Climate zone map

The ENERGY STAR climate zone map shows how to select the right window films by dividing the U.S. into zones with specific performance criteria for windows. To choose the right window film, determine your climate zone using the map, and then select a film that helps your windows meet the U-Factor (insulation) and Solar Heat Gain Coefficient (SHGC) (heat blocking) requirements for that zone.
