energy-star-largeIf you want to save money on your home heating and cooling bills—and ensure your home is as comfortable as it can be—you should surely consider windows and doors that are ENERGY STAR® qualified. These windows will not only improve the thermal efficiency of your home, but they’ll also help protect the environment.


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-Factor 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.

* National Fenestration Rating Council, a federal program created to establish standardized testing procedures and ratings of window and door products.


All Soft-Lite vinyl windows and patio doors that incorporate any of Soft-Lite’s numerous high-performance glass options meet ENERGY STAR requirements and therefore are ENERGY STAR labeled. Soft-Lite windows have consistently achieved some of the highest NFRC ratings in the industry.


Most Soft-Lite windows have been recognized as ENERGY STAR Most Efficient Products. The ENERGY STAR Most Efficient 2017 designation recognizes the most efficient products among those that qualify for the ENERGY STAR. Double-hung, sliding and picture windows from every one of Soft-Lite’s product lines — including Barrington, Bainbridge LE, Pro, Classic, Imperial LS and Elements — have earned the Most Efficient designation with various high-performance, insulated glass systems. Soft-Lite windows had to meet strict criteria to earn the prestigious Most Efficient distinction.
