Door for a Refrigerated Cabinet

A door comprising

• an insulating glass unit having an outer glass lite of predetermined rectangular shape and an inner glass lite of smaller rectangular shape than said outer glass lite sealing secured to said outer glass lite in spaced parallel relation to define a space therebetween;
• a pair of horizontally disposed rails, each said rail having a base, a pair of parallel walls extending perpendicularly of said base, a third wall transverse to one of said pair of parallel walls and extending into the plane of said inner glass lite, an abutment extending from said third wall and abutting said inner glass lite, 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 pair of vertically disposed rails connected to and across said pair of horizontally disposed rails to define a frame, each said vertically disposed rail having a base, a pair of parallel walls extending perpendicularly of said base, a third wall transverse to one of said pair of parallel walls thereof, an abutment extending from said third wall and abutting said inner glass lite, 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.

A door for a refrigerated cabinet comprising

• an insulating 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.
