TWO-PIECE HERMETIC SEAL BELLOWS FOR SINGLE-SIDE PLACEMENT ON AN INSULATING GLASS UNIT OR HIGHLY INSULATING VACUUM GLASS UNIT
A vacuum insulating glazing unit (VIGU) comprises a first glass pane and a second glass pane spaced-apart from the first pane to define a cavity therebetween. A first seal member is bonded at a first end to the first glass pane and a second seal member is bonded at a first end to the second glass pane and at a second end to a second end of the first glass pane. At least one of the first seal member and the second seal member has a configuration (when viewed parallel to the panes) including at least one of a toward-pane oriented convolute and an away-from-pane oriented convolute.
1 . A vacuum insulating glazing unit (VIGU) comprising:
a first glass pane;
a second glass pane spaced-apart from the first pane to define a cavity therebetween;
a first seal member bonded at a first end to the first glass pane;
a second seal member bonded at a first end to the second glass pane and at a second end to a second end of the first glass pane;
wherein at least one of the first seal member and the second seal member has a configuration (when viewed parallel to the panes) including at least one of a toward-pane oriented convolute and an away-from-pane oriented convolute.
2 . A VIGU in accordance with claim 1 , wherein both the first seal member and the second seal member each has a configuration (when viewed parallel to the panes) including at least one of a toward-pane oriented convolute and an away-from-pane oriented convolute.
3 . A VIGU in accordance with claim 2 , wherein at least one convolutes of one of the seal members is nested within a like-oriented convolute of the other seal member.
