Wall systems are structural components used in buildings to create enclosures and support loads. They can be made from various materials, including concrete, wood, and steel, and are designed to provide stability, insulation, and protection from the elements. Wall systems can be categorized into different types, such as load-bearing walls and non-load-bearing walls, depending on their function in the overall structure. In addition to their structural role, wall systems also contribute to a building's energy efficiency and aesthetic appeal. They can incorporate features like insulation for temperature control and finishes for visual enhancement. Modern wall systems may also include windows and doors to allow natural light and access while maintaining the integrity of the building.
