When it comes to energy efficiency,
our star is shining brighter than ever.
To save money year after year on heating and cooling costs, make sure your windows and doors are Energy Star® qualified. Energy Star® is a program run by the United States Department of Energy and Environmental Protection Agency, and is designed to help individuals and businesses protect the environment through superior 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 country. These ratings are achieved through independent testing done to NFRC (National Fenestration Ratings Council) standards. The ratings that a specific window or door achieves will vary due to the type of glass used, the window or door style and the overall product design. Wincore is proud to be an Energy Star® partner, signifying that our products can be ordered to meet Energy Star® guidelines.
