Insulated PU Sandwich Panel

PU Sandwich Panel is a high-performance insulated building material composed of two metal sheets bonded to a rigid polyurethane foam core. Designed to meet the requirements of modern industrial and prefabricated construction, PU sandwich panels provide an excellent balance between thermal insulation, mechanical strength, and construction efficiency.

The closed-cell polyurethane core offers outstanding thermal resistance, making the panel an ideal solution for energy-efficient buildings. Compared with traditional insulation materials, PU insulation delivers lower thermal conductivity, enabling thinner panels to achieve superior insulation performance.

PU sandwich panels are widely used in industrial buildings, warehouses, cold storage facilities, prefabricated houses, clean rooms, and commercial structures. Their lightweight nature and modular design significantly reduce construction time and labor costs while ensuring consistent quality and performance.
