ABSTRACT:
A system and method is employed to attach panels to vertical and horizontal mullions to form stopless butt-joint curtainwalls. A cap section of a panel engaging hook is attached to the edge of the panel, which typically comprises an insulated glass panel. The hook includes a flange leg portion which abuts a weather pressure gasket and is held in position by a channel shaped retainer clip. A retainer clip is attached to a portion of the mullion by means of a wedge. The a wedge is forced into the space between the retainer clip and the mullion through an aperture in the webb of retainer clip. A screw passes through another aperture in the retainer clip to further fasten the retainer clip to the mullions. The wedge in combination with a cushion located on the opposite side of the retainer clip from the wedge forms a thermal break. Once the assembly pieces are securely attached, the appropriate weather gasketing is provided between the retainer clip and the inside of the insulated glass panel. The panel could be single glazed, metal, granite or multiple or composite panels. Under such circumstances, the shape of the panel engaging hook will vary depending upon the nature of the panel to be engaged, whether the panel is integrally formed, edge attached or back attached.
