What is a wall cladding in construction?

Wall cladding in construction refers to the external covering installed over structural walls to impart weatherproofing, insulation, and visual appeal. It is non-structural, meaning it does not bear loads but protects load-bearing substrates. Aluminum wall cladding panels—single-skin or composite—are popular choices for commercial and residential buildings due to their lightweight properties, high strength, and corrosion resistance. Fixed to subframes with concealed clips or fasteners, they create a rainscreen cavity that promotes drainage and airflow. Aluminum’s formability allows for curved and angular designs, while finishes like anodizing or high-performance coatings ensure long-term color retention. In sum, wall cladding is the protective, decorative envelope over which aluminum panels excel.
