PU (Polyurthane) is known as the best heat insulation material in the world at present. The sandwich panel which composited two faces prepainted steel sheet and one layer of PU board also has a great perforance on heat insulation. So the PU sandwich panel is widely used in projects which required excellent cold or heat insulation. Like cold storage warehouse,
