A plurality of uniformly spaced pop-up tabs are defined in the horizontal legs of the angle strips directly beneath the open flutes or channels of the metal decking above. Insulation supports are located beneath the ceiling flutes to span the distance between the angle strips. The insulation supports are connected to the vertical legs of the angle strips to form flat, horizontal platforms directly beneath the portions of the flutes that cross the line of studs. Batts of fire-proofing insulation are located atop the insulation supports and are held in position by bending up the pop-up tabs from their original horizontal disposition into a generally vertical orientation.
