In figure, a film of still air was identified as the source of almost all of the thermal resistance of a single-pane glass window. Determine the thickness of the still air layers on both sides of the window if radiative heat transfer is ignored. It is estimated that about half the thermal conductance of the window is due to radiative heat transfer; estimate the thickness of the still air layers if this is the case.
