1. 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 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 ceramic seal layer and a second ceramic seal layer, wherein the second ceramic seal layer is located at least partially between at least the first ceramic seal layer and the first glass substrate; and
wherein a thermal conductivity of the first ceramic seal layer is less than a thermal conductivity of the first glass substrate, and wherein the thermal conductivity of the first glass substrate is less than a thermal conductivity of the second ceramic seal layer, so that the thermal conductivity of the second ceramic seal layer is greater than the thermal conductivity of the first substrate and greater than the thermal conductivity of the first ceramic seal layer.
