Abstract
A movable, prefabricated wall panel having a rigid frame. Internal to the rigid frame is a structural acoustical core, consisting of a grid with a plurality of individual cells, each filled with insulation media, such as a loose, discrete insulation such as fiberglass, cellulose, etc. The outer surfaces of the cell grid are covered with a skin or screen mesh for confining the loose discrete insulation. This skin or mesh can be a finished decorative outer cover or an intermediate component that is later covered with a decorative outer cover of fabric or other suitable material. A septum may be provided in the panel in the grid and may be made of a pliable, sound absorbing material. Additional acoustic barrier panels may be sandwiched on either side of the cellular grid.
