ABSTRACT:
Ceiling panels, formed from metal rods welded together in a grid pattern, are easily installed in suspended subceilings of the type in which panels are supported on bottom flanges of a framework of inverted T-bar rails. In a lower layer of the panel, an array of spaced parallel rods is tied together across each end by an end rod to form a perimeter which fits within a cell opening of the inverted T-barsupport framework, while rods in an adjoining upper layer of the panel, oriented perpendicular to the rod array in the lower layer, are made to extend beyond the lower layer perimeter so as to support the panel, along two opposite panel edges, upon the upper side of bottom flanges of the support frame rails. The perimeter rods in the lower layer in combination with with the exposed portion of the support rail flanges produce the finished effect of a uniform border around each panel. The wire grid panels may be utilized exclusively in a subceiling for an "open plenum" effect or intermixed with conventional solid panels such as acoustical board to provide desired architectural patterns. For noise reduction or avoiding an open plenum view, some or all of the wire grid panels in a subceiling may be overlaid with standard acoustical board. Also, the wire grid panels may be utilized in combination with special rail flange coverings such as the MINIATURE CEILING T-BAR COVER CAP, U.S. Pat. No. 4,848,054 to Blitzer and O'Toole.
