ABSTRACT:
A non-operable window frame assembly comprising two frame sections, each of which slips into a rectangular hole in a wall from opposite sides of the wall; the wire glass or fire resistant glazing material is held in place by means of four pieces of square sugar molding screwed in from the top of the molding; the screws go through both sections of the window frame assembly; holding the entire assemblage in place without the need for anchor clips, making the window frame assembly self anchoring. The size of the glazing material is up to 36".times.36". The height of the square molding is a minimum of one inch, making the maximum size of the exposed glazing material 34".times.34". The entire assemblage comprising the window frame assembly and wire glass or fire resistant glazing material meets Underwriters Laboratories standards with a fire rating "C" label (45 minutes). The miters of the two from sections are continuously welded at the corners. The window frame assembly can be used for both interior and exterior walls of varying widths. For installations in an exterior wall, the glazing material can be replaced if it is broken from the inside of the building without the need for scaffolding or ladders on the exterior of the structure. The window frame assembly can be manufactured with or without a drywall return.
