How does Argon and Krypton Gas work?
Argon and Krypton Gas are the most common gasses used to fill the insulating layer between the panes of glass in an IGU. These gasses are used because they are more dense than the air we breathe making them better insulators. Krypton Gas is slightly denser allowing for a better energy saving performance rating than Argon Gas. Despite the better performance gained by using Krypton Gas, Argon Gas is more commonly used. It is more abundant than Krypton Gas making it much more affordable and gives only a marginal worse performance than Krypton Gas. Neither gas is toxic.
