Nineteen U.S. Governors have recognized window film for its ability to efficiently reduce a building’s energy use, resulting in fewer carbon emissions and delivering other consumer benefits, such as protection from ultraviolet (UV) rays.

To raise public awareness of the benefits of window film, International Window Film Association (IWFA) members annually notify their state governors about the upcoming Window Film Day occurring on April 30. The following U.S. states and their governors have already proclaimed this year’s National Window Film Day, first held in 2014.

• Alabama

• Connecticut

• Delaware

• Georgia

• Illinois

• Indiana

• Kansas

• Louisiana

• Massachusetts

• Minnesota

• Missouri

• Nebraska

• New Hampshire

• North Dakota

• Pennsylvania

• Virginia

• West Virginia

• Wisconsin

• Wyoming

“We are grateful to the many U.S. governors that have shined a spotlight on window film and the wide spectrum of benefits it provides to consumers to reduce their energy use and also, by reducing peak energy demand, to help utilities,” says Darrell Smith, executive director of the IWFA. “Window films also provide similar energy savings, glare reduction and UV protection on automotive glass for consumers while in their vehicles.”

Professionally-installed window films may upgrade existing windows to improve their energy saving performance at a fraction of the cost of replacement windows, resulting in a reduction of a building’s carbon emissions, according to the IWFA. Other immediate benefits include blocking 99% of the sun’s UV rays that contribute to the fading of interiors and floors, and even offering some improved safety from dangerous glass shards that may result from broken glass.
