Energy transfer through a material because of a temperature difference, without the material moving as a whole.
Revise: Reducing Unwanted Energy TransferTrapped air reduces conduction and convection, but it does not prevent transfer by infrared radiation. Shiny surfaces can provide an additional insulating effect because they are poor absorbers and emitters of infrared radiation and reflect much of the radiation that reaches them.
