Krypton (Kr):
Krypton is a noble gas often used in windows with a narrower gap between panes. It has excellent thermal insulating properties and outperforms air and argon as an insulating medium.
When incorporated into double or triple-pane windows, krypton significantly enhances energy efficiency by reducing heat transfer through the window assembly.
Argon:
Argon, another noble gas, is commonly used for insulation in newer and higher-grade windows. It is about 38% heavier than air, making it more resistant to heat conduction.
Argon fills the gap between panes, improving thermal performance and reducing energy loss.
Xenon:
Xenon, also a noble gas, finds applications in the window and lighting industry. While less common than argon and krypton, it contributes to specific window properties.
