AbstractInterior surface temperatures at the edges of sealed double- glazing units are lower than those of many conventional double window arrangements, and the building humidities that can be carried without excessive condensation on these surfaces are correspondingly lower. They must be sealed initially with dry air between the panes, and in spite of the stresses imposed by service conditions must retain the seal over their required service life. Units can fail by either breakage or condensation and the scumming that results from excessive moisture gain. On the other hand, sealed glazing units have advantages in the elimination of storm sash, reduction of surfaces that need cleaning to two, and prevention of condensation between panes. These may often outweigh the potential problems in their use.
