Abstract
A readily removable and replaceable acoustical pad for an interior space dividing system of the type having horizontal and vertical frames forming generally rectangular pad receiving windows with the upper horizontal frame member of each window having a depending flange or flanges forming a tongue, each pad having an upwardly opening central groove along the top edge adapted to mate with the tongue whereby the pad may be inserted in the window by first mating the groove with the tongue and then pivoting the pad to a vertical position into a snug fit in the window. The pad is preferably foam and fabric covered to deform along the bottom, vertical and groove spaced top edges to obtain the snug fit, and includes a frame, the upper element of which forms a V-shape groove. A metal septum is centrally positioned in the frame with fiberglass pads on each side, within the frame. Options include one half size foam covers with tack boards either directly fabric covered or with a one quarter size foam cover option. The fabric completely encases the pad and the free edges thereof are tucked into and secured to the inside of the frame forming the top groove.
