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 cooperates with an exterior transverse wall to define a groove or channel extending laterally inwardly from the outer wall 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.

[ What is claimed is:] [1.] In combination with a building wall having an inner surface and an exterior surface and defining a window opening receiving a frame of a window assembly, said frame comprising an elongated sill member of extruded plastics material and connecting a pair of elongated jamb members of extruded plastics material, each of said sill and jamb members including longitudinally extending and laterally spaced inner and outer walls connected by longitudinally extending transverse walls generally perpendicular to said inner and outer walls, each of said sill and jamb members including an exterior portion projecting outwardly from said exterior surface of said building wall and cooperating with an exterior said transverse wall to define a channel within said exterior portion facing laterally outwardly adjacent said exterior transverse wall and laterally aligned with said exterior surface of said building wall, said channels of said sill and jamb members extending laterally inwardly of said outer walls of said sill and jamb members and laterally inwardly of said window opening, and said channels having substantial depth into said exterior portions of said sill and jamb members from said outer walls to receive edge portions of exterior siding mounted on said exterior surface of said building wall with the edge portions of the siding projecting laterally inwardly of said window opening.
