OG exemplary drawing
 
1. 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, the seal comprising a first seal layer comprising tellurium oxide and a second seal layer,
wherein, for at least one location of the seal, the first seal layer has a first width and the second seal layer has a second width, wherein the first width of the first seal layer is from about 3-10 mm, and
wherein the tellurium oxide comprises TeO4 and TeO3, and wherein the first seal layer comprises more TeO3 than TeO4 by wt. %.
 
25. A vacuum insulating panel comprising:
a first tempered glass substrate;
a second tempered 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;
an edge seal provided at least partially between at least the first and second substrates, the edge seal comprising a first ceramic seal layer, a second ceramic seal layer, and a third ceramic seal layer, wherein the first ceramic seal layer is located between at least the second and third ceramic seal layers;
wherein the first ceramic seal layer comprises tellurium oxide, the tellurium oxide comprising TeO4 and TeO3, and wherein the first ceramic seal layer comprises more TeO3 than TeO4 by wt. %;
wherein, for at least one location of the seal, the first ceramic seal layer has a first width and the second ceramic seal layer has a second width;
wherein the second width of the second ceramic seal layer is at least about 1 mm greater than the first width of the first ceramic seal layer;
wherein, for the at least one location of the seal, an outer lateral edge of the first ceramic seal layer is spaced inwardly from an outer lateral edge of the second ceramic seal layer by an offset distance D of at least about 0.5 mm; and
wherein the first width of the first ceramic seal layer is from about 3-10 mm, and wherein a ratio Wp/W of the second width (Wp) of the second ceramic seal layer to the first width (W) of the first ceramic seal layer is from about 1.2 to 2.2.
 
26. A vacuum insulating panel comprising:
a first heat strengthened glass substrate;
a second heat strengthened glass substrate;
a plurality of spacers provided in a gap between at least the first and second glass substrates, wherein the gap is at a pressure less than atmospheric pressure;
an edge seal provided at least partially between at least the first and second substrates, the edge seal comprising a first ceramic seal layer, a second ceramic seal layer, and a third ceramic seal layer, wherein the first ceramic seal layer is located between at least the second and third ceramic seal layers;
wherein the first ceramic seal layer comprises tellurium oxide, the tellurium oxide comprising TeO4 and TeO3, and wherein the first ceramic seal layer comprises more TeO3 than TeO4 by wt. %;
wherein, for at least one location of the seal, the first ceramic seal layer has a first width and the second ceramic seal layer has a second width;
wherein the second width of the second ceramic seal layer is at least about 1 mm greater than the first width of the first ceramic seal layer; and
wherein the first width of the first ceramic seal layer is from about 3-10 mm, and wherein a ratio Wp/W of the second width (Wp) of the second ceramic seal layer to the first width (W) of the first ceramic seal layer is from about 1.2 to 2.2.
