China External Building Cladding Material

Our leader fiber cement external siding is better material for exterior decoration. Many kinds surface pattern can be chosen according to your project. Its most advantage is durable. Our leader exterior wall panel can be live in any temperature from -40C to + 42C.
Exterior wall wood fiber cement cladding is the top grade decoration exterior wall panel with functionality adn decoration performance. The cement is as sticky component, so our board is durable and weatherable just as cement, which has also good performance withfirproof, waterproof, anti-month; The wood fiber also help the board with woody flexibility, lightweight, heat preservation, anti freeze, sound insulation, easily ficing etc. Which is very suitable for wood frame, steel structure or concerete commercial and residential buildings, our product is also a new enironmnet-friendly construction decoration material promoted by the state.
