Did You Know? Our Canadian Climate Is Costing You Money Through Your Windows.
The average Canadian home loses up to 30% of its heating and cooling energy through windows. With our extreme temperature fluctuations from -30°C in winter to +30°C in summer, choosing between vinyl and aluminum windows isn’t just about aesthetics—it’s about protecting your comfort and your wallet. Most homeowners don’t realize that the wrong window material can increase energy bills by 15-25% annually, which translates to thousands of dollars over the lifetime of your windows.
As a sales consultant at Total Home Windows and Doors with over a decade of experience helping Canadian homeowners make informed decisions, I’ve seen firsthand how the right choice between vinyl and aluminum windows can transform a home’s energy efficiency, maintenance requirements, and overall comfort.
Vinyl Windows
Vinyl Windows
The Canadian Homeowner's Favorite
Vinyl windows, made from polyvinyl chloride (PVC), have become exceptionally popular among Canadian homeowners, accounting for over 70% of residential window installations. These windows offer excellent insulation properties through their multi-pane designs and air-tight seals.
Aluminum Windows
Sleek, Strong, and Sophisticated
Aluminum windows offer unmatched structural integrity with a distinctly contemporary look that architects and designers often prefer for modern homes. Typically finished with durable enamel paint or powder coating, these windows provide a sleek, minimalist aesthetic while allowing for larger glass areas and thinner frames.

What is the disadvantage of aluminum windows?
"When homeowners prioritize energy efficiency and value, vinyl windows consistently deliver the best return on investment," says Eugene Siukayev, Project Manager. "For most Canadian homes, vinyl offers the perfect balance of performance and affordability."
"The resurgence of aluminum windows in high-end Canadian homes is tied directly to the trend toward contemporary architectural styles with expansive glazing," explains Vitaly Shapiro, Vice President of Sales. "When clients want that dramatic wall of glass or floor-to-ceiling window experience, aluminum frames provide the necessary structural support while maintaining clean lines."
Side-by-Side Comparison: Thermal Break Aluminum Windows vs. Vinyl
When comparing energy performance, standard aluminum windows typically underperform compared to vinyl. However, thermal break aluminum windows—which incorporate a non-conductive durable material between interior and exterior aluminum sections—significantly narrow this gap.
"Thermal break technology has been a game-changer for aluminum windows in the Canadian market," explains Daniel Klein, Project Manager. "By reducing heat transfer through the frame, these advanced designs can achieve performance metrics much closer to vinyl, while still offering the aesthetic advantages of aluminum."
Even with thermal breaks, however, most energy efficiency testing shows that vinyl windows still maintain a slight edge in reducing energy consumption in harsh Canadian winters. Many homeowners in particularly cold regions like Northern Ontario or the Prairies choose vinyl for maximum thermal performance.
Vinyl Windows Cost vs. Aluminum Windows Cost
Cost remains one of the most significant factors in window selection. The average costs for standard-sized windows are:
| Window Type | Average Cost Per Window (Installed) | ROI at Home Sale |
| Vinyl Windows | $900 - $1,400 | 72.5% |
| Standard Aluminum | $1,100 - $1,800 | 69.3% |
| Thermal Break Aluminum | $1,300 - $2,200 | 70.8% |
These figures represent national averages for replacement windows, with considerable regional variation. Urban centers like Toronto, Vancouver, and Montreal typically see costs at the higher end of these ranges.
"For a typical three-bedroom home requiring 10-12 new windows, the cost difference between vinyl and premium aluminum can easily reach $5,000-$8,000," says Anna Klein. "That's why many homeowners carefully weigh the long-term energy savings against the upfront investment when deciding"
