This invention relates to a lap siding product with a manual snap break, and related methods of manufacture and use. More specifically, this invention relates to a prefinished lap siding product that can be manually snapped in half without tools to produce to lap siding boards or panels.
In various embodiments, the present invention comprises a lap siding product with a central face cut, allowing an installer or user to break the lap siding product in half manually, without tools, resulting in two pieces of lap siding. In several embodiments, the lap siding is prefinished (i.e., painted, treated, etc.). The central face cut extends for the length of the product, and its depth is a substantial portion of the thickness of the lap siding product. The central face cut may be the sole central cut, although in several alternative embodiments, a central back cut opposite to the central face cut may be provided. The combination of the face cut and back cut result in an easy manual break that is much cleaner (i.e., with smoother edges, fewer splinters, etc.) than a single cut.
The lap siding product further may comprise a pair of back spacing cuts along the edges of the back face of the product. The back spacing cuts extend the length of the product, and assist in horizontal location of the pieces of lap siding (i.e., after manual breaking) with respect to each other. The back spacing cut of a piece of lap siding is positioned on the bottom of the lap siding, and sits on top of an already-installed piece of lap siding.
The lap siding product also may comprise a pair of machined nail lines on the face of the product, which may extending the length of the product. The nail lines assist in determining locations for nailing the post-break pieces of lap siding during installation.
In various exemplary embodiments, as seen in
The front side comprises a central face (or front side) cut 20, which allows an installer or user to break the lap siding product in half manually, without tools, resulting in two pieces of lap siding 10a, 10b. The central face cut 20 extends for the length of the product, and its depth is a substantial portion (e.g., greater than 50%, 75%, or 80%) of the thickness of the lap siding product. The central face cut 20 may be the sole central cut, although in several alternative embodiments, a central back (back side) cut 22 opposite to the central face (front side) cut 20 may be provided. The central back side cut may be aligned with the central face cut, and has a depth less than the central face cut, and less than half the thickness of the product. In one exemplary embodiment, the central back cut has a depth of from about 5% to about 10% of the thickness of the product. The combination of the face cut and back cut result in an easy manual break that is much cleaner (i.e., with smoother edges, fewer splinters, etc.) than a single cut.
The lap siding product further may comprise a pair of back spacing cuts 40 along the edges of the back face of the product. The back spacing cuts extend the length of the product, extend internally, and assist in horizontal location of the pieces of lap siding (i.e., after manual breaking) with respect to each other during installation, as seen in
The back spacing cuts extend along all or substantially all of the respective edge of the product, and inward for some distance towards the center of the product. The width and depth of the back spacing cuts may vary based on the type of lap siding, and may even vary on the same piece of lap siding product, although, as seen in
The lap siding product also may comprise a pair of machined nail lines 30 on the face of the product, which may extend all or substantially all of the length of the product. The nail lines assist in determining locations for nailing the post-break pieces of lap siding during installation. In one exemplary embodiment, the nail lines are located parallel to the central face cut at a distance less than the width of the back spacing cuts (in one preferable embodiment, about three-quarters to one inch from the central face cut, as seen in
In addition to ease of use in the field during installation, the lap siding product described herein also results in substantial savings and efficiency during manufacture. Instead of line production of prefinished lap siding pieces individually, the present invention allows the production of two prefinished lap siding pieces as a single product, thereby doubling the finishing line output rate, and resulting in an approximately 50% reduction in variable labor and energy costs.
The dimensions of the product, and the resulting pieces of siding, may vary. For example, in the embodiment shown in
Alternatively, in the embodiments shown in
In one embodiment, the method of use of the present invention comprises providing a prefinished lap siding product as described herein, manually snapping the product in half along its length without the use of tools into a first piece 10a and a second piece 10b, nailing (using the nail lines as guides) the first piece into place laterally on a wall or vertical structure with the face side outward and the back spacing cut positioned along the bottom and facing inward, aligning the second piece into an overlapping position above the first piece, and nailing (using the nail lines as guides) the second piece into place overlapping the first piece. A vertical series of overlapping siding pieces can thus be installed, each piece extending laterally, as seen in
In several embodiments, due to the positioning and depth of the central front side cut and the depth of the spacing cuts, any residual “ridge” left in or near the central front side cut when the product is broken or divided into two pieces is located behind the back side of the overlapping lap siding piece when installed, so that the ridge does not interfere with installation. When a central back cut is used (to assist in ease of dividing the product by hand), the resultant ridge is located along the resulting “top” edge of each lap siding piece, but towards the back, so that it remains located behind the back side of the overlapping piece when installed.
Thus, it should be understood that the embodiments and examples described herein have been chosen and described in order to best illustrate the principles of the invention and its practical applications to thereby enable one of ordinary skill in the art to best utilize the invention in various embodiments and with various modifications as are suited for particular uses contemplated. Even though specific embodiments of this invention have been described, they are not to be taken as exhaustive. There are several variations that will be apparent to those skilled in the art.
