In order to solve the problems that open ceiling design has poor effect on sound absorption,noise reduction and reverberation time control,and also has certain limitations in fire performance,so there are constraints and obstacles in the promotion and application,after comprehensive research and analysis,this paper innovatively developed a prefabricated construction technology of grated ceiling filled with glass fiber cotton,which achieved a triple performance technical breakthrough of sound absorption and noise reduction,fire and heat insulation,and beautiful decoration,and achieved good results in the project construction process and has a good promotion prospect.
