<p>The invention relates to a mullion structure for use in an expanded wall system for a building or a like structure. The mullion structure includes a vertical mullion structure having a structural mullion portion and a mullion half portion. The structural mullion portion is provided with a continuous slot along the entire length thereof, and the mullion portion is provided with an anchor which anchor comprises an insulating anchor portion and a screw portion. The screw portion is received within a tapped hole provided in the insulating anchor portion, and the anchor is adapted to be received in the slot so as to rigidly secure the mullion half portion to the structural half portion. Thus, the anchor provides a thermal break between the mullion half portion and the structural mullion portion. The insulating anchor further includes a second portion provided with an abutment ridge adapted to mate with a corresponding abutment ridge on the mullion half portion so as to prohibit rotational movement of the insulating anchor portion as the screw portion is screwed into the insulating anchor portion.</p> |
