed cell spray foam has a density of 2 pounds per cubic foot. It has an R-value of roughly R-6.5 per inch. It can be applied to walls, roofs, ceilings and slabs. The quality of the foam is higher, giving better results than any other form of insulation. It also creates a very good air and moisture barrier, which makes it ideal for use in old homes. Closed cell insulation can also add to the strength of the structure, making it particularly attractive during remodeling projects. Some contractors don’t like to use closed cell spray foam insulation as it requires the use of blowing agents that contribute to global warming.

Costs vary, but typically fall in the range of $1.75 to $3 per square foot.

Like any investment, the initial installation of spray foam will be costly, but the investment will pay for itself over time in the form of reduced heating and cooling bills. As a bonus, you’ll enjoy a more comfortable home environment while the insulation protects against drafts, moisture and other nuisances.
