Glass edge sealant curing system including a method and apparatus for curing edge sealant around a stack of Thermopane windows. Infrared heating units abut three sides of the edges of a stack of Thermopanes on a conveyor. One of the infrared heating units moves in a path perpendicular to the conveyor travel, traveling in and out towards one of the edges of the glass. Once the three edges have been cured, the infrared heating unit across the conveyor raises up to allow the stack of panes to pass underneath and subsequently moves back into position for heating of the trailing edge of the stack of Thermopanes. The heaters are controlled according to one or more algorithms providing for appropriate energy consumption. Optical sensors are provided for determining the height of a stack of Thermopanes, as well as the length and width for appropriate heater energization, and thermopiles are provided for sensing the appropriate curing. A programmed microprocessor controls the entire apparatus, including the conveying of the panes, the movement and the energization of the heater units, and subsequent discharging of the stack of Thermopanes.
