When it comes to facing Canada’s unpredictable weather, your windows do far more than frame the view. They’re key to keeping your home comfortable, controlling energy use, and even increasing resale value. If you’re living in London, Ontario, you know how brutal winters and sticky summers can be. That’s why energy efficiency isn’t just a nice-to-have—it’s essential. But what exactly makes a window energy efficient? And how can you feel confident that you’re choosing the right option?
With more than 60 years of experience in home improvements, we know precisely what homeowners should look for when it’s time to upgrade their windows.
Why Energy Efficiency in Windows Matters
Before diving into the details, let’s look at why energy-efficient windows should be a priority. In a place like London, where temperatures swing from icy cold to sweltering hot, poor-quality windows can drive up your heating costs in winter and make it nearly impossible to stay cool in summer.
Energy-efficient windows help stabilize indoor temperatures by limiting unwanted heat transfer. That means less dependence on your HVAC system and noticeably lower utility bills. Plus, you’re reducing your home’s carbon footprint—a win for the environment.
The Building Blocks of an Energy-Efficient Window
Not all windows are built the same. Here are the most important features our experts at AM Group Exteriors recommend paying attention to:
1. Multiple Panes of Glass
Double- and triple-pane glass dramatically reduces heat loss. These layers create an insulating barrier that keeps your indoor air where it belongs.
2. Low-E Coatings
Low-emissivity (Low-E) coatings are ultra-thin metallic layers that reflect heat back inside during winter and block excess solar heat in summer.
3. Gas Fills
Filling the spaces between panes with argon or krypton gas improves insulation. These gases are better at slowing heat transfer than regular air.
4. Quality Frame Materials
Frames made from vinyl, fibreglass, or composite materials deliver superior thermal performance. Vinyl is especially popular in London, Ontario, thanks to its durability and excellent insulation properties.
5. Warm Edge Spacers
Spacers hold glass panes the right distance apart and prevent condensation. Warm edge spacers use low-conductivity materials to further enhance energy efficiency.
6. Expert Installation
Even the best windows won’t perform well without proper installation. That’s why partnering with a trusted company like AM Group Exteriors is critical. Our experienced installers ensure every window is sealed and fitted to perfection.
Reading the Labels: What Do Those Numbers Mean?
Shopping for new windows can feel overwhelming with all the performance ratings. Here’s what you need to know:
U-Value: Indicates how well a window prevents heat from escaping. Lower numbers mean better insulation.
SHGC (Solar Heat Gain Coefficient): Shows how much solar heat comes through the glass. A lower SHGC is best if your home gets lots of sun.
ENERGY STAR Certification: In Canada, this label guarantees the window meets strict energy efficiency standards set by Natural Resources Canada.
The London, Ontario Advantage
London homeowners face a unique combination of weather extremes. Upgrading to energy-efficient windows and doors in London, Ontario, isn’t just about comfort—it also improves insulation, reduces condensation, and enhances indoor air quality.
On top of performance, you get aesthetic upgrades. Modern, efficient windows elevate curb appeal and bring fresh style to any home exterior. Not sure which style is best? Our team provides guidance, selection, and professional installation every step of the way.
Additional Benefits of High-Performance Windows
Many homeowners underestimate just how much value energy-efficient windows can deliver beyond comfort and savings. New windows also create a quieter indoor environment by blocking outdoor noise—an essential benefit if you live near busy roads or urban areas in London.
They also help protect your belongings. The advanced Low-E coatings reduce UV rays entering your home, preventing your furniture, flooring, and drapes from fading over time.
And let’s not forget peace of mind. Modern window designs include enhanced locking mechanisms and sturdy materials that improve your home’s security. For families who want both safety and efficiency, this combination makes new windows a smart, long-term investment.
Cost vs. Long-Term Value
It’s true that energy-efficient windows may have a higher initial cost compared to basic options. But when you factor in lower monthly energy bills and the increased resale value they bring, the long-term savings more than justify the expense.
According to Natural Resources Canada, upgrading to high-efficiency windows can cut heating and cooling costs by up to 15%. Over the years, those savings can add up to thousands of dollars—making this improvement a smart financial decision.
And when it’s time to sell, modern, efficient windows are a major selling point that can set your property apart.
