DETAILED DESCRIPTION OF THE INVENTION

[0016] The replacement window jamb extender 100 is an extruded one piece element with a built-in flange and J-channel containing a self-adhesive seal tape 104 on the flange to replace a new construction window. FIG. 1A exemplarily illustrates a front perspective view of the replacement window jamb extender 100, FIG. 1B exemplarily illustrates a side sectional view of the replacement window jamb extender 100, and FIG. 1C exemplarily illustrates a side view the replacement window jamb extender 100 made of wood. The replacement window jamb extender 100 is the solution for replacing new construction type windows with a more efficient replacement window. As per the construction, the replacement window jamb extender 100 accommodates a frame of a replacement window of a predefined geometry within an existing depth of a jamb 106 as shown in FIG. 2. The replacement window jamb extender 100 comprises a substantially L-shaped frame 102 and a flange with self-adhering and self-sealing tape 104. The replacement window jamb extender 100 is configured to be molded as a one-piece vinyl or similar building material product to be either of chambered or of solid construction, and the product can be molded in multiple colors, and can be modified into woodgrain or laminate color coatings, or a matte finish.

[0017] The replacement window jamb extender 100 can accommodate any common size or depth of any replacement window frame without concern for the existing depth of the house jamb 106, thickness of the existing new construction window, or the mounting depth of the jamb 106. The replacement window jamb extender 100 produces a clean, quickly and efficiently installable, and a readymade finished product compared to the other methods or devices available in the market. When installed, the replacement window jamb extender 100 allows a replacement window to utilize the same mounting depth of the jamb 106, and it does not require extensive finish work as it has an accommodating integral J-channel for the existing cladding, and comprises a self-adhering and self-sealing flange 104 which slides behind existing cladding. To the interior, depending on the existing window and other building materials, minimal to no interior work is required as the same mounting depth of the jamb 106 is used and no drywall or wood trim work is necessary.

[0018] FIG. 2 exemplarily illustrates a side view the replacement window jamb extender 100 being attached to the stud member. As disclosed in FIGS. 1A-1B, the replacement window jamb extender 100 is configured to accommodate the frame of a replacement window of a predefined geometry within an existing depth of a jamb 106 in an already existing construction. The replacement window jamb extender 100 includes the L-shaped frame 102 and a flange with self-adhering and self-sealing tape 104. The L-shaped frame 102 is configured to be fixedly attached to a window slot 108 on a wall 110, where an inner side 102a of the L-shaped frame 102 is configured to accommodate the frame of the replacement window within the existing depth of the jamb mounting area 106. The flange 104 extends from an outer side 102b of the L-shaped frame 102, and the flange 104 is configured to fixedly attach the L-shaped frame 102 on an outer panel 112 attached on an outer side of the wall 110. The outer panel 112 is, for example, 0.5-inch ply wood, and the wall 110 is 4.5 inches in thickness overall including the outer panel 112 and interior drywall section 114.

[0019] In an embodiment, a bottom section 102c of the L-shaped frame 102 is configured to be positioned up to a drywall section 114 extending from an inner side of the wall 110. The drywall section 114, for example, about 0.5 inches, found in the inner portion of walls 110 extend towards the window slot 108 to receive the bottom section 102c of the L-shaped frame 102. The wall 110 terminates at a nominal 2 inches×4-inches stud member 116 and the drywall section 114 extends over the stud member 116 to define the jamb mounting area 106. In an embodiment, the replacement window jamb extender 100 further comprises an integral J-channel fin 118 positioned proximal to the flange 104 and extending from the outer side 102b of the L-shaped frame 102. In an embodiment, the J-channel fin 118 forms a groove between the flange 104 and the J-channel fin 118 which accepts the existing exterior cladding. The integral extruded exterior stop 102d is configured to eliminate additional exterior trim work that might be required during the installation or attachment of the replacement window.

[0020] In an embodiment, the replacement window jamb extender 100 further comprises a flange 104 attached to the L-shaped frame 102, wherein the flange 104 is self-adhering and self-sealing to allow the flange 104 to be positioned behind an existing cladding covering the outer side of the wall 110. In an embodiment, the replacement window jamb extender 100 further comprises a counter sunk screw 120 configured to attach the L-shaped frame 102 to the wall stud member 116, where the counter sunk screw 120 is inserted from the inner side 102a of the L-shaped frame 102. The counter sunk screw 120 is screwed to the stud member 116 to increase the stability of the replacement window jamb extender 100 over the wall 110, stud member 116 and the outer panel 112.

[0021] The installation of the replacement window jamb extender 100 comprises different steps. Primarily, the user needs to remove the old window unit ensuring all nails and debris is removed from the space surrounding the window slot 108. The remaining siding nails are recommended to be removed using a reciprocating saw to obtain a clean surface for the installation of the replacement window jamb extender 100. The previous J-channel attached to the old window unit must be removed, and a sealant is applied to the interior jamb 106 and drywall exterior edge 114. Now, the replacement window jamb extender 100 is cut as per the required dimension, and top gasket seal and side gasket seal are applied.

[0022] In other words, the distance between the jambs 106 is measured for the top header and the replacement window jamb extender 100 is cut at an angle of 45 degrees on each side. Then the sealant is applied to the jamb 106 and the drywall exterior edge 114. The sealant can be further applied on a shim if necessary. Pre-drilling of the outside corners is performed and the sealant is applied to the holes and the screws, for example, counter sunk screw 120. Now the measuring tape is removed and the replacement window jamb extender 100 is secured with the counter sunk screw 120. Now, the side pieces are measured, as well as top header to sill portion, and then the replacement window jamb extender 100 is cut at 45 degree angles in preparation for a miter joint. Now the tape is removed, and the assembly of the replacement window jamb extender 100 is leveled and secured, where a gasket seal or sealant is applied to the corners.

[0023] The bottom piece of the replacement window jamb extender 100 is measured, and this bottom sill piece is of similar length as that of the top header piece. The bottom piece of the replacement window jamb extender 100 is slid into place and secured with screws. However, the siding may have to be removed and re-applied to properly fit. Finally, the 4 pre-drilled outside corners are filled with the gasket seal to finish the installation of the replacement window jamb extender 100.

[0024] FIG. 3 exemplarily illustrates a front view of the replacement window jamb extender 100. Here, one of the outside corners of the assembled replacement window jamb extender 100 is shown. The integral extruded J-channel fin 118 and the integral flange 104, both which extend from the L-shaped frame 102 is shown. The assembly of the replacement window jamb extender 100 as described above, provides a chambered appearance to the viewer. The counter sunk screw 120 as shown here, keeps the replacement window jamb extender 100 secured to the stud member 116 as shown in FIG. 2. The integral flange 104 would not be visible at completion as it is covered by the exterior cladding.
