ENERGY STAR® is a joint green program of the U.S. Environmental Protection Agency, the U.S. Department of Energy, and the Canadian National Resource Council that helps consumers identify the most energy-efficient products on the market.

Energy efficient choices can save families about a third on their energy bill with similar savings of greenhouse gas emissions, without sacrificing features, style or comfort.

Columbia has obtained ENERGY STAR® certification on all glass skylight models including fixed and venting, curb mount and self flashing.

Columbia offers a wide range of ENERGY STAR® glazing, including clear, Neat, bronze/grey tint and bronze/grey solar reflective options. All are supplied with Cardinal Low E3 366 glass

How Does the ENERGY STAR® skylight program work?

North America has been divided into several climate zones. The climate zones for which a window, door or skylight is ENERGY STAR® qualified will be shown on a label or on its sales literature. Simply choose a product model that is qualified for the climate zone that you live in.
