Official abstract text for this publication.
A door assembly including a first glass pane, a second glass pane, and a spacer positioned between the first glass pane and the second glass pane such that the first pane and the second pane are separated by the spacer. The door assembly also includes an element that is coupled to the first glass pane and the second glass pane and positioned exterior of the spacer. The spacer and the element cooperate to at least partially define a seal passage, and a clear material is disposed in the seal passage to seal the space, the clear material configured to provide structural support to the assembly.

The invention claimed is: 1 . An assembly comprising: a first glass pane; a second glass pane cooperating with the first glass pane to define a glass assembly; a spacer positioned between the first glass pane and the second glass pane such that the first glass pane and the second glass pane are separated by a space, the spacer formed of a transparent material and extending between the first glass pane and the second glass pane to define at least one side of a cavity filled with a gas, the first glass pane, the second glass pane, and the spacer cooperatively defining a seal passage accessible adjacent to or at a perimeter of the glass assembly; and a clear material disposed in and filling the seal passage at least partially within the spacer, the clear material bonded to the first glass pane, the second glass pane, and the spacer to provide primary structural integrity to the glass assembly. 2 . The assembly of claim 1 , further comprising an element coupled to the first glass pane and the second glass pane, wherein the element encloses the seal passage. 3 . The assembly of claim 2 , wherein the clear material includes liquid urethane that is curable into a clear solid configured to support a load of the assembly and to resist flexing while maintaining a seal of the cavity. 4 . The glass assembly of claim 1 , wherein the spacer has an opening facing the perimeter of the glass assembly, and wherein a portion of the clear material is directed into the opening. 5 . The glass assembly of claim 4 , wherein the spacer is U-shaped and includes sidewalls and a central portion extending between the sidewalls, and wherein the sidewalls define the opening and are attached to the first glass pane and the second glass pane, respectively. 6 . The glass assembly of claim 5 , wherein the spacer includes notches in the sidewalls adjacent corners of the first glass pane and the second glass pane such that the spacer follows a contour of the perimeter. 7 . A door assembly comprising: a first glass pane; a second glass pane; a spacer positioned between the first glass pane and the second glass pane such that the first glass pane and the second glass pane are separated by a space; and an element coupled to the first glass pane and the second glass pane and positioned exterior of the spacer, wherein the spacer and the element cooperate to at least partially define a seal passage, wherein a clear material is disposed in the seal passage at least partially within the spacer and bonded to the first glass pane, the second glass pane, the spacer, and the element to seal the space, and wherein the clear material is curable and is configured to provide primary structural integrity to the door assembly after the clear material has cured. 8 . The door assembly of claim 7 , wherein the spacer is located inward from an outer periphery of the first glass pane and the second glass pane. 9 . The door assembly of claim 7 , wherein the element includes a wiper retainer. 10 . The door assembly of claim 7 , wherein each of the first glass pane and the second glass pane have four sides, and wherein the spacer extends continuously around at least three of the four sides between the first glass pane and the second glass pane. 11 . The door assembly of claim 10 , wherein the spacer has sidewalls and a central portion extending between the sidewalls, and wherein the spacer includes notches in the sidewalls adjacent corners of the first glass pane and the second glass pane. 12 . The door assembly of claim 7 , further comprising a film bonded to the spacer on a face of the spacer facing the clear material, wherein the film has a low moisture vapor transmission rate. 13 . The door assembly of claim 7 , wherein the element is an edge seal that is coupled to and that extends between the first glass pane and the second glass pane to enclose the seal passage between an edge of the first glass pane and the second glass pane, wherein the spacer is formed of a transparent material and defines a monolithic structure extending continuously adjacent an outer perimeter of the first and second glass panes, wherein the first glass pane, the second glass pane, the spacer, and the edge seal cooperatively at least partially define the seal passage extending at least partially around the outer perimeter of the first glass pane and the second glass pane, and wherein the clear material is a polymer disposed in the seal passage and is bonded to the first glass pane, the second glass pane, the spacer, and the edge seal to provide structural integrity to the door assembly. 14 . The door assembly of claim 13 , wherein the edge seal has opposite ends and a wiper gasket channel between the opposite ends, and wherein the opposite ends are respectively adhered to the first glass panel and the second glass panel. 15 . The door assembly of claim 7 , further comprising a top hinge having a top hinge pivot bushing disposed in the clear material to rotatably support the top hinge, and a bottom hinge having a hinge pivot bushing disposed in the clear material to rotatably support the bottom hinge. 16 . The door assembly of claim 7 , wherein the clear material includes a solid material. 17 . The glass assembly of claim 7 , wherein the spacer has an opening facing the perimeter of the glass assembly, and wherein a portion of the clear material is directed into the opening. 18 . A method of manufacturing a door or window, the method comprising: positioning a spacer between a first glass pane and a second glass pane to separate the first glass pane from the second glass pane, the spacer formed of a transparent material, the spacer extending between the first glass pane and the second glass pane and cooperating with the first glass pane and the second glass pane to define at least one side of a cavity fillable with a gas, and the first glass pane, the second glass pane, and the spacer cooperatively defining a seal passage accessible adjacent to or at a perimeter of the first glass pane and the second glass pane; and filling the seal passage with a clear material, the clear material disposed at least partially within the spacer and bonded to the first glass pane, the second glass pane, and the spacer to provide primary structural integrity to the glass assembly while resisting flexing. 19 . The method of claim 18 , wherein the clear material includes urethane that is funneled into the seal passage via a funnel, and wherein air from within the seal passage is vented via a vent line in the funnel while the urethane is funneled into the seal passage. 20 . The method of claim 19 , wherein when the urethane is disposed in the seal passage, a vent line is positioned in a hinge pivot bushing location for mounting a hinge pivot bushing after filling of the seal passage with the urethane.
