Thinking of Your Home’s Insulation?
If you think you’re among the 80% of Canadian homes that are under-insulated,[i] performing a simple insulation inspection will help you determine your insulation needs. Having the correct amount of attic insulation can help you maintain a comfortable temperature throughout your home and help save money on your energy bills[ii]. Plus, it can prevent major issues like ice dams in the winter.
Inspecting Your Attic Insulation
First thing’s first, you need to go up into your attic, inspect the condition of the insulation, and calculate the current level of insulation. Your attic should have a certain amount of insulation in it, and the recommended level of insulation for your attic is dependent on where you live.
If your insulation doesn’t measure up and you need more, installation can be done as a weekend DIY project or you can call a professional installer to handle the job.

How Much Insulation Should You Install?
NAIMA Canada recommends bringing the insulation level to above current energy efficiency code levels. Codes are updated every few years, and you don’t want to keep re-insulating to keep up with code. The amount of insulation recommended for your home will vary depending on a number of factors:
Where you live—Different climates require different insulation R-values. You will need a higher R-value of insulation if you live in the north than if you live closer to the US border.
Your home’s age—If your home is more than 10 years old, you likely need more insulation. There are many ways to retrofit a home with fiberglass, rock wool, or slag wool insulation.
Recommended Levels of Insulation
