Lath is a thin, narrow strip of wood or other material used in construction and building. Traditionally, lath was used to support plaster in walls and ceilings, providing a base for the plaster to adhere to. It is typically made from softwood and can vary in thickness and width, depending on its intended use. In modern construction, lath has evolved to include materials like metal and gypsum board. These alternatives are often used in place of traditional wood lath, especially in drywall systems. The use of lath helps create a stable surface for finishing materials, ensuring durability and structural integrity in buildings.
