Wall types refer to the various constructions used in buildings to provide support, separation, and protection. Common types include load-bearing walls, which support the weight of the structure above, and non-load-bearing walls, which serve primarily as partitions. Other types include curtain walls, which are thin, outer walls that do not support any weight, and retaining walls, designed to hold back soil and prevent erosion. In addition to these, walls can be categorized by their materials, such as brick, concrete, or wood. Each material offers different benefits, like insulation or durability. Understanding wall types is essential for architects and builders to ensure structural integrity and meet design requirements.
