ABSTRACT:
The invention provides a thermal break configuration in a flush glazed, two-piece mullion which permits a reduced face dimension without reducing the depth of the glazing channels of the mullion. The invention is directed to a thermal break segmented filler assembly for the shallow glazing pocket in narrow flush glazed two-piece framing for curtainwalls, storefronts, and the like. The two-piece mullions have a major portion and a filler portion, both of which are extruded profiles. The filler assembly incorporates a thin thermal break which makes it possible to reduce the mullion face dimension and still provide a glazing pocket depth equal to that of conventional flush glazed thermal framing. The thin thermal break of the filler assembly includes a plastic channel extrusion having rigid upturned legs with relatively soft barbs which engage channels in aluminum extrusion filler halves. The thermal break filler element is snap fit onto and between the filler halves to form a three-piece filler assembly.
