The starter strip 11 (FIGS. 2A and 2B) can have a first fastener hem 13. The first fastener hem 13 may be provided with one or more holes 14 (e.g., such as the elongated slots shown) that are configured to receive one or more first fasteners 15 (e.g., screws, nails, etc.). The starter strip 11 may include a starter flange 17 extending from the first fastener hem 13. As shown in the illustrated embodiment, the starter flange 17 may be substantially perpendicular to the first fastener hem 13. Versions of the starter flange 17 may have a thickness that is substantially similar, or even identical, to that of the first fastener hem 13.
The starter strip 11 also may include a first rib 19 extending therefrom. The first rib 19 can be substantially planar. The first rib 19 can be substantially perpendicular to the starter flange 17. The first rib 19 can be substantially parallel to the first fastener hem 13. Versions of the first rib 19 may have a thickness that is substantially similar, or even identical, to that of the first fastener hem 13 and the starter flange 17.
Versions of the starter strip 11 may include a distal end or tip T (FIG. 2B) on the starter flange 17. The tip T may protrude beyond the first rib 19. The tip T may be chamfered, as shown in FIGS. 2A and 2B. Starter flange 17 can include two shoulders H located on either side of the first rib 19.
Embodiments of the trim assembly 10 may include a fastener flange 21 (FIGS. 3A and 3B). The fastener flange 21 can include a second fastener hem 23. The second fastener hem 23 may be provided with one or more holes 26 (e.g., such as the elongated slots shown) that are configured to receive one or more second fasteners 25. Fasteners 25 may be the same as or different than fasteners 15.
Some embodiments of the fastener flange may include one or more second ribs 27 (e.g., two shown). The second rib 27 can extend from the second fastener hem 23. The second rib 27 can be substantially perpendicular to the second fastener hem 23. Versions of the second rib 27 may have a thickness that is substantially similar, or even identical, to that of the second fastener hem 23.
Embodiments of the trim assembly 10 may further include a trim 31 (FIGS. 4A and 4B). The trim 31 may include a side S with a first recess or slot 33. First slot 33 can be configured to receive the first rib 19. First slot 33 may be chamfered, as shown. The chamfer may be formed on one or both sides of first slot 33. Versions of trim 31 may be mounted to the starter strip 11. In some embodiments, the trim 31 can be mounted to the starter strip 11 without any fasteners.
Versions of side S may or may not be flush on either side of first slot 33. In the version of FIG. 4B, a clearance C is provided between the two portions of side S. When trim 31 is installed, clearance C can help keep the starter strip 11 flush with an end of the trim. Thus, clearance C can help avoid potential gaps between the trim and a window or other location on a building.
In the version of FIG. 1, the two portions of side S are flush such that no clearance is provided therebetween. In this latter version, the two portions of side S abut both shoulders H on starter strip 11. The tip T of starter strip 11 may or may not be flush with the outer surface or front F of trim 31.
Embodiments of trim 31 can include one or more second slots 35. The second slot 35 can be configured to receive the second rib 27. In an embodiment, a plurality of second slots 35 individually and respectively receive a plurality of the second ribs 27. Versions of trim 31 can be mounted to the fastener flange 21. See, e.g., the example of FIG. 6.
Other versions of the trim 31 may further comprise a fastener recess 41 (FIG. 1) configured to accommodate a head of the fastener 15 of the starter strip 11. The fastener recess 41 can be located adjacent the second slot 35, and may comprise a small clearance. In the embodiment of FIG. 1, the recess 41 is contiguous with the second slot 35.

In the embodiment of starter strip 11 shown in phantom in FIG. 4B, the length of its starter flange 17 may be shortened, such that it terminates at first slot 33 as shown. In some versions, starter flange 17 is completely located within the clearance C, such that the back side of starter flange 17 is flush with the side S of trim 31, as shown. Similarly, the first fastener hem 13 of starter strip 11 can reside within fastener recess 41 such that it is flush with back side B.
Some embodiments of the second rib 27 can be non-planar. The second rib 27 can include a lip 29. The lip 29 can be located at a distal end of the second rib 27. The lip 29 can have a shape, such as a hook, a curve, a J-lip, a U-lip, etc. Such a shape can facilitate both frictional and mechanical engagement between the second rib 27 and the second slot 35. Alternately, mechanical fasteners or adhesive may be used to secure the components together.
Embodiments of the lip 29 can accommodate a difference or variance in a width of the second slot 35. For example, if the second slot 35 is relatively narrow, the lip 29 can rotate to provide more engagement with the second slot 35. In the embodiments of a plurality of the second ribs 27, the second ribs 27 can extend in a same direction. The second ribs 27 can have opposed features (e.g., lips 29) at distal ends thereof. The second ribs 27 may be opposed in the sense that they extend at least partially in opposite directions.
In some versions, the trim 31 can be mounted to the fastener flange 21 without any fasteners. The first and second ribs 19, 27 can engage the trim 31 only with friction or interference fit. In some versions, the first rib 19 can engage the trim 31 with friction or interference fit, and the second rib 27 can engage the trim 31 with mechanical and friction or interference fit.
Alternate embodiments of the starter strip 11 and the fastener flange 21 may be configured to engage the trim 31 on surfaces of the trim 31 that are not visible after installation. Versions of the trim 31 can require no fasteners to be installed therethrough. After installation, the first and second fastener hems 13, 23 can be configured to be parallel. Similarly, the first and second fastener hems 13, 23 may be configured to be co-planar after installation. In addition, the first and second fastener hems 13, 23 can be configured to be perpendicular to the starter flange 17 after installation.
In an example, one of the second ribs 27 may be located at an end of the fastener flange 21. In another example, a second one of the second ribs 27 may be located between said one of the second ribs 27 and a fastener hole 26 in the fastener flange 21. Versions of the second rib 27 can be thicker than the first rib 19, or the first rib 19 can be thicker than the second rib 27. The second rib 27 can be longer than the first rib 19, or the first rib 19 can be longer than the second rib 27. In other versions, the second rib 27 and the first rib 19 can be of substantially the same length. Versions of the second fastener hem 23 can be longer than the first fastener hem 17. In other versions, the fastener hem 23 can be shorter than or of substantially the same length as the first fastener hem 17.
Again referring to FIG. 1, the trim 31 may further comprise a thick flange or tab 37. The tab 37 can protrude from trim 31 on a side opposite the first slot 33. Versions of the tab 37 can define a pocket 38. The pocket 38 can be configured to receive a building product 39, such as siding, a widow frame, etc. Some versions of the fastener flange 21 can be configured to face a back B of the trim 31. Some versions of the starter strip 11 can be configured to face the back B and a side S of the trim 31.
Some embodiments of the fastener flange 21 may comprise a metallic material. Embodiments of the starter strip 21 may comprise a polymer. Embodiments of the trim 31 may comprise a polymer. The starter strip 21 and the trim 31 may comprise polyvinylchloride (PVC) or other suitable materials, such as metallic materials. In one embodiment, the trim 31 comprises a cellular PVC.
