Shiplap is a type of wooden board commonly used in construction and interior design. It features a distinctive groove cut into the edges, allowing the boards to fit together snugly. This design creates a weather-tight seal, making it popular for both exterior and interior applications, such as siding and wall paneling. Traditionally made from softwoods like pine, shiplap can also be found in various materials, including engineered wood and even metal. Its rustic appearance and versatility have made it a favored choice in farmhouse and modern design styles, adding character and warmth to spaces.
