PU panel is a type of building material that consists of two layers of metal sheets or other materials with a layer of polyurethane foam in between. The polyurethane foam acts as an insulator, providing thermal insulation for the building. The metal sheets provide structural support and protection against weather and other external elements. PU sandwich panels are commonly used in the construction of walls, roofs, and ceilings in industrial and commercial buildings, as well as residential homes. They are lightweight, easy to install, and have good fire resistance and sound insulation properties.Insulation performance is better than EPS sandwich panel.

PU sandwich panel is a type of composite panel made up of a polyurethane foam core sandwiched between two metal sheets. The metal sheets can be made of aluminum, steel, or other metals. The polyurethane foam core provides excellent insulation properties, making it ideal for use in applications where thermal insulation is required. PU sandwich panels are commonly used in the construction industry for roofing, wall cladding, and cold storage applications. They are lightweight, easy to install, and have a high strength-to-weight ratio, making them a popular choice for building projects.
