1. A vehicular slider window assembly, the vehicular slider window assembly comprising:
at least one fixed window panel, the at least one fixed window panel defining an opening;
an upper rail and a lower rail attached to the at least one fixed window panel;
a movable window panel that is movable along the upper rail and the lower rail, wherein the movable window panel is movable between a closed position, where the movable window panel covers the opening, and an opened position, where the movable window panel is moved at least partially along the at least one fixed window panel from the closed position;
a perimeter seal attached to a surface of the at least one fixed window panel, wherein the perimeter seal comprises a continuous sealing element that circumscribes the opening and that is configured to seal against a surface of the movable window panel about a periphery of the movable window panel when the movable window panel is in the closed position;
wherein the perimeter seal comprises a plurality of elongated sealing portions including an elongated upper sealing portion, an elongated lower sealing portion, a first elongated side sealing portion and a second elongated side sealing portion, and wherein the elongated sealing portions comprise respective elongated sealing lips disposed along respective base portions;
wherein the respective base portions of the elongated sealing portions have attachment elements disposed therealong, and wherein, with the attachment elements attached to the surface of the at least one fixed window panel, the attachment elements attach a first side of the respective perimeter seal at the surface of the at least one fixed window panel;
wherein the respective base portions of the elongated sealing portions are joined at respective corner regions, and wherein adjacent end regions of the attachment elements are spaced from one another at the respective corner regions such that there is a gap between the adjacent end regions of the respective attachment elements at the respective corner regions;
wherein, with the attachment elements attached to the surface of the at least one fixed window panel, the first side of the perimeter seal faces the surface of the at least one fixed window panel and a second side of the perimeter seal that is opposite the first side faces away from the surface of the at least one fixed window panel and is spaced from the surface of the at least one fixed window panel;
wherein each of the corner regions of the perimeter seal has a respective passageway that is formed through the base portion at the respective corner regions and that extends from the second side of the perimeter seal and terminates at the respective gap, and that is accessible at the second side of the perimeter seal;
wherein, with the attachment elements attached to the surface of the at least one fixed window panel, each of the respective passageways formed through the base portion at the respective corner regions extends from a respective opening at the second side of the perimeter seal and through the base portion at the corner region toward the surface of the at least one fixed window panel, and wherein the respective passageway at each of the corner regions of the perimeter seal fluidly connects the respective opening at the second side of the perimeter seal and the surface of the at least one fixed window panel at the respective gap; and
wherein, with the attachment elements attached to the surface of the at least one fixed window panel, each of the respective gaps is configured to receive a sealant that is dispensed into the gaps via the respective openings and passageways to fill the gaps and to seal the corner regions of the perimeter seal to the at least one fixed window panel.
