Air leaks in your attic will cause substantial heat loss and lead to a variety of moisture-related problems in your home.
What to Look For
- Insulation is rated by its R-value. “R” stands for resistance and the higher the R-value, the more efficiently it resists the transfer of heat from one area to another.
- Different types of insulation have different R-values, but you can combine them to achieve a higher overall rating.
- The recommended R-value for attic insulation in Ontario is between R-50 to R-60.
- The most common types of insulation used in attics are spray form, loose-fill, and batt and blanket insulation.
Things to Consider
- Ensure your project meets the minimum R-Value needed to receive available rebates.
- Hire a professional. Improper installation can lower the R-value of the material, and there are health and safety measures that must be considered.
- Consider the City of Toronto’s Home Energy Loan Program (HELP) as a way to finance your purchase of insulation.
- Before you purchase new insulation, get an EnerGuide home evaluation and check with your municipality, utility or retailer to see if rebates are available.
