According to the Composite Wall Sandwich Panel Roll Forming Machine manufacturers known, the difference as follows:
a. The three fire levels are different. The rock wool sandwich panel is Class A non-combustible, the EPS is B3 grade flammable (not excluding the special flame retardant benzene board), and the polyurethane (edge banding) rock wool board is B1 grade.
b. The insulation performance of the three is different: the polyurethane sandwich panel and the tight sealing performance are good. As for the EPS benzene board and the extruded board, the weight of the two should be distinguished.
c. The waterproof performance of the three is different: polyurethane and EPS are superior to rock wool and glass wool.
