A vacuum insulated door structure includes a first wall having a first edge and a barrier layer, a second wall having a second barrier layer and a second edge coupled to the first wall member proximate the first perimetrical edge. The second wall includes at least four inner side walls and a back wall that defines a second wall offset. At least one tubular member extends between the first wall member and the second wall offset, wherein an inner conduit surface of the tubular member provides fluid communication between the first wall outer facing surface and the second wall outer facing surface. A cavity insulation material is disposed within a cavity volume defined between the first and second walls, wherein the cavity volume is hermetically sealed, and wherein the cavity volume includes an at least partial vacuum.
