Cladding is an outer covering for buildings made from materials like metal, bois, and composites, serving to protect from weather and enhance aesthetics, with the added benefits of insulation and improved thermal performance. Veneer, in contrast, is a thin layer of natural materials like wood or stone used primarily for interior design to enhance visual and tactile appeal. Cladding is selected for its durability and protective qualities, whereas veneers are valued for their aesthetic and design contributions.
