Abstract
A modular acoustical panel for use in separating and dividing an interior space includes a generally hollow, open frame member having a generally rectangular wall portion which surrounds and defines a core-receiving space. A modular septum which is arranged with a center partition offset so as to have a surrounding wall and surrounding flange is preassembled with two layers of insulating material on opposite sides of the center portion of the offset partition. The modular septum is able to be assembled off-line and brought to the point of final assembly into the frame. The center portion of the modular septum and the two layers of insulating material are inserted into the core-receiving space and the outer flange of the partition attaches directly to the outer surface of the frame on one side. A spacer is provided on the opposite side to make the thickness symmetrical and thus account for the thickness of the flange portion. When the assembly of the modular septum to the frame member is completed, the entire assembly is covered with exterior material applied to both sides of the panel.
