An exterior wall is the outer wall of a building that forms its outer surface and provides protection from weather elements such as rain, wind, and snow. These walls also help define the building's shape and appearance while providing insulation and security. Exterior walls can be made from various materials, including brick, stone, wood, or concrete, and may include windows and doors for access and natural light. They play a significant role in a building's energy efficiency, comfort, and overall aesthetic appeal.
