Abstract:
1. An improved acoustic ceiling panel for use with a suspended ceiling frame system, the suspended ceiling frame system having a plurality of T-bars and a plurality of cross T-bars, each of the T-bars having horizontal surfaces for supporting adjacent ceiling panels and having vertical surfaces for separating adjacent ceiling panels, the improved acoustic ceiling panel, comprising: a sound absorbing member defined by a first and second face surface and a plurality of peripheral edges; said first surface of said sound absorbing member being supported by said horizontal surfaces of the plurality of T-bars and the plurality of cross T-bars with said plurality of peripheral edges of said sound absorbing member located adjacent the vertical surfaces of the plurality of T-bars and the plurality of cross T-bars; a sound blocking member defined by a first and second face surface and a plurality of peripheral edges; said first face surface of said sound blocking member being secured relative to said second face surface of said sound absorbing member for blocking the transmission of sound therethrough; at least one of said peripheral edges of said sound blocking member extending beyond a peripheral edge of said sound absorbing member for defining an overhang; and said overhang extending over the vertical surface of a respective T-bar for overlapping a peripheral edge of an adjacent sound blocking member for providing a continuous sound blocking member.
