Air Liquide offers gases for all industrial needs.


Air Liquide is the world leader in rare gases, including krypton. Our rare gas production and packaging facilities employ leading-edge technologies and advanced analytical equipment to produce customer-specific rare gas products like krypton. Air Liquide supplies krypton in many purity levels, from standard purity to ultra-high purity, for industrial, glass and lighting applications.

Insulated glass for windows


Air Liquide has worked with window manufacturers to help develop innovative technologies that improve the thermal and sound insulation characteristics of windows. Krypton is a better thermal insulator than air and three times less conductive. Its high density also reduces convection effects, further improving thermal insulation performance. Krypton also performs 50% better than air as a sound insulator. Air Liquide provides high-purity krypton that is ideally suited for insulated glass applications.



Krypton, neon and xenon are used with other gases in incandescent filament, fluorescent and discharge light bulbs to improve brightness, intensity, service life and color. Krypton is also used in the flashes of some high-speed photography.
