A method of forming a thermally insulated, transparent door for use on a reach-in merchandiser, in which said door has at least two glass lites, and which comprises providing a thermally and electrically insulating spacer member having an outer wall portion and an inner separator body portion, and forming angled notches in the separator body portion to define the respective corners of first and second glass lites; folding the spacer member at the angled notches around one of the glass lites with te body portion in surface contact with the inner glass lite surface and an edge flange of the outer wall portion in engagement with the adjacent marginal edge thereof, and bringing the free ends of the spacer member into juxtaposition and securing them together with locking means for holding the spacer member in assembled peripheral contact around the one glass lite; assembling another glass lite in surface contact with the body portion of the spacer member and in spaced relation with the one glass lite; and molding a non-metallic frame of a preselected polyurethane material to peripherally encase the assembled glass lites and spacer member and create an air-tight seal therebetween.

1. A method of making a transparent reach-in door for a refrigerated product merchandiser, comprising the steps of: providing a thermally and electrically insulating spacer member having an inner central separator body portion with an outer wall forming side sealing flanges on each side of the body portion; applying a locking key member to secure the ends of the spacer member to thereby define a continuous peripheral edging for a glass panel subassembly; forming an unsealed captured glass panel subassembly by: (1) preassembling the spacer member on first and second glass lites with the separator body portion engaging the opposed inner surfaces of the glass lites and the peripheral margins of the lites being captured by the sealing side flanges of the spacer member to form the glass panel subassembly; and (2) applying a moisture barrier material to the outer wall surface of the spacer and locking key members; and molding a non-metal frame to peripherally encase and seal the captured glass panel subassembly to form a reach-in door having opposed vertical inner hinge and outer handle side edges.
