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, 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;
wherein, for at least one location of the seal, the first seal layer has a first thickness, the second seal layer has a second thickness, and the third seal layer has a third thickness; and
wherein the first thickness is greater than the second thickness and less than the third thickness.
