Abstract
A vacuum insulating panel may include: 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 a pressure less than atmospheric pressure; a seal provided between at least the first and second substrates, the seal including a first ceramic seal layer and a second ceramic seal layer, wherein the second ceramic seal layer is located between at least the first ceramic seal layer and the first glass substrate; and wherein one or more of: (i) a thermal (TC) conductivity of the first ceramic seal layer is be 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; (ii) a thermal conductivity of the second ceramic seal layer is greater than a thermal conductivity of the first ceramic seal layer; and/or (iii) a ratio TDp1/TDg, where TDp1 repres…
