However, it has the disadvantage of poor thermal insulation effect. Therefore, other thermal insulation measures need to be taken, which increases the process and cost, and the economy is poor; another composite exterior wall panel filled with polystyrene board or ceramsite concrete in the steel frame , although the wallboard has the functions of heat preservation and load-bearing structure, it has the disadvantages of poor fireproof performance, poisonous gas emission when burning or thick wallboard (ceramsite concrete), and there is also the problem of steel frame cold bridge.
