The frames are preferably formed from cold rolled steel. A perimeter frame may include first, second and third walls defining an opening or a recess that can be closed by a contact plate. A door for a refrigerated display case may include a glass unit and a forward portion extending inwardly from a perimeter frame edge portion toward an edge of the forward glass pane and a first side portion extends rearwardly to a groove. An insulating member insulates the door rail from the cold area and includes a portion engaging the groove.
