Every week I get the same question on a quote: "Do I really need an insulated garage door? It's just a garage." After 9 years of replacing doors in Ottawa, Kanata, OrlΓ©ans, and Nepean β and seeing what happens to under-insulated doors after three or four winters β my answer is always the same. Yes, you do. And the right R-value matters more than most homeowners realize.
Here's the honest breakdown: what R-value means, what works in Ottawa's climate, and how to decide between R-16 and R-18+ for your specific garage.
