An automotive glazing unit includes a glazing and a system for allowing the glazing to be moved translationally with respect to a door of the vehicle. The glazing is curved and laminated and includes an exterior and an interior glass sheet and a plastic sheet between the exterior and interior glass sheets, each sheet having a peripheral edge face. The edge face of the interior glass sheet is located beyond the edge face of the plastic sheet and beyond the edge face of the exterior glass sheet over a portion of the length of the edge face of the interior glass sheet. The edge face of the interior glass sheet includes a protective layer on a portion of the length of that edge face of the interior glass sheet which is located beyond the edge face of the plastic sheet and beyond the edge face of the exterior glass sheet.
