Not All Windows Are Created Equal: What You Need to Know About Energy Star® Windows

If you’re looking for high-quality, energy-efficient windows in Tulsa or nearby areas, it’s important to understand that not all windows perform the same. Many homeowners confuse thermal windows with Energy Star® windows. However, these terms are not interchangeable.

What Are Energy Star® Windows?

Energy Star® windows are certified by the U.S. government and labeled by the National Fenestration Rating Council (NFRC). This means they meet strict energy efficiency standards and undergo independent performance testing. When you choose Energy Star® certified windows, you’re selecting products designed to reduce energy use, enhance comfort, and protect your home from extreme temperatures.

Why the NFRC Label Matters

When shopping for replacement windows, be sure to check for the NFRC label. This label confirms a window’s verified performance in areas such as insulation and energy savings. Unlike internal manufacturer ratings, the NFRC label is standardized and independently reviewed, giving you confidence in the window’s efficiency.

Key Energy Efficiency Terms

If you’re comparing Energy Star® replacement windows in Tulsa, understanding these terms can help:

• U-Factor: This indicates how well the entire window unit insulates. A lower number means better insulation.
• Solar Heat Gain Coefficient (SHGC): This shows how much solar heat the glass lets in. Lower values mean better cooling and shading performance.
• Air Leakage: This measures how much outside air passes through the window. A lower rating means a tighter, more efficient seal.

Our Energy Star® Window Features

At SRI Energy, we install Energy Star® replacement windows built for top-tier performance. These windows include:

• Vinyl frames that resist heat transfer
• Double- or triple-pane glass filled with argon or krypton gas for insulation
• Low-E coatings that reflect infrared heat and block UV rays
• Polyurethane foam-filled frames and sashes for greater energy efficiency
• Precision triple weather stripping that minimizes air leaks

These combined features help you stay comfortable year-round while reducing heating and cooling costs.

Understanding the Energy Star® Program

The Energy Star® program is managed by the U.S. Environmental Protection Agency (EPA). Its mission is to help individuals and businesses save money while protecting the environment. For windows to earn the Energy Star® label, they must meet specific performance criteria for insulation, sealing, and energy use.
