Window films can be used for building insulation. Retrofit films are not required for modern windows that have low-solar gain glass. However, most windows don’t have low solar heat gains so window films can be used as a retrofit energy improvement. They can provide thermal comfort and are one of the most cost-competitive and environmentally-friendly energy improvements, especially in hot and mixed climates.
