The window edge-of-glass region temperature profile improvement by inserting a small additional glass pane-a CFD study and measurements

The internal surface temperature of windows is not uniform with a significant drop in temperature at the edge-of-glass region. This in turn can lead to heat loss and air humidity condensation, especially at the lower part of a window. In this paper the way to increase the interior pane surface temperature profile by inserting additional small thin glass pane is presented. A two-dimensional CFD simulation of a standard two pane glazing and glazing with an additional glass pane is presented along with results of measurements obtained by a thermographic camera.
