Heat flux measurement set-up
Heat flux measurement results

The R-value is a measure of thermal resistance used in the building and construction industry. Under uniform conditions it is the ratio of the temperature difference across an insulator and the heat flux (heat transfer per unit area per unit time, \dot Q_A) through it or  R = \Delta T/\dot Q_A. Thermal resistance varies with temperature but it is common practice in construction to treat it as a constant value.
