If you’re looking to improve your home’s energy efficiency, comfort, and even security, double-glazed windows should be at the top of your list. Whether you’re dealing with extreme temperatures, high energy bills, or outside noise, these windows provide a long-term solution that pays off in more ways than one.
As an experienced window installation company in Wisconsin, our team has seen firsthand how double-glazed windows transform homes in the Midwest. In this guide, we talk about everything you need to know about how double-glazed windows work, their key benefits, and why they’re a smart investment for your home.
What Are Double-Glazed Windows & How Do They Work?
For years, windows came with a single glass, bound by a frame. Though it did fulfil its purpose, it had a major impact on energy efficiency. Glass is a poor insulator, and with these windows, heat is easily able to escape during the winter and enter during the summer, leading to uncomfortable temperatures indoors.
This is where double-glazed windows come in.
Unlike traditional single-pane windows, double-glazed windows have two layers of glass separated by a sealed gap filled with air or an insulating gas (such as argon or krypton). This design creates a thermal barrier that reduces heat transfer between the inside of your home and the outside world.
Double glazing slows down this exchange of heat. How? With two panes of glass and a gas fill to pass through, sunlight has to travel through much more than just a single pane. The gas-filled space between the panes acts as insulation, keeping indoor temperatures more stable year-round. That means lower energy bills, fewer temperature fluctuations, and a more comfortable home overall.
Double-glazed glass windows are now the first choice for many homeowners, especially in Midwestern states like Wisconsin, where the weather is generally very cold.
The Key Benefits of Double-Glazed Windows
Double-glazed windows have been a welcome advancement in the window industry. This is why more than 50% of homes in America have double-glazed panes and why you should consider their installation as well.
Double-Glazed Windows Can Bring Your Energy Bill Down
Did you know that 25% to 30% of residential heating and cooling energy is lost through windows? If your home has old, single-pane windows, you’re likely paying more than necessary to keep your home comfortable. This makes one of the most compelling reasons for installing double-glazed windows their substantial contribution to energy efficiency.
With double-glazed windows, you reduce energy loss significantly, which translates into:
- Lower heating costs in winter, which are quite long here in Wisconsin. Double-glazed windows help keep warm air inside where it belongs.
- Reduced cooling costs in summer by blocking excess heat from entering.
- Up to 15% savings on annual energy bills, depending on your climate and HVAC efficiency.
Over time, the savings on heating and cooling bills help offset the initial cost of installation.
More Comfort For Your Home!
Temperature irregularities not only reduce the energy efficiency of your home, they also make your home feel uncomfortable, especially near windows. If you’ve ever avoided sitting near a window in winter because it’s too cold, you know this problem well.
With double-glazed windows, you eliminate drafts and hot spots by keeping indoor temperatures more consistent. Your home will feel cozier in winter and cooler in summer, no matter where you sit.
These windows also help reduce condensation, as the consistent temperature ensures that the moisture does not settle inside. This can lead to mold and mildew issues in poorly insulated homes.
Noise Reduction: A Quieter, More Peaceful Home
If you live near a busy road, airport, or urban area, outside noise can be frustrating. Double-glazed windows provide superior sound insulation compared to single-pane glass. Why? The space between the panes absorbs sound waves better, acting as a buffer against outside noise.
If you need even greater noise reduction, you can choose laminated glass or triple glazing for maximum soundproofing.
What to Consider When Installing Double-Glazed Windows
Before you invest in double-glazed windows, it’s essential to understand the factors that influence their efficiency, durability, and performance. Here are key considerations to keep in mind:
Choosing the Right Frame Material
The type of frame you choose not only affects the appearance of your windows, but also their insulation properties, durability, and maintenance requirements. Here are the three most popular options:
- uPVC (Unplasticized Polyvinyl Chloride):
This is one of the most common choices for window frames due to its affordability, durability, and low maintenance needs. uPVC does not rot, warp, or require frequent painting, making it an excellent long-term investment.
- Wood
Wooden frames were your only option back in the day and can still be found today. They offer a classic look that enhances the appearance of your home, making them a popular choice for traditional or historical houses. They offer excellent insulation properties, helping to reduce energy loss.
- Aluminum
Aluminum frames are known for their modern, sleek appearance and exceptional strength, making them a top choice for contemporary homes. Unlike wood, aluminum is resistant to warping, rotting, and corrosion, requiring minimal maintenance. However, standard aluminum frames are not as energy-efficient as uPVC or wood.
Selecting the Best Glass Type
The type of glass you choose has a significant impact on the overall performance of your double-glazed windows, influencing factors such as energy efficiency, glare reduction, and noise insulation. Here are the main options:
Low-E (Low Emissivity) Glass:
This type of glass has a special microscopic coating that reflects heat back into your home while still allowing natural light to pass through. Low-E glass significantly improves energy efficiency without compromising visibility, making it an ideal choice for climates with extreme temperatures.
Tinted Glass:
Tinted glass helps reduce glare and blocks excessive heat from entering your home, making it particularly useful in sunny climates or rooms that receive a lot of direct sunlight. The tinting reduces the amount of UV rays that pass through the glass. While it slightly darkens the room, it improves energy efficiency and enhances comfort by reducing the intensity of sunlight exposure.
Laminate Glass:
This type of glass consists of two or more layers bonded together with an interlayer of plastic in between, creating a strong, shatter-resistant surface. Laminated glass enhances security by making it harder for intruders to break through, and it also significantly reduces noise pollution.
Professional Installation Matters
Even the best windows won’t perform well if they’re poorly installed. Proper installation ensures that your windows are airtight, energy-efficient, and long-lasting. Here’s why professional installation is crucial:
Prevents Condensation Between Panes:
Poor installation can let moisture enter between the glass panes, causing foggy windows and signaling lost insulating gas. A proper seal keeps the unit clear and energy-efficient.
Prevents Gas Leaks:
The insulating gases inside double-glazed windows, like argon or krypton, boost thermal performance. Poor sealing during installation can cause these gases to leak, reducing efficiency. Expert installation protects against this.
Eliminates Drafts and Heat Loss:
Small gaps from incorrect fitting allow air to sneak in or out, making your HVAC system work harder. Professional installers ensure airtight seals to keep your home comfortable year-round.
