What To Look For in Energy Efficient Windows
The right windows can make a huge difference in how comfortable your home feels and how much you spend on heating and cooling. So what are the most energy efficient windows? There are several factors that contribute to the most energy efficient windows. Let us walk you through the key things to look for and why proper installation can make a huge difference.
What Makes a Window Energy Efficient?
Knowing what features make a window stand out is essential to finding the most energy efficient windows for your home. Here are the key things to look for when choosing new windows.
U-Factor
The U-factor measures a window’s ability to insulate. It tells you how well the window prevents heat from escaping. The lower the U-factor, the better the window insulates. For homes in Colorado, where winters can be quite cold, choosing windows with a low U-factor is essential. Energy-efficient windows typically have a U-factor of 0.30 or less. This rating ensures that your home retains heat during the winter, reducing your reliance on heating systems and lowering your energy bills.
Solar Heat Gain Coefficient (SHGC)
The Solar Heat Gain Coefficient (SHGC) measures how well a window blocks heat from the sun. In hot climates, a lower SHGC is desirable to minimize cooling costs. For Colorado’s varied climate, windows with a moderate SHGC are ideal—they block unwanted heat during the summer while allowing some heat gain during the colder months. This balance helps maintain a comfortable indoor temperature throughout the year.
Energy Star Certifications
Energy Star certifications provide a reliable way to identify windows that meet high standards of energy efficiency. To earn this certification, windows must meet strict criteria for U-factor, SHGC, and other performance metrics such as visible transmittance and air leakage. Energy Star-certified windows are independently tested and verified to perform well in various climates, including Colorado’s. When selecting windows, look for the Energy Star label to ensure you’re choosing a product designed to reduce energy costs and increase comfort in your home.
Best Types of Energy Efficient Windows for Colorado’s Climate
Colorado’s climate, with its cold winters and warm summers, requires windows that provide excellent insulation and durability. These are some of the most energy efficient types of windows.
Triple-Pane Windows
Triple-pane windows offer exceptional insulation due to their three layers of glass with gas-filled spaces in between. This design minimizes heat transfer, enhances soundproofing, and significantly boosts overall energy efficiency, making these windows well-suited for Colorado’s diverse climate. Homeowners can consider trusted brands like Andersen and Pella for high-quality triple-pane options.
Low-E (Low Emissivity) Glass Windows
Low-E (Low Emissivity) glass windows are designed with a special coating that reflects infrared light, effectively retaining heat during winter and reflecting it away during summer. This feature helps reduce energy costs and also protects interior furnishings from early fading and UV damage, providing both efficiency and durability. Leading brands such as Simonton and Milgard offer excellent Low-E window choices.
Fiberglass Frame Windows
Fiberglass frame windows are known for their strength and durability, offering better thermal performance than vinyl or aluminum frames. These windows expand and contract less with temperature changes, ensuring a tight seal and long-lasting energy efficiency. Pella is a recommended brand for high-quality fiberglass frame windows.
Vinyl Frame Windows with Foam Fill
Vinyl frame windows with foam fill provide an affordable yet effective solution for energy efficiency. These windows are not only low-maintenance and resistant to warping but also offer excellent insulation properties, making them a favorite among homeowners. Pella is a reliable brand for foam-filled vinyl frame windows.
Wood-Clad Windows
Wood-clad windows combine the natural insulation properties of wood with the durability of exterior cladding materials like aluminum. This combination provides a perfect balance between aesthetics and performance, offering both insulation and protection. Andersen is a well-regarded brand for wood-clad window options.
Composite Frame Windows
Composite frame windows are constructed from a blend of materials, offering the best features of each, including strength and energy efficiency. These windows are strong, require minimal maintenance, and provide excellent thermal performance, making them versatile for various climates. Both Andersen and Pella offer high-quality composite window options.
Argon or Krypton Gas-Filled Windows
Argon or krypton gas-filled windows are designed with inert gases between the panes, providing excellent insulation compared to air-filled windows. These windows enhance energy efficiency and reduce heat transfer, making them highly effective for Colorado’s climate. Andersen offers several window options with argon or krypton gas.
Why Proper Window Installation Matters
Even the most energy efficient windows can fall short if not installed correctly. Proper installation ensures that the window fits tightly, preventing air leaks that can compromise insulation. Poorly installed windows can lead to drafts, condensation, and increased energy costs. So, while doing it yourself saves you money up-front, your windows may operate less efficiently. Hiring a professional for window installation is worth it in the long run.
Maintenance Tips to Boost Your Window’s Efficiency
Enhancing your home’s energy efficiency goes beyond installing the right windows—you also have to keep them in good shape. Regular maintenance can keep your home comfortable and your energy costs down. Caulking around windows to block drafts or adding weatherstripping to seal gaps makes a big difference. If you notice a cracked window, especially a double-pane one, fix it quickly. These panes often contain insulating gas, and once that leaks out, the window’s efficiency is reduced.
