A method and apparatus for heating and/or pressing sealant of an insulating glass unit. The apparatus may include an oven and a press. The oven includes a detector that detects an optical property of the insulating glass unit. The detected optical property is used to regulate the amount of energy applied to the insulating glass unit to adjust the amount of energy applied to the sealant. The press may include a displacement transducer that detects a pre-pressed thickness of the insulating glass unit. The measured pre-pressed thickness is used to automatically select a press thickness from a set of pressed IGU thicknesses.

1. A method of pressing an insulating glass unit, comprising:a) measuring an unpressed thickness of an insulating glass unit; b) comparing the measured unpressed thickness with a set of ranges of unpressed thicknesses that correspond to a set of insulating glass unit pressed thicknesses; c) selecting one pressed thickness from the set of insulating glass unit pressed thicknesses that corresponds to the measured unpressed thickness, wherein said one pressed thickness is less than said measured unpressed thickness; d) setting a distance between pressing members of a press to the selected one insulating glass unit pressed thickness unpressed; and e) passing the unpressed insulating glass unit through the press. 2. The method of claim 1 wherein said thickness of said unpressed insulating glass unit is measured before said unpressed unit is passed through an oven.3. The method of claim 1 wherein said thickness of said unpressed insulating glass unit is measured with a linear variable differential transformer displacement transducer.
