1. A refrigerated display case chassis, comprising:
a first insulated panel forming a first wall of the refrigerated display case chassis and comprising:
a first foam layer bounded by a first pair of thermally conductive sheets, and
a first interface edge comprising a first longitudinal notch; and
a second insulated panel forming a second wall of the refrigerated display case chassis and comprising:
a second foam layer bounded by a second pair of thermally conductive sheets, and
a second interface edge comprising a second longitudinal notch corresponding with the first longitudinal notch, wherein the second interface edge mates with the first interface edge to form a thermally insulated joint where, in cross-section, the first longitudinal notch laps the second longitudinal notch such that one sheet of the first pair of thermally conductive sheets terminates at a concave corner of the second longitudinal notch;
wherein the thermally conductive sheets have a greater thermal conductivity than the first or second foam layers.
