Coefficient of thermal transmission of air and common gases

Thermal transmission coefficients (lambda) of the most common atmospheric gases (Air, Argon, Krypton and Xenon)

Air is an excellent insulator, which is why it is widely used in insulating materials. This article is part of a general article on the heat transfer coefficients

Lambda given in W / mK

  • Air 0.025

  • argon 0.017

  • krypton 0.009

  • xenon 0.0054
