Door for a refrigerated cabinet
First Claim
1. A door for a refrigerated cabinet comprisingan insulated glass unit having an outer glass lite of predetermined rectangular shape with an electrically conductive coating thereon, an inner glass lite of smaller rectangular shape than said outer glass lite and an intermediate glass lite disposed in spaced relation between said outer glass lite and said inner glass lite;
- a plurality of aluminum rails defining a frame about said insulated glass unit, each said rail having a base, a pair of parallel walls extending perpendicularly of said base and a flange extending from said base in parallel to said pair of walls and defining a recess with one of said walls receiving an edge of said outer glass lite in sealed relation therein; and
a plurality of plastic strips, each said plastic strip being disposed between said outer glass lite and one of said pair of parallel walls of a respective rail to electrically insulate said electrically conductive coating on said outer glass lite from said one of said pair of parallel walls of said respective rail.

Abstract
The door is made with a triple-lite insulated glass unit and a frame of aluminum rails. The insulated glass unit has a stepped cross-section with the outer glass lite being larger than the inner glass lites. An opaque non-conductive ceramic frit forms a rectangularly shaped border to mask the mounting of the inner glass lite(s). An electrically conductive coating on the outer glass lite is insulated from the aluminum rails of the frame by a plastic strip disposed between the outer glass lite and each rail.
