AbstractBoth inner and outer panes of a sealed double-glazing unit are susceptible to breakage by thermal stress. The breakage potentials of the inner and outer panes are dependent on the strength of the glass panes, the severity of the outdoor air temperature, the intensity of the incident solar radiation, the solar absorptance of the panes, the design of the window frame and glazing seals, and the configuration of the heater terminal unit and the indoor and outdoor shades. A number of solar-control sealed units, including clear, heat- absorbing and heat-reflecting units, were installed in the walls of the DBR Environmental Laboratory to determine the effect of solar radiation and outdoor air temperature on their breakage potentials. These breakage potentials, measured under real exposure conditions, are reported.
