Insulated glass units increase the energy efficiency of your windows beyond ordinary clear glass. When you select Energy Star Rated as your glass type option in the window builder, Every Window automatically selects the glass type recommended by Energy Star for your region and specific climate challenges as delineated on the map below.

Selecting Basic Low E (Climatech) instead of Energy Star Rated in the window builder results in you getting the most common Energy Star Rated glass type. Climatech is the recommended glass type for the North-Central region and is a great option for most installations.

All windows sold by Every Window meet or exceed Air, Water and Structural Loads performanc requirements as determined through ASTM (American Society for Testing and Materials) test methods, the globally recognized standards for product quality and safety.

The Energy Star label certifies that the window is a positive choice for energy efficiency, fuel savings and the environment. Energy Star is a government-backed voluntary partnership program sponsored by the U.S. Environmental Protection Agency and the U.S. Department of Energy to help consumers recognize energy-efficient products. It’s good for you and good for the environment!
