An inner shell of rigid molded plastics material opposes an outer shell of rigid molded plastics material, and the shells have corresponding inwardly projecting adjacent flanges defining a rectangular window opening. A transparent window panel is clamped and sealed against the flanges by a rectangular trim member having a lip portion surrounding the window panel and retained by U-shaped spring clips attached to the outer shell. The inner and outer shells further include opposing contoured rectangular trim portions surrounding the window panel and defining a cavity filled with thermal insulation. The shells also have outwardly projecting flat border portions which surround the contoured trim portions and are spaced by rigid wood frame panels.
