Abstract
A vacuum insulating (IG) unit and method of making the same. A low pressure space is provided between opposing substrates. An edge sealing system includes at least first and second edge seals. A plurality of spacers or pillars are located at least partially between the first and second edge seals, in order to better control the gap or spacing between the two opposing substrates.

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 first 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;
- an edge sealing system including first and second seals of different materials;
- and
- a second plurality of spacers, wherein at least some of said spacers of said second plurality are located at least partially between said first and second seals.
