A window assembly for a vehicle includes a window panel comprising inner and outer surfaces terminating at a peripheral edge, An attachment member is adhesively bonded to the window panel at a mounting area of the inner surface by a layer of cured adhesive. The attachment member is a generally S-shaped metallic attachment member having a panel attachment flange, a vehicle attachment flange, and a leg disposed between the flanges and spacing the panel attachment flange from the vehicle attachment flange. The panel attachment flange is configured to conform to the inner surface of the window panel at the mounting area. A fastener at the vehicle attachment flange attaches the vehicle attachment flange to the vehicle to mount the window assembly at the vehicle. The fastener protrudes from the vehicle attachment flange and generally away from the panel attachment flange and the window panel.
