ABSTRACT OF THE DISCLOSURE A prefabricated window system includes a main frame which is fabricated from thermoplastic elements having substantially the same cross-sectional configuration. Windows and a screen are slideably mounted in the main frame. A thermoplastic sill is snap-connected to the bottom portion of the frame and a decorative cover is snap-connected to the top portion. Stop elements, having the same cross-- sectional configuration as the cover element, are snap- connected to the side portions of the frame in order to prevent the windows from being raised or lowered too far. The windows can be pivoted for cleaning, and the frame includes portions which overlap the outer peripheries of the windows to prevent them from inadvertently being rotated outward. These portions also reduce air incursion. A latch is mounted on one window and a keeper which cooperates with the latch is mounted on the other, the keeper being firmly mounted in the window sill by upwardly extending screws. Slots are provided around the periphery of the main frame to accommodate nailing fins which are used during installation of the window system or to receive mullion covers which join adjacent window systems.
