Frequently Asked Questions

What R-value do I need in Canada?

Canadian building codes require high R-values due to cold winters. Typical requirements are R-50 to R-60 for attics, R-24 for walls, and R-31 for basement walls in most climate zones.

Does Canada use R-value or RSI?

Canada officially uses RSI (metric thermal resistance in m2 K/W), but R-values are commonly referenced in practice. Our calculator displays both systems for convenience.

What insulation is best for Canadian winters?

Spray foam and rigid foam boards are excellent for Canadian climates due to their high R-value per inch and air sealing properties. Blown-in cellulose and fiberglass batts are also popular and cost-effective options.
