Vehicle wall with hinged window

The side or rear panel (14) of the vehicle or caravan is made of a suitable synthetic material (16) with a wooden area (18) surrounding the opening (20) for the insertion of a window (12). A step (26, 28, 30, 32) is cut into the wood (18), matching a step (38, 40, 42) provided in the metal frame (22) surrounding the double glazed window (56, 58). The edges of the panes (56, 58) are accommodated in the recess formed by the step (38, 40, 42), resulting in a plane surface, not affected by the wind when driving.
