Notes heat flow through double windows due to temperature difference and air infiltration have usually been calculated separately. Tests combined effect of air pressure and temperature difference on three double hung prime windows in combination with various storm windows. Found that calculation of infiltration and transmission losses separately gives higher heating requirements than necessary and that air leakage increases with temperature differential. An overall heat transfer coefficient is determined
