A window frame includes tubular sill, head and jamb members of extruded plastics material, and each member has laterally spaced inner and outer walls integrally connected by laterally extending transverse walls. A nailing flange projects laterally outwardly from each outer wall for securing the frame within a wall opening, and each frame member has an integral exterior portion projecting outwardly from the corresponding nailing flanges. The exterior portion of each frame member includes a laterally outwardly projecting double wall tubular flange which cooperates to define a groove or channel for receiving the edge portion of exterior siding. Narrower frame members also have cavities within the interior transverse walls for receiving the edge portions of interior wood sill, head and jamb extenders. In one embodiment, the double wall tubular flange snap-fits onto each frame member so that the flange may be omitted or later attached in the field.
