Most modern windows offer reliable energy efficiency, especially compared to decades ago. However, if you want the best performance, you’ll want to focus on a few specific features. Here are some main details when comparing energy-efficient windows in Centreville, VA.
U-Factor or U-Value
The U-factor, or U-value, of a window measures its insulation effectiveness. A low U-factor means that the window is better at insulating. A good U-factor allows the window to keep heat inside your home during colder months, which may help lower your energy bills.
Quality of Frame Materials
The material of the window frame affects its insulation properties. Fiberglass, wood, composite, and vinyl offer different levels of thermal resistance and durability. Companies such as Window World of Washington, D.C., choose vinyl frames because they combine these features.
Glazing and Coatings
Modern energy-efficient windows often feature multiple panes of glass. The space between the panes is filled with inert gas, such as argon. This increases the insulating properties of the window.
Air Leakage (AL)
Most windows include an air leakage (AL) rating. This rating quantifies the amount of air that passes through the window assembly. A lower AL rating means that the window is more effective at keeping the indoor air in and the outdoor air out, increasing your home’s energy efficiency and comfort.
Consider these details when looking for energy-efficient windows in Centreville, VA. Pay attention to the U-factor, the quality of the frame materials, the glazing and coatings, the air leakage rating, and the overall design.
