The Difference Between Shiplap and Overlap

What is Shiplap and Overlap?

Shiplap is a term used to describe a type of wooden board used commonly in the construction of sheds and outbuilding. 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 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. Shiplap is also used indoors for the rough or rustic look that it creates when used as panelling or a covering for a wall or ceiling. Shiplap is often used to describe any rebated siding material that overlaps in a similar fashion.

Overlap refers to a more traditional method of finishing a shed or outdoor building. It is a simple yet aesthetically pleasing finishing. The overlap technique comprises of wooden boards. Each board has square cut edges and is ‘overlapped’ onto the adjacent edge of the next board. The boards are then nailed to vertical bearers. This is an economical method of manufacture as the boards need minimal preparation. The technique is simpler way to manufacture a sidewall in comparison to shiplap. Two major advantages of Overlap is the cost effective side as well as the aesthetically pleasing rustic look.
