Abstract

A vacuum insulating panel comprising: a first glass substrate; a second glass substrate; a plurality of spacers provided in a gap between at least the first and second glass 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 glass substrates is tempered, has compressive stress at a center of the glass substrate as viewed from above in a surface compression region of at least about 10,000 psi, and has one, two, or all three of: (i) a compressive stress proximate an edge of the glass substrate as viewed from above in the surface compression region of at least about 10,000 psi, (ii) tension stress at the center of the glass as viewed from above in the central tension region of at least about 5,800 psi, and/or (iii) compressive stress proximate a corner of the glass substrate as viewed from above in the surface compression region of at least about 10,000 psi.
