What is the purpose of cladding material on a building?

The purpose of cladding material on a building is to act as the outer layer covering. Cladding serves several functions, primarily protecting the structure from the elements and providing a finished exterior appearance. This protective layer helps shield the underlying structure from weather conditions, such as rain, wind, and sunlight, while also contributing to the building's overall aesthetic by allowing for various finishes, textures, and colors.

While cladding can provide insulation and enhance energy efficiency, its primary role is to be the external skin or facade of a building. This outer layer can also contribute to the structural integrity by distributing loads and enhancing resistance against environmental factors, but those roles are secondary to its main function as the outer covering.
