Butt Joint

A butt joint is a type of joint where the ends of two building materials, such as boards or metal sheets, are joined together in a straight line without overlapping. The materials are typically butted together and fastened with adhesive, nails, screws, or other types of mechanical fasteners. Butt joints can be reinforced with additional support, such as metal plates or wood splines, to increase strength and stability. In some cases, butt joints may also be sealed with a caulk or other type of sealant to prevent moisture or air infiltration.
