A Guide for Homeowners

Understanding Energy-Efficient Windows

Windows have come a long way from being mere openings in walls. Today, they play a vital role in keeping your home comfortable while saving on energy costs. In fact, windows cover only 10 to 15 percent of the total wall area in an average home but are responsible for 20 to 30 percent of its energy loss. Let’s explore how energy-efficient windows can enhance your home’s comfort and reduce energy expenses.

The Importance of Energy-Efficient Windows

Energy-efficient windows offer numerous benefits beyond just keeping the weather elements at bay. They:

  1. Reduce Drafts and Increase Comfort: Good windows eliminate drafts, ensuring a more comfortable living environment for you and your family.
  2. Noise Reduction: Energy-efficient windows also block exterior noise, providing a peaceful ambiance inside your home.
  3. Fade Protection: They offer fade protection to your carpeting and furnishings, preserving their appearance and longevity.
  4. Enhance Home Value: Investing in energy-efficient windows can increase the value of your home, making it an appealing choice for potential buyers.

Key Components of Energy-Efficient Windows

Energy-efficient windows consist of three integral parts – glazing (glass), edge spacers, and frames – each contributing to your home’s overall comfort and energy conservation.

  1. Glazing or Glass: Single-paned windows provide little insulation, while two panes are more efficient. For even better performance, consider Low-E glass, which uses a colorless, invisible coating to reflect heat, making double-paned windows as effective as triple-paned ones.
  2. Edge Spacers: Modern edge spacers are made of materials like structural foam, slowing down heat transfer and boosting energy efficiency compared to traditional aluminum spacers.
  3. Frames: The framing material can significantly impact a window’s efficiency and energy costs. Metal frames conduct heat quickly, but those with thermal breaks offer better insulation. Wood frames conduct heat slowly but require more maintenance. Vinyl frames provide efficiency comparable to wood and require less upkeep.

Choosing the Right Windows

When deciding on new windows, consider factors like budget and window orientation. Look for U-values displayed on windows, measuring the entire window unit’s efficiency. Lower U-values mean less heat transfer between indoor and outdoor air, resulting in better energy conservation. Shading Coefficient (SC) and Air Filtration (AF) are other measures of window energy efficiency to consider.

Proper Installation is Key

Even the most energy-efficient window requires proper installation for optimal performance. Weatherizing and insulating windows during installation is essential, and qualified installers can ensure your windows perform to their full potential.

By understanding the significance of energy-efficient windows and selecting the right options for your home, you can enhance comfort, save on energy costs, and make a wise investment in your property’s value.

Western Windows came highly recommended to us from one of their former customers. We still shopped around and got a few quotes from other companies. Although Western Windows were not the lowest price, it was evident their product is superior. We also liked the fact they are a family run business and their products are built locally in Calgary. But what really sets Western Windows apart from the other companies is their customer service. From their receptionists, to installers, to the owners of the company, their customer service is outstanding. We replaced ten windows and one sliding patio door. From the time of our initial contact, to the completion of the installation, this has been an easy, and pleasant experience. Thank you, Jeremy, and everyone at Western Windows! We highly recommend your company. Wendy and Steve
