Abstract: A louver for directing airflow in a refrigerated display case, and a refrigerated display case employing a louver. In some embodiments, the louver includes a plurality of fins positioned to define a plurality of channels therebetween through which airflow can be directed substantially in a first direction. Each fin can be elongated in a second direction substantially orthogonal to the first direction to define a length. Each fin can include an inlet end and an outlet end in a cross-section taken along the length. The louver can further include a curved inlet profile defined by the inlet ends of the plurality of fins.

Abstract: A glass assembly for a refrigerated display case. In some embodiments, the glass assembly includes a first pane having a first edge, a second pane substantially parallel to the first pane having a second edge substantially aligned with the first edge, and a third pane substantially parallel with the first pane and the second pane. The third pane includes a third edge offset from the second edge and defines a step in the glass assembly.
