ABSTRACT OF THE DISCLOSURE A window frame assembly for use in a rectangular win- dow opening comprises a preassembled rectangular shaped frame and a locking rail for locking the frame in the opening. The pre- assembled rectangular shaped frame comprises a plurality of frame members, each of which have a composite transverse wall which consists of first and second wall panels which extend trans- versely and are interconnected at first and second side edges to form a substantially rigid structure having a chamber formed inwardly thereof. A first flange projects outwardly from the first wall panel at a first side edge thereof for engagement with one side of a body in which the assembly is to be mounted in use to prevent direct removal from a window opening. A window mount- ing structure is provided on the second wall panel which is adapted to retain at least one window unit within the first frame. A locking channel is formed in and extends longitudinally of and opens at the second side edge of the composite wall to be engageable from the other side of the body in use. A locking rail is provided for each frame member. The locking rail com- prises a longitudinally extending second flange and a longi- tudinally extending locking tongue arranged substantially normal to one another. The locking tongue is adapted to be insertable within the locking rail to dispose the second flange opposite the first flange for engagement with the other side of the body in which the assembly is to be mounted. The locking tongue and locking channel are adapted to interlock to secure the locking tongue within the locking channel in use.
