Performance Ratings – How They Work
Developed by the U.S. Department of Energy and the U.S. Environmental Protection Agency, the Energy Star program helps highlight the most energy efficient options for your home. The Energy Star seal can only be granted if the product clearly demonstrates a considerable reduction in the home’s energy consumption. Most of our windows and doors meet this strict criterion and many even exceed them according to U.S. and Canadian standards.
