You’ve heard that double and triple pane windows can be filled with gas for better energy efficiency, but when it comes to making the decision for your new windows, which is better – Argon, Krypton… or no gas at all?
Argon
Argon is the most common gas used between windowpanes today. It is a colorless, odorless, inert gas found in our atmosphere that is denser than air – six times denser, to be exact. Windows filled with Argon have a slightly higher efficiency rating over windows that have no gas inserted between the panes. Argon gas performs the best in double-pane windows that have a ½ space or wider between the panes.
Krypton
Krypton, like Argon, is a colorless, odorless, inert gas that is denser than air – although in Krypton’s case, it’s twelve times denser than air as opposed to six times. Because of Krypton’s higher density it is twice as effective as Argon in slowing thermal energy from passing through a window. However, due to the scarcity of Krypton (it’s only found in trace amounts in our atmosphere), it is more expensive than Argon. It is most effective in triple-pane windows that have a ¼ to 3/8-inch space between the glass.
So, which is better – Argon or Krypton… or is the additional cost of adding gas not worth it at all?
Adding gas to your new windows does increase energy-efficiency overall. When it comes down to making a choice, the primary difference between Argon and Krypton is their density (and therefore their energy-efficiency), and the cost. Argon most often is a better value for homeowners, however which is best for your home comes down to the number and locations of your windows, whether the windows are double or triple paned, and the quality of your HVAC system.
