Heat flow which, in static conditions, crosses the surface of a homogenous material. Thermal conductivity is a measurement of the ability of a material to transmit heat. As shown in the diagram below, the lower the value λ of a material, the better the thermal insulation.

|Aluminium λ = 200 W/mk|
|Water λ = 0.58 W/mk|
|Wood λ = 0.12 W/mk|
|Elastomer λ = 0.033* W/mk|
