Patent attributes
One aspect of the invention features a refrigerated display case door panel assembly. The panel assembly includes a vacuum-insulate glass (VIG) panel assembly, an additional pane of glass, and an electrically conductive coating disposed between the VIG panel assembly and the additional pane of glass. The VIG panel assembly includes two panes of glass bounding a sealed evacuated space between the panes. The additional pane of glass is laminated across one of the panes of glass of the VIG panel assembly to form a refrigerator side of the door. The electrically conductive coating extends across at least a majority of a viewing area of the door and is connected to an electrical conduit for electrically heating the coating to apply heat across the viewing area between the VIG panel assembly and the additional pane of glass.
