Abstract
A window assembly includes an integrally molded sash, sill, frame and exterior trim unit and wooden interior trim parts fastened to the interior side thereof. An insert such as glazing material is held in place by a wooden interior sash which presses the insert against a peripheral surface of the molded unit. The interior sash is secured in place by screws driven into bosses surrounding the insert. An integral nailing flange extends outward from the molded unit and forms a rigid flashing which is intended to fit against the sheathing of an exterior wall and subsequently covered by the exterior siding. The nailing flange serves to locate the window assembly in the wall, and has holes therein through which nails may be driven to hold the window assembly in place.
Claims18
A window assembly comprising an integrally molded sash, sill, frame and exterior trim unit formed of plastic, wooden interior trim parts fastened to the interior side of said unit, said integrally molded unit including an opening for receiving an insert, said opening being defined at least partially by a perimetric surface integrally formed with said unit and being in a vertical plane against which a marginal portion of the insert may abut, positioning means for accurately locating the insert with respect to said opening and including a lip integrally formed with said sill and sash and extending approximately perpendicular to the plane of said opening, a plurality of bosses extending interiorly of said perimetric surface, and fastening means for securing one of said trim parts to said unit in abutting engagement with said bosses.
A window assembly comprising an integrally molded sash, sill, frame and exterior trim unit formed of plastic, said unit including surface means defining an opening for receiving glazing material, said surface means including a radially inwardly extending, interiorly facing perimetric surface integrally formed with said unit and disposed in a generally vertical plane against which a marginal portion of the glazing material abuts, an interiorly facing wooden sash, a plurality of bosses positioned around the periphery of said opening, said bosses including positioning means for centering said glazing material with respect to said opening, and means for fastening said wooden sash to said unit to clamp said glazing material between said inwardly facing perimetric surface and said wooden sash.
A window assembly comprising an integrally molded sash, sill, frame and exterior trim unit formed of plastic, said unit including an opening for receiving an insert, said opening being defined at least partially by a radially inwardly extending, interiorly facing perimetric surface integrally formed with said unit and being in a vertical plane against which a marginal portion of the insert may abut, an interiorly facing wooden sash, a plurality of bosses extending interiorly of said perimetric surface, and fastening means for fastening said wooden sash to said unit from the interior side of said unit in abutting engagement with said bosses, said insert being clamped between said interiorly facing perimetric surface and said wooden ash.
A window assembly adapted to fit in an opening formed in an exterior wall which includes sheathing and siding applied over the sheathing, said window assembly comprising an integrally molded sash, sill, frame and trim unit, and flange means integrally molded with and extending radially outward from the perimeter of said unit, said flange means being adapted to be received between the sheathing and siding for positioning said window assembly in such opening and for forming a weathertight seal between said window assembly and such wall, said flange means including a radially extending interior surface for flat engagement with the outer surface of the sheathing, and an inwardly tapered exterior surface to permit the siding to fit smoothly over said exterior surface, the outer circumference of said unit having a plurality of substantially axially extending exterior surfaces spaced therearound for positioning said unit within such opening in such exterior wall, and relieved areas beteen said axially extending exterior surfaces to reduce the weight of said insert and save material costs.
