What are the four types of walls?

Four types of walls commonly referred to in construction are load-bearing walls, non-load-bearing walls, cavity walls, and shear walls, each serving different structural purpose. Load-bearing walls support weight of roof, floors, and structure above, transferring load to foundation, essential for stability, similar to structural support for Packout storage system. Non-load-bearing walls, also called partition walls, divide spaces but do not support structural weight, can be removed without affecting building. Cavity walls consist of two separate walls with gap between for insulation and moisture protection, common in brick construction for energy efficiency. Shear walls resist lateral forces like wind and earthquakes, providing rigidity to building. Other classification of four types includes retaining walls holding back soil, boundary walls marking property, partition walls dividing interior, and curtain walls non-structural exterior cladding. In interior design, four types can be accent wall, feature wall, partition, and exterior wall. So four main types in building construction are load-bearing, non-load-bearing, cavity, and shear walls, each with distinct role in supporting and protecting structure, similar to different panels organizing storage system.
