A bead having a plurality of protrusions is connected to the mullion in a lengthwise direction thereof, and supports the interior trim member. A plurality of retainers are insertable into notches in the mullions, the beads or the rails for removably retaining glazing infill components (i.e. panels, windows, doors) in the curtain wall.
