ABSTRACT:
Multiple pane window glass units of the type having abutting pairs of panes fitted between a head and sill. Particularly an "invisible" mullion assembly comprises of a pair of H-shaped vertical channels extending vertically between head and sill and interposed between the vertical edges of each abutting pair of panes so as to stabilize and support the panes of each pair, together with a T-shaped mullion, having an elongate shank with an outer tip vertically extending between abutting pairs of glass pane edges and a flat inner base extending vertically over abutting inner glass pane edges. An outer gasket is fitted over the end of the T-shaped mullion so as to be compressed between the abutting pairs of outer glass pane edges, while engaging said H-shaped channels. A centering guide positions the Y-shaped mullion at the abutting pairs of inner glass pane edges. Structural silicone caulking is applied in the space between glass and flat inner base of the mullion vertically on both sides and laterally across the joints at the top and bottom. This holds the mullion assembly together forming a box beam and also sealing against air and water leakage past the joint.
