shiplap

Over this paper place any kind of boards that the fancy of the builder may dictate, as clapboards, shiplap, or drop-siding.

Through a single shiplap partition rose a rumble of masculine talk, where the logging crew loafed in their bunkhouse.

His house was rudely put together, shingle-roofed and walled with shiplap boards that gave out strong resinous odors.

They evidently come in from the outside between the logs and the shiplap to the loft above.

The walls will be of shiplap, covered with matched siding, with tarpaper between.
