A thin strip of wood is a common building material used in many construction projects. The term can refer to three different types of wood strips: SHIM, LATH, and SLAT. A SHIM is a thin, wedge-shaped piece of wood used to fill small gaps between two objects. A LATH is a thin strip of wood used as a base for plaster or stucco walls. Finally, a SLAT is a thin strip of wood used to make blinds, shutters, or other window coverings.
