A flexible edge seal for a vacuum insulating glazing unit. The flexible edge seal comprises an elongate first edge seal portion having a substantially constant first cross-section and including a bonding flange at one end, a weld surface at the other end and a first center portion therebetween. An elongate second edge seal portion has a substantially constant second cross-section and includes a bonding flange at one end, a weld surface at the other end and a second center portion therebetween. Each bonding flange includes a substantially flat portion adapted for hermetic bonding to a surface of a different one of a pair of glass panes. The weld surfaces are hermetically joined to one another forming a hermetic seal therebetween. At least one of the first center portion and the second center portion has a convolute cross-section and is asymmetrical to the other center portion.

1. A flexible edge seal for a vacuum insulating glazing unit including a pair of glass panes separated by an insulating gap, the flexible edge seal comprising: an elongate first edge seal portion defining a first longitudinal axis, the first edge seal portion having a substantially constant first cross-section when viewed along the first longitudinal axis, the first cross-section including a bonding flange at one end, a weld surface at the other end and a first center portion therebetween;an elongate second edge seal portion defining a second longitudinal axis substantially parallel to the first longitudinal axis, the second edge seal portion having a substantially constant second cross-section when viewed along the second longitudinal axis, the second cross-section including a bonding flange at one end, a weld surface at the other end and a second center portion therebetween;wherein each bonding flange includes a substantially flat portion adapted for hermetic bonding to a surface of a different one of the pair of glass panes and wherein the respective flat portions of the bonding flanges are disposed substantially parallel to one another and parallel to a plane between the pair of glass panes;wherein the weld surfaces are disposed substantially parallel to one another and parallel to a bonding plane that is oriented substantially perpendicular to the plane between the pair of glass panes, and the weld surfaces are hermetically joined to one another forming a hermetic seal therebetween; andwherein at least one of the first center portion or the second center portion has a convolute cross-section and is asymmetrical, with respect to a plane defined by the center of the insulating gap, to the other center portion. 2. A flexible edge seal in accordance with claim 1, wherein at least one of the first center portion or the second center portion includes multiple convolutes. 3. A flexible edge seal in accordance with claim 1, wherein both the first center portion and the second center portion include at least one convolute. 4. A flexible edge seal in accordance with claim 3, wherein the first center portion includes a different number of convolutes than the second center portion. 5. A flexible edge seal in accordance with claim 3, wherein both the first center portion and the second center portion include multiple convolutes. 6. A flexible edge seal in accordance with claim 5, wherein the number of convolutes on each of the first and second center portions is within the range from two convolutes to six convolutes. 7. A flexible edge seal in accordance with claim 5, wherein the first center portion includes a different number of convolutes than the second center portion. 8. A flexible edge seal in accordance with claim 3, wherein at least one of the convolutes on one of the first and second center portions crosses the plane defined by the center of the insulating gap and at least partially nests within a convolute on the other of the center portions. 9. A flexible edge seal in accordance with claim 1, wherein the upper and lower surfaces of at least one of the bonding flanges define a taper angle with respect to one another such that the bonding flange tapers in thickness in the region adapted for bonding to the pane. 10. A flexible edge seal in accordance with claim 9, wherein the taper angle is within the range from about 2 degrees to about 10 degrees. 11. A vacuum insulating glazing unit comprising: a pair of glass panes separated by an insulating gap and a flexible edge seal, the flexible edge seal including an elongate first edge seal portion defining a first longitudinal axis, the first edge seal portion having a substantially constant first cross-section when viewed along the first longitudinal axis, the first cross-section including a bonding flange at one end, a weld surface at the other end and a first center portion therebetween;an elongate second edge seal portion defining a second longitudinal axis substantially parallel to the first longitudinal axis, the second edge seal portion having a substantially constant second cross-section when viewed along the second longitudinal axis, the second cross-section including a bonding flange at one end, a weld surface at the other end and a second center portion therebetween;each bonding flange including a substantially flat portion hermetically bonded to a surface of a different one of the pair of glass panes, the respective flat portions of the bonding flanges being disposed substantially parallel to one another and parallel to a plane between the pair of glass panes;the weld surfaces being disposed substantially parallel to one another and parallel to a bonding plane that is oriented substantially perpendicular to the plane between the pair of glass panes, and the weld surfaces being hermetically joined to one another forming a hermetic seal therebetween; andat least one of the first center portion or the second center portion having a convolute cross-section and being asymmetrical, with respect to a plane defined by the center of the insulating gap, to the other center portion. 12. A vacuum insulating glazing unit in accordance with claim 11, wherein at least one of the first center portion or the second center portion includes multiple convolutes. 13. A vacuum insulating glazing unit in accordance with claim 11, wherein both the first center portion and the second center portion include at least one convolute. 14. A vacuum insulating glazing unit in accordance with claim 13, wherein the first center portion includes a different number of convolutes than the second center portion. 15. A vacuum insulating glazing unit in accordance with claim 13, wherein the number of convolutes on each of the first and second center portions is within the range from two convolutes to six convolutes. 16. A vacuum insulating glazing unit in accordance with claim 13, wherein at least one of the convolutes on one of the first and second center portions crosses the plane defined by the center of the insulating gap and at least partially nests within a convolute on the other of the center portions. 17. A vacuum insulating glazing unit in accordance with claim 11, wherein the upper and lower surfaces of at least one of the bonding flanges define a taper angle with respect to one another such that the bonding flange tapers in thickness in the region adapted for bonding to the pane.
