With Ottawa temperature swings from -35°C to +35°C, insulation isn't a luxury — it's a necessity. Here's how to choose the right insulated door for your Ottawa home.
Why Insulation Matters in Ottawa
An uninsulated garage door has an R-value of about R-2. Ottawa's climate requires at least R18 to maintain a reasonable temperature in an attached garage. Better insulation means lower heating bills, less noise, and a more comfortable home.
Understanding R-Values
R-value measures thermal resistance. For Ottawa we recommend R18 insulation: it keeps your garage 10–15°C warmer, reduces heating costs, and is ideal for both attached and detached garages, especially if you use the space as a workshop or want maximum comfort.
Top Pick: Garaga Standard+ (R18)
Garaga is a Quebec-based manufacturer that designs specifically for Canadian winters. The Standard+ line offers R18 insulation, steel construction, and is available in dozens of finishes. Price installed: $1,800–$2,800 depending on size and style.
Best Value: Clopay Coachman (R18)
Clopay's Coachman series offers R18 insulation with a realistic wood look at a fraction of the price of real wood. Durable, low-maintenance, and well-suited to Ottawa's freeze-thaw cycles. Price installed: $1,400–$2,200.
Premium Option: Garaga Prestige (R18)
For homeowners who use their garage year-round, the Garaga Prestige series offers R18 insulation with a premium finish and 10-year warranty. Price installed: $2,600–$4,200.
What to Avoid
Single-layer steel doors with no insulation are false economy in Ottawa — the energy costs alone will exceed the savings within 3–4 years. Also avoid polystyrene-only insulation; polyurethane-injected doors outperform them significantly.
