. different fire rating: Yanmian sandwich panels for the A-level, EPS for the B3-class, polyurethane B1 level. . different insulation properties: the three polyurethane sandwich panels the best. . waterproof performance is different: the three polyurethane and EPS better than rock wool. . the density of different: rock wool bulk density is generally 120KG / cubic meter, EPS is generally . polyurethane is generally 40. In short, the overall performance of polyurethane sandwich panels for the best, is the best choice for steel structure, Have a number.
