Abstract: A lap siding product with a unique shiplap joint that spaces abutting pieces of siding correctly from each other without installer measurements. The shiplap joint comprises a bottom element and a top element. A lap siding panel or board has a bottom element shiplap joint at one end, and a top elements shiplap joint at the other end. The corresponding ends of two lap siding panels or boards (i.e., one bottom element and one top element) together form the unique shiplap joint of the present invention. One or more drainage channels or grooves help re-direct water from the joint, and at least one of the channels or grooves also provides a visual element for proper spacing. An engineered “stop” on the underside of the top element also helps space the pieces of siding correctly, without requiring measurement during installation.

Abstract: A lap siding or panel siding product with a unique shiplap joint that spaces abutting pieces of lap siding correctly from each other without measurements taken or needed by the installer. The shiplap joint comprises a bottom element and a top element, each extending from the respective piece of lap or panel siding. A set of “tabs” or “hook-tabs” is engineered on or adjacent to the underside of each joint element to space the pieces of lap or panel siding correctly, without requiring measurement during installation. The locations of the tabs or hook-tabs serve as a stop point for placement of the two pieces of lap or panel siding, allowing self-indexing. Post-installation, as the siding pieces expand or elongate length-wise or laterally, the two tabs or hook-tabs move away from each other, thereby allowing expansion and/or elongation without distortion or warping of the siding pieces.

The corresponding ends of two lap siding panels or boards (i.e., one bottom element and one top element) together form the unique shiplap joint of the present invention. An engineered “stop” on the underside of the top element spaces the pieces of siding correctly, without requiring measurement during installation. This also eliminates the need for caulk, pan flashing or joint covers in the joint between the pieces of siding or cladding. The shape of the joint also reduces the intrusion of water, and re-directs water down and out from behind the siding.
