Abstract
A method of manufacturing VIGUs and IGUs comprises providing a first lite; providing a second lite spaced apart from the first lite to form a cavity therebetween; and encircling the lites with a one piece band. Spacers of a metal solder alloy or other reflowable material are inserted between the band and the perimeter edges of the lites. The assembly is heated in an evacuated environment, causing the spacers to melt and hermetically bond to the lites, but not until the cavity has been substantially evacuated.
