Krypton Gas

Last Updated: November 23, 2023

Krypton gas is a very rare gas that is 1 part per million in the earth’s atmosphere and 600 times the price of argon gas. It is denser than argon gas and is only effective if trying to increase performance of very narrow airspace insulating units. Krypton does not have a justified performance or cost benefit in wider airspaces.
