ENERGY STAR®

What Is ENERGY STAR®?

ENERGY STAR® is a program run by the United States Department of Energy and Environmental Protection Agency that helps individuals and businesses protect the environment through greater energy efficiency. The ENERGY STAR® label can be affixed only to windows and doors that meet specific U-value and shading coefficient ratings for one or more regions of the U.S. These ratings are achieved through independent testing done to NFRC* standards. The ratings of one window will differ from another because of variables such as the glass used, style and product design.

ENERGY STAR® Qualified Windows

All of our windows and patio doors that incorporate any of our numerous low-emissivity (Low-E) high-performance insulating glass systems with argon or krypton gases meet ENERGY STAR® requirements and therefore are ENERGY STAR® labeled. Our windows have consistently achieved some of the highest NFRC ratings in the industry.

What Other Advantages Can I Expect From An ENERGY STAR® Window?

Some home furnishings and décor can actually suffer a kind of sunburn when continuously exposed to too much daylight. The ultraviolet (UV) rays from the sun can cause fading and degradation of many materials and dyes found in upholstery, carpet, artwork, wood or paint. Our energy efficient glasses can reduce harmful sun damage by 70% - 99, giving greater protection to your interiors.

ENERGY STAR® windows, by virtue of their design, eliminate draftiness and resist condensation for greater comfort. A well-insulated window also diminishes sound transmission.
