Abstract

A vehicular window assembly such as a front windshield in the preferred embodiment includes a window panel and a casing molded on a first portion of the peripheral edge of the window panel. A trim strip covers and finishes portions of the periphery of the assembly. The trim strip extends continuously without interruption from the window panel edge to a mounting rib on the casing through a transition area. The trim continues along the casing and is spaced from the window panel edge. When installed, the casing and trim strip fill the space between the window panel and vehicle body to reduce wind noise when the vehicle is moving and improve weather sealing around the window.
