Composite wood exterior panels

It is understood that in China, the energy loss of residential buildings is approximately 50% from walls, 10% from roofs, 25% from doors and windows, 15% from basements and floors. Therefore, choosing thermal insulation materials for walls is a major approach to achieving indoor heat preservation. Plastic wood thermal insulation wall panels are made from raw materials such as polyethylene, polypropylene, polyvinyl chloride, and their copolymers, along with wood powder, plant straw powder, and plant seedshell powders. These materials are processed into hollow panels via extrusion, injection molding, and pressing methods, filled with various insulation materials, and then formed into composite panels. These panels are a new type of wall decorative material that integrates decorative, thermal insulation, soundproofing, and fire-resistant properties. Their thermal insulation effect is 7 degrees higher than that of ordinary boards and 10 degrees higher than that of paint, which can reduce indoor temperature loss and create a warm home environment during the cold winter months.

WPC wall panels are the mainstream thermal insulation material internationally, commonly used in decorative construction for walls, doors, windows, and exteriors, demonstrating their excellent thermal insulation properties. By incorporating eco-friendly thermal insulation materials, WPC wall panels not only provide insulation in winter but also act as heat barriers in summer, making them suitable for both southern and northern climates, meeting our requirements for warmth in winter and coolness in summer. Additionally, they offer sound insulation up to 29 decibels.

Within the enclosed cavity of the plastic wood panel walls, various thermal insulation materials are added to form self-insulating plastic wood boards. These boards can be applied to the exterior walls of steel structures to achieve the thermal insulation properties of the steel structure itself, while also reducing the weight of the building and saving materials. Many types of exterior wall systems can now be used in steel structures. The application of self-insulating plastic wood boards in steel structures not only serves as an exterior wall but also eliminates the need for a separate insulation layer. However, as a new type of exterior wall panel, the self-insulating plastic wood exterior wall system is a new type of exterior wall system that has not been researched or applied in practice before, and many tasks still need to be carried out. These include optimizing the formula of the plastic wood material and strengthening the production process to reduce production costs and improve its durability; optimizing the structural form of the boards to enhance their thermal insulation properties, etc.
