An encapsulated fixed window module for a motor vehicle, includes: a fixed window pane having a peripheral edge extending between exterior and interior surfaces; and a trim strip extending along at least a portion of the peripheral edge, the trim strip including a first longitudinal profile of U-shaped cross section. The first profile defines a longitudinal groove configured to receive a guide carried by a movable window pan. The exterior wall of the first profile faces the interior surface and is secured thereto by an over-molded material which does not cover the peripheral edge along the first profile. The exterior wall has a longitudinal edge which is opposite to the lateral wall and which is substantially aligned with the peripheral edge in a plane that is perpendicular to the fixed window pane.
