Finally, the profiled perforated plate 5 is installed on the front of the flame-retardant layer 9. The profiled perforated plate 5 not only has an aesthetically pleasing decorative effect but also achieves further sound scattering and reduction through its special perforation design.

It not only supports other functional layers such as the sound insulation layer 3 and the flame-retardant layer 9, but also ensures the integrity and durability of the entire wall panel.
