An investigator has reported some high values for the thermal conductivity of some metal air laminates both varnished and otherwise. See Taylor, T.S., Elec. World Vol 76 (24), 1159–62, 1920 in TPRC Data Series Vol 2, pp 1037–9.

k is the thermal conductivity of the material and h is the heat transfer coefficient. [1] [5] The second chart is used to determine the variation of temperature within the plane wall at other location in the x-direction at the same time of for different Biot numbers. [1]
The thermal conductivity of a material is a measure of its ability to conduct heat.It is commonly denoted by , , or and is measured in W·m −1 ·K −1.. Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity.
Its thermal conductivity (2,200 W/m•K) is five times greater than the most conductive metal (Ag at 429); 300 times higher than the least conductive metal (Pu at 6.74); and nearly 4,000 times that of water (0.58) and 100,000 times that of air (0.0224). This high thermal conductivity is used by jewelers and gemologists to separate diamonds from ...

A Berkeley-led study in 2016 by S. Lee et al. also found a large violation of the Wiedemann–Franz law near the insulator-metal transition in VO 2 nanobeams. In the metallic phase, the electronic contribution to thermal conductivity was much smaller than what would be expected from the Wiedemann–Franz law.
