Window Replacement Services in London, Ontario
If your home feels chilly even with the furnace running—or you’ve noticed your energy bills creeping higher every month—your windows could be the culprit. Drafts, condensation, or fading furniture are often signs your windows aren’t doing their job anymore.
That’s where energy-efficient windows come in. For homeowners in London, Ontario, upgrading to modern, high-performance windows isn’t just about looks; it’s one of the smartest investments you can make in comfort, savings, and sustainability.At AM Group Exteriors, we’ve been helping Ontario homeowners improve their homes with energy-efficient upgrades since 1956. Here’s what these windows are, how they work, and why they’re worth every penny.
What Makes a Window Energy-Efficient?
Not all windows are created equal. Traditional single-pane windows let heat escape in the winter and pour in during the summer. Energy-efficient windows, on the other hand, use advanced technology to reduce heat transfer, block UV rays, and maintain a comfortable temperature inside your home—no matter what London’s weather throws your way.
In Canada, the ENERGY STAR® label is the standard to look for. These certified windows meet strict performance criteria for insulation, airtightness, and solar control.
How Energy-Efficient Windows Work
Energy-efficient windows are designed to keep the heat where you want it—inside during winter and outside during summer. They achieve this through a combination of advanced materials and construction features.
1. Multiple Glazing Layers
Double- or triple-pane glass creates layers of insulation. The space between each pane acts as a thermal barrier that slows down heat loss and prevents condensation.
Why it matters in London: Our fluctuating temperatures mean you need windows that can handle both extremes—keeping your home warm in January and cool in July.
2. Low-E Coatings
Low-emissivity (Low-E) coatings are microscopic metallic layers applied to the glass. They reflect infrared heat back into your home in winter and block harmful UV rays in summer.
Bonus: They help protect your flooring, curtains, and furniture from fading.
3. Argon Gas Fills
The spaces between panes are often filled with inert gases like argon. These gases are denser than air and reduce heat transfer even further.
Think of it as invisible insulation—keeping warmth inside where it belongs.
4. Insulated Frames
Energy-efficient windows aren’t just about glass. The frame material plays a big role, too. Vinyl, fiberglass, and composite frames provide excellent insulation and resist warping and condensation.
At AM Group Exteriors, we use proprietary, high-quality window systems that combine durability, weather-tight seals, and energy-saving technology—perfect for the London climate.
The Benefits of Energy-Efficient Windows
Upgrading your windows is one of the best ways to improve your home’s performance. Here’s what you can expect:
- Lower Energy Bills: Reduce heating and cooling costs by up to 30%.
- Enhanced Comfort: No more cold drafts, uneven temperatures, or hot spots.
- Noise Reduction: Multi-pane glass and tight seals keep outdoor noise out.
- Less Condensation: Prevents moisture buildup that leads to mould or rot.
- Eco-Friendly Living: Reduce your carbon footprint with lower energy use.
- Increased Home Value: Energy-efficient upgrades are attractive to buyers.
Whether you’re in a modern subdivision or one of London’s older neighbourhoods, these benefits make a noticeable difference year-round.
When to Replace Your Old Windows
Many homeowners don’t realize how much energy (and money) they’re losing through outdated windows. It might be time for a replacement if you notice:
- Drafts near windows or noticeable cold spots
- Condensation between panes
- Cracked glass or warped frames
- Difficulty opening or closing windows
- Rising energy bills despite no change in usage
If your windows are 20 years old or more, even if they look fine, technology has improved so much that new replacements will deliver significantly better performance.
