Provided are a glass panel unit and a method for manufacturing the glass panel unit, both of which are designed to overcome the problem of poor handleability of known glass panel units with no through holes. A glass panel unit includes a first panel, a second panel, a seal, and a boundary wall. The seal has a frame shape and hermetically bonds respective peripheral edge portions of the first panel and the second panel. The boundary wall partitions an internal space into a first space as a hermetically sealed evacuated space and a second space spatially separated from the first space. The first panel has a first through hole provided through a portion, corresponding to the second space, of the first panel. The second panel has a second through hole provided through a portion, corresponding to the second space and facing the first through hole, of the second panel.

Disclosed are integrated sliding glass panel bumper assemblies, frameless sliding glass panel systems that include one or more of the integrated sliding glass panel bumper assemblies, methods for installing the integrated sliding glass panel bumper assemblies, and methods for retrofitting a frameless sliding glass panel system with one or more of the integrated sliding glass panel bumper assemblies.
