Double pane windows have two sheets of glass with a sealed space between them. That space is filled with a (not regular air) to improve insulation. double pane window gas

There are two primary gases used in the residential window market. While they perform the same function, they have distinct differences in performance and cost.

In almost every climate, the answer is . The price difference between a standard air-filled window and an Argon-filled window is usually marginal, while the energy savings over the life of the window are substantial. Argon is the industry standard for residential windows

Krypton is denser and a better insulator than Argon, but it is much rarer and more expensive to produce.

When it comes to energy-efficient windows, double pane windows are a popular choice among homeowners. One of the key features that make them so effective is the gas that fills the gap between the two panes of glass.
