Looking for a garage door insulation kit in Canada? Finding the right kit at the right price can be tricky - some retailers have limited stock, others ship from the US with added duties, and prices vary by $30 or more for the same product. This guide breaks down exactly where to buy, what's in stock, and how to get the best deal at Canadian retailers in 2025.
The best place to buy a garage door insulation kit in Canada is Home Depot. They stock the Owens Corning R-8 kit ($89.99) and Reach Barrier reflective kit ($54.99) at most locations with same-day pickup available. For specialty products not found in stores, Amazon.ca has the widest selection with free Prime shipping on most kits.
Where to Buy: Retailer Breakdown
Home Depot Canada
Home Depot is the go-to destination for garage door insulation in Canada. They consistently stock the most popular kits at competitive prices, with the added convenience of in-store pickup and knowledgeable staff.
Products Available
- Owens Corning Garage Door Insulation Kit (R-8) $89.99
- Reach Barrier Reflective Insulation Kit $54.99
- Frost King Garage Door Insulation Kit $69.99
- Reflectix Reflective Insulation Roll (DIY) $34.99
Pro Tip: Check online inventory before visiting. Stock varies by location, especially for the Owens Corning kit which sells out during cold snaps.
Lowe's Canada
Lowe's carries a similar selection to Home Depot with occasional exclusive products. Their rewards program offers 5% back on purchases, making them slightly cheaper for frequent shoppers.
Products Available
- Cellofoam Garage Door Insulation Kit (R-10) $139.00
- Owens Corning Garage Door Kit (R-8) $89.99
- Thermwell Garage Door Kit $74.99
Note: Lowe's is the only major Canadian retailer stocking the Cellofoam R-10 kit in-store - the highest R-value option for our climate. For details on R-values, see our R-value guide.
Amazon.ca
Amazon.ca offers the largest selection including brands not available in Canadian stores. Watch for US imports that may have slower shipping or duty fees. Look for "Shipped from and sold by Amazon.ca" for best experience.
Products Available
- Meross Garage Door Insulation Kit $44.99
- Matador Garage Door Insulation Kit (Premium) $179.00
- US Energy Products 2-Car Kit $119.00
- SmartGARAGE Reflective Kit $54.99
Warning: Some listings ship from the US with duties. Check "Ships from" before ordering. "Fulfilled by Amazon" ensures fast, duty-free delivery.
Rona
Rona (now owned by Lowe's) has a smaller selection but occasionally offers clearance deals. Worth checking for sales, but don't count on specific products being in stock.
Products Available
- Rona-branded Reflective Kit $49.99
- Owens Corning Kit (Select Locations) $89.99
Canadian Tire
Canadian Tire stocks insulation materials but rarely carries pre-made garage door kits. You can buy foam board and reflective rolls to make your own kit, which costs less but requires more effort.
Products Available
- Reflectix Insulation Roll (48" x 25') $39.99
- Styrofoam Insulation Board (various) $15-$40
- Garage Door Bottom Seal (weatherstripping) $24.99
DIY Option: You can create your own kit with foam board ($40) + adhesive ($10) + tape ($8) for under $60, but expect 2-3 hours of cutting and measuring. See our DIY insulation guide for step-by-step instructions.
