Abstract
A refrigerator door for a refrigerated display case includes a glass unit having first and second spaced apart glass panels where the first panel has a forward facing surface and the second panel has a rearward facing surface. A spacer element extends between the first and second glass panels. A door rail element includes an external perimeter wall extending from a point adjacent the edge of the first glass panel to a point adjacent the second glass panel. The door rail element also includes a portion which extends within the space between the first and second spaced apart glass panels and a portion which extends externally of the spaced apart glass panels to the perimeter wall. The door rail element further includes a rear wall portion extending inwardly toward the center of the door from the perimeter wall and over a portion of the rearward facing surface of the second glass panel. In one aspect, one or more of the door rail elements may be formed from a composite, for example, resin and glass fibers. A method of assembling the door is also disclosed, which may include assembling the glass unit and applying a sealant between the first and second glass panels.
