Exterior cladding refers to the protective layer applied to the outside of a building. It serves multiple purposes, including insulation, weather resistance, and aesthetic appeal. Common materials used for cladding include wood, vinyl, metal, and brick, each offering different benefits in terms of durability and maintenance. In addition to enhancing a building's appearance, exterior cladding helps to regulate temperature and protect against moisture. Proper installation is crucial to ensure that the cladding functions effectively and contributes to the overall energy efficiency of the structure. Regular maintenance can extend the lifespan of the cladding and preserve the building's integrity.
