Abstract
A vacuum insulating panel includes first and second substrates (e.g., glass substrates), a hermetic edge seal, a pump-out port, and spacers sandwiched between at least the two substrates. The gap between the substrates may be at a pressure less than atmospheric pressure to provide insulating properties. The vacuum insulating panel may include ceramic (e.g., aluminosilicate glass) spacers, which may be chemically strengthened.

1-59. (canceled)
A vacuum insulating panel comprising:
- a first substrate;
- a second substrate;
- a plurality of spacers provided in a gap between at least the first and second substrates, wherein the gap is at pressure less than atmospheric pressure;
- a seal provided at least partially between at least the first and second substrates;
- and
- wherein at least one of the plurality of spacers comprises ceramic material, and comprises a compressive stress region and a tension stress region, wherein tensile stress in at least part of the tension stress region is at least about 25 MPa.
