Shiplap

Shiplap is a type of wooden board used commonly as exterior siding in the construction of residences, barns, sheds, and outbuildings.

Useful for its strength as a supporting member, and its ability to form a relatively tight seal when lapped, shiplap is usually used as a type of siding for buildings that do not require extensive maintenance and must withstand cold and aggressive climates.

Small doors and shutters such as those found in barns and sheds are often constructed of shiplap cut directly from the walls, with only thin members framing or crossing the back for support.

[2] Installing shiplap horizontally in a room can help carry the eye around the space, making it feel larger.

Rectangular shiplap pieces can be placed in a staggered zig-zag layout to add texture and enhance the size of the room.
