The thermal resistance of airspaces in building constructions
Abstract This paper reviews the basis of the conventional values of airspace resistance which are generally assumed in the calculation of U-values. These values are derived from measurements on large air cavities whose dimensions normal to the heat flow direction are large compared to its width; the implications for smaller rectangular airspaces are considered. It is concluded that it is a reasonable approximation in the calculation of U-values to ascribe a thermal resistance to the airspace, independent of the temperature difference across it but in general on its shape.
