Method of assembling a display case door

A method of manufacturing a refrigerator display case door, the method comprising the steps of:

• assembling a glass unit including first and second glass panels separated from a third glass panel by spacer assemblies;
• applying sealant between the first and second glass panels and about the spacer assemblies;
• applying a sealing element to a door frame rail element;
• and
• installing a plurality of frame rail elements about the glass unit including inserting a spacing structure of the frame rail element between the first and second glass panels and positioning a rearward wall of each frame rail element adjacent the first glass panel so that the sealing element contacts the first glass panel and forms a void surrounded by the sealing element, the first glass panel and the rearward wall of the frame rail element.

A method of manufacturing a refrigerator display case door, the method comprising the steps of:

• assembling a glass unit including first, second and third glass panels wherein the first and third and wherein the second and third glass panels are separated by respective spacer assemblies;
• applying sealant between the glass panels and about the spacer assemblies;
• and
• applying door rail elements about each side of the glass unit, each door rail element including a spacing structure having projections, a resilient member and a sealing member, wherein the spacing structure is positioned between the first and second glass panels and the projections are inserted into the sealant, the resilient member is placed in contact with a peripheral edge of the first glass panel and the sealing member is placed in contact with a rearward-facing surface of the second glass panel to form a void between the second glass panel, the sealing element and the door rail element.
