Thermal conductivities have been measured with longitudinal heat flow methods where the experimental arrangement is so designed to accommodate heat flow in only the axial direction, temperatures are constant, and radial heat loss is prevented or minimized. Note: There are no negative conductivities and the symbols that could be read that way are hyphens to separate various estimates and measurements. Related Topics . Thermal bridging refers to the loss of building energy through thermal conductivity of elements that "bridge" across the insulation of a wall or roof enclosure of a conditioned (i.e., heated or cooled) space when the outside temperature is warmer or colder than the interior space.
