Shiplap Timber Modle
Shiplap is a type of wooden board used commonly
in the construction of barns, sheds outbuildings and inexpensive or seasonal
homes. It is either rough-sawn 1" or milled 3/4" pine or similarly
inexpensive wood between 3" and 10" wide with a 3/8" - 1/2"
rabbet on opposite sides of each end. The rabbet allows the boards to overlap
in this area. The profile of each board partially overlaps that of the board
next to it creating a channel that gives shadow line effects, provides
excellent weather protection and allows for dimensional movement. 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. Rough-sawn shiplap is attached vertically in post and beam
construction, usually with 6d-8d common nails, while milled versions, providing
a tighter seal, are more commonly placed horizontally, more suited to
two-by-four frame construction. 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. Shiplap is
also used indoors for the rough or rustic look that it creates when used as
paneling or a covering for a wall or ceiling. Shiplap is often used to describe
any rabbeted siding material that overlaps in a similar fashion.
