description Double-Pane Windows Overview
Double-pane windows consist of two sheets of glass separated by a spacer, creating a sealed insulating air gap that reduces heat transfer. The space between the glass is frequently filled with an inert gas, such as argon or krypton, to further minimize thermal conductivity. These windows improve residential energy efficiency by reducing the load on heating and cooling systems. They are a standard component in modern construction and building retrofitting.
