A floor/ceiling 10 has downwardly extending ribs ( 14 ) separated by downwardly opening channels ( 16 ). The floor/ceiling member ( 10 ) sits down on a horizontal header ( 32 ) that is on top of a building wall that extends perpendicular to the ribs ( 14 ) and the channels ( 16 ). A preformed wall panel ( 24 ) has a lower strip portion ( 26 ) that is connected to a side flange ( 36 ) on the header ( 32 ). Preformed wall panel ( 24 ) has upwardly directed peaks ( 28 ) and upwardly opening valleys ( 30 ). The peaks ( 28 ) are sized and shaped to snuggly fit within the ceiling channels ( 16 ). The valleys ( 30 ) are sized and shaped to snuggly receive the ribs ( 14 ) when the peaks ( 28 ) are in the channels ( 16 ). A continuous lower strip portion of the preformed wall panel ( 24 ) is connected to the flange ( 36 ) of the header ( 32 ), below the ribs ( 14 ). The peaks ( 28 ) extend into and block or close off the channel openings formed in and by the channel ( 16 ) above the web ( 38 ).
