What is WPC Exterior Wall Cladding?
WPC (Wood-Plastic Composite) exterior wall cladding is an advanced composite building material crafted by combining wood fibers or wood flour with thermoplastic polymers (HDPE, PVC) and performance additives. This fusion yields a robust, weatherproof, and visually striking alternative to traditional cladding materials such as timber, steel, fibre cement and metal. WPC cladding is engineered for wpc outdoor wall cladding applications—offering notable advantages in moisture resistance, UV stability, fade resistance, impact absorption, and insulation.
