Polyurethane composite panels, also known as PU sandwich panels, are high-strength, energy-efficient, and environmentally friendly building materials made of upper and lower metal sheets with a polyurethane foam core. They are used for the roofs and walls of industrial and residential buildings such as factories, shopping malls, and villas.
Advantages of Polyurethane Composite Panels
1，Thermal Insulation and Soundproofing
Polyurethane composite panels offer excellent thermal insulation and soundproofing performance. With a low density and low thermal conductivity, 5 cm thick polyurethane panels provide insulation equivalent to 1 m thick concrete. Additionally, polyurethane is non-combustible.
2，Roof Panel Benefits
Polyurethane roof panels feature concealed fasteners and a unique waterproof groove design, effectively preventing water leakage.
3，Wall Panel Benefits
The surface of polyurethane wall panels has no exposed screws, enhancing the aesthetic appearance of building walls. They also possess high bending strength, reducing reliance on auxiliary steel structures.
4，Eco-Friendly
Made from bio-based raw materials, polyurethane composite panels contain no harmful substances restricted or prohibited by national regulations, ensuring environmental friendliness.
