Attic insulation

Most Ontario homes are significantly under-insulated relative to current building code — here's what that costs you, and what proper insulation fixes.

90%

of Canadian homes are estimated to be insufficiently insulated.

40%

of a home's heat loss is related to poor attic insulation.

20–30%

in monthly heating and cooling savings when insulated properly.

R-60

the provincial minimum for attic insulation since January 1, 2017 — about 22.25 inches.

It is estimated that 90% of homes in Canada are not insulated sufficiently. Experts have stated that up to 40% of a home's heat loss is related to poor attic insulation — when insulated properly, a homeowner can save between 20 and 30% on monthly heating and cooling bills.

As of January 1, 2017, the provincial government mandated a minimum value of R-60 for attic insulation — approximately 22.25 inches. The previous building code equated to 18 inches, and before that, 12 inches.

In most 15- to 20-year-old homes, the 12 inches of insulation originally installed has settled to approximately 9 to 10 inches — significantly short of the 22.25 inches required to meet today's building standards, which costs you 20 to 30% extra on your monthly heating and cooling bills.

We install pink fibreglass blown-in insulation by Owens Corning to bring your attic back up to code.
