According to the U.S. Department of Energy (DOE), over 30% of a home's heat loss happens through windows. Modern replacement windows offer durability, lower energy bills, boost home value, reduce maintenance, and enhance both the inside and outside appearance of your home.

Yes, especially when you choose high-quality, energy-efficient options. Windows with insulated frames and energy-efficient glass help keep your home comfortable year-round, reducing the need for constant heating and cooling. With low-maintenance materials like vinyl or fiberglass, upkeep is minimal, eliminating the need for painting or scraping. These savings on energy and maintenance can help you recover your investment in just a few years.

Look for a label from the National Fenestration Rating Council (NFRC) on any replacement window. The NFRC tests and rates windows based on energy performance, ensuring that the windows meet industry standards. This label guarantees that the windows you select will be energy-efficient for your needs.

Vinyl or fiberglass frames with multi-chambered construction and fusion-welded corners are the best for energy efficiency. When paired with an insulated frame and a Low-E glass package, they provide superior thermal performance.

Insulated glass features two or more panes with space in between for better insulation. The greater the gap between the panes, the better the window’s ability to insulate. Filling the space with inert gases like argon or krypton slows heat transfer, reducing the energy needed to heat or cool your home.

Low-E glass stands for low emissivity glass, which has a thin metallic coating that reflects heat. In the summer, it keeps the heat out, while in the winter, it helps retain indoor warmth. Low-E glass also blocks UV rays, helping to prevent your furniture and carpets from fading.
