Vacuum insulated panel with optimized seal width(s)

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, a second seal layer, and a third seal layer, wherein the first seal layer is located between at least the second and third seal layers, each of the first, second, and third seals layers comprising ceramic material and overlapping each other;
• 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 second width of the second seal layer is at least about 1 mm greater than the first width of the first seal layer;
• wherein, for the at least one location of the seal, an outer lateral edge of the first seal layer is spaced inwardly from an outer lateral edge of the second seal layer by an offset distance D of at least about 0.5 mm, and an inner lateral edge of the first seal layer is spaced from an inner lateral edge of the second seal layer by an offset distance D of at least about 0.5 mm;
• wherein the first width of the first seal layer is from about 2-20 mm, and wherein a ratio Wp/W of the second width (Wp) of the second seal layer to the first width (W) of the first seal layer is from about 1.2 to 2.2.
