PANEL CONSTRUCTION Perdue Acoustics’ Diffsorbers, panels, and baffles start with our patented mineral wool core. The front and back are then covered with a random strand fiberglass mat and fabric wrapped. All product cores have a melting point of 1850° F (ASTM E-136), flame spread of 0, smoke developed rating of 0, tensile strength minimum of 2631 lbs./sq. ft. breaking load, compressive resistance of 480 lbs./sq. ft. at 10% compression, and horizontal sag of not more than 1/2” in 4 ft. Panels can be fabricated with our regular edge finish or PVC trimmed edge treatment in a square, radius, or beveled edge. Our baffles are fully fabric wrapped and finished with a flap and grommets at the top edge for hanging.
