Any homeowner is understandably interested in improving energy efficiency, especially with window replacements. If you’re one of them, understanding what makes a window energy-efficient is crucial to making informed decisions that impact both your comfort and utility bills. Here’s a quick post from Renewal by Andersen® of New Mexico to help you know more about it.
Components of Energy-Efficient Windows
Energy-efficient windows are composed of several key components that collectively contribute to their performance. These components include multiple glass panes, specialized frame materials, quality installation and Low-E coatings.
-
Multiple Glass Panes: Modern energy-efficient windows feature two or even three panes of glass. This design creates air or gas-filled spaces between the panes, serving as a barrier against heat transfer, which significantly improves insulation.
-
Specialized Frame Materials: The material of the window frame plays a significant role in energy efficiency. Materials such as fiberglass, vinyl and wood composites are preferred for their insulative properties, durability and low maintenance requirements.
-
Quality Installation: Even the most energy-efficient window will underperform if not properly installed. Hiring a reputable window and door contractor ensures that your windows are installed according to the manufacturer’s specifications and intended performance.
-
Low-E Coatings: Low-emissivity (Low-E) coatings are applied to glass to reflect infrared light, keeping heat inside during winter and outside during summer. This technology also protects against UV rays, helping to prevent fading of interior furnishings.
More About ENERGY STAR® Ratings
When selecting energy-efficient windows, one of the key indicators of a product’s performance is its ENERGY STAR® certification. This label is only awarded to windows that meet or exceed specific criteria set by the U.S. Environmental Protection Agency (EPA).
To be ENERGY STAR-certified, a window must demonstrate superior energy performance in various climate zones. These criteria consider factors such as the window’s U-factor, which measures the window’s insulative value, and the Solar Heat Gain Coefficient (SHGC), indicating how well the product blocks heat from the sun.
