Shiplap is made out of inexpensive wood such as pine, and has traditionally been used in the construction of barns, sheds, outbuildings, or seasonal homes. It is either rough-sawn 1" or milled 3/4" wood that is between 3" and 10" wide with a 3/8" rabbet that lets the boards overlap in this area.
The profile of each board partially overlaps. When they overlap they create a line effects. When used in an outdoor application the way that the boards fit together provides weather protection. The rabbet grove allows for the wood to swell and move.
