Gas Fill Basics

There are two main types of gas used with residential windows; argon and krypton. Argon is the less expensive option and is ideal when there is airspace between the panes of 7/16" to 1/2". Krypton tends to be more expensive and is ideal when there is an airspace that measures 1/4" to 5/16". The gas is inserted between the glass panes during the manufacturing process and helps lower the amount of heat or cold that can transfer from one pane to the other. This help keeps the home cooler during hot months and warmer during cold months.

Window Gas Fill Costs

Expect argon fills to run an additional $25 per window and krypton fills to run roughly $50 per window. Many mid range to high end double pane windows come standard with argon gas fills. Some do not and offer this or krypton fills as an optional upgrade.
