ABSTRACT:
A plastic window assembly is adapted to be mounted in an opening defined by a structure. The plastic window assembly is oval-shaped with a decorative plastic window muntin. A plastic frame supports parallel window panes. The window muntin is disposed between the parallel window panes. Flat surfaces of the window muntin have a first edge and a second edge and include a ridge disposed along each of the edges. Marring of the window panes is prevented because the ridge provides for line contact between the window muntin and the window panes. The window muntin may also be integrally molded to a plastic pane disposed between the parallel panes of glass. The plastic pane includes a surface texture that simulates frosted glass. The plastic window assembly includes a plurality of liner panels that extend through the opening from an interior of the structure. The window assembly includes a flange having aperture throughwhich fasteners are inserted to secure the window assembly to the structure. An exterior trim ring attaches to the outside of the window assembly and over siding on the structure. An interior trim ring attaches to a flange in the liner panel to give a finished appearance. All exposed surfaces include a surface texture that simulates wood grain.
