Energy Star Insulated Windows

 

Not all Windows are Created Equal

Looking for quality, energy-efficient windows for your Tulsa, Oklahoma, or surrounding area home? Not all windows are created equal. There is often confusion about the difference between thermal windows and Energy Star® windows, but they are not interchangeable.

Energy Star® windows are those rated by the US government and carry an NFRC label showing the Energy Star® designation. This means that the window has been independently certified by the National Fenestration Rating Council (NFRC) and meets specific energy efficiency standards.

If you’re considering investing in replacement windows, it’s essential to ask about the NFRC rating for any window you’re considering. This helps ensure that you’re getting the best-insulated windows for energy efficiency standards, rather than just an internal rating.

Energy Star® Tulsa Replacement Windows

Let’s talk about some technical terms you may encounter when shopping for Energy Star® replacement windows in Tulsa.

  • U-factor: This is the rate at which a window conducts non-solar heat flow. The lower the U-factor, the more energy-efficient the window.
  • Solar heat gain coefficient (SHGC): This is the fraction of solar radiation admitted through a window. The lower the SHGC, the less solar heat the window transmits and the greater its shading ability.
  • Air leakage: This is the rate of air movement around a window in the presence of a specific pressure difference across it. A low air leakage rating means the window is tighter and more energy-efficient.
  • R-Value: This is the insulating value of the entire window unit, including the frame and spacer material. The lower the “U” value, the better the window will insulate.

At SRI Energy, we offer a full line of Energy Star® windows that comply with these standards. Our windows feature vinyl frames that block heat, double- or triple-pane glass with argon or krypton gas fill for improved insulation, “Low-E” glass coatings to help block UV rays, polyurethane foam fill within frames and sashes for added insulation, and high-end, precision-engineered triple weather stripping to block air and create a perfect fit. Tighter seals minimize air infiltration, keeping warm air inside during the winter and hot air outside during the summer.

What is an Energy Star® Window?

ENERGY STAR® is a U.S. Environmental Protection Agency (EPA) voluntary program that helps businesses and individuals save money and protect the climate through superior energy efficiency. Windows must meet minimum performance criteria during testing to qualify for the ENERGY STAR® label. The insulation properties of the entire window determine whether or not a window can be ENERGY STAR® labeled.
