A vacuum insulating glass (IG) unit and method-of making the same. An edge-mounted pump-out structure is provided, including a pre-positionable insert capable of receiving a pump-out tube therein. Following formation of the edge-mounted pump-out structure and its positioning on the unit, an edge seal is formed for hermetically sealing off the low pressure space located between the substrates.

1. A thermally insulating glass panel comprising:first and second spaced apart glass substrates defining a low pressure space therebetween having a pressure less than atmospheric pressure; a plurality of spacers disposed between said first and second glass substrates for spacing said substrates from one another in order to maintain said low pressure space therebetween; a pump-out insert including an elongated aperture defined therein, said pump-out insert at least partially located on an approximately L-shaped step or ledge defined by the first and second glass substrates; a pump-out tube disposed at least partially within said elongated aperture of said insert; and an edge seal at least partially provided in said approximately L-shaped step or ledge for hermetically sealing said low pressure space, and wherein at least a portion of said edge seal is provided over at least a portion of said pump-out insert.
