A glazed curtain wall construction for a commercial building is composed of a multiplicity of glass window units and glass panel units which are supported in stacked relationship by a series of vertical columns or mullions. Each unit is rectangular in configuration being composed of a header, a sill and a pair of jambs that connect the header and sill together. The sill of each unit is provided with a downwardly projecting flange which is received within a groove in the header of the next lower unit and the header is provided with an inwardly extending flange that defines a downwardly facing recess which is supported on dumbbells attached to the side surfaces of adjacent mullions. In addition, one jamb of each unit is formed with a vertical flange which is received within a groove in the opposite jamb of the next adjacent unit. To install the unit, the flange on the sill is inserted into the groove in the header of the next lower unit, the unit is then slid sideways to engage the flange on the jamb with the groove in the jamb on the adjacent unit, and the recess on the header is then dropped over the dumbbells to support the header.

1. A curtain wall construction for a building, comprising a plurality of spaced vertical supports, a plurality of generally rectangular exterior units supported by the vertical supports and located outwardly of said vertical supports, each unit being rectangular in shape and including an upper horizontal member, a lower horizontal member; and a pair of vertical jambs connecting the upper horizontal member and lower horizontal member, said units being disposed in stacked and side-by-side relation in said curtain wall, one of said horizontal members having a vertically extending groove and the other of said horizontal members having a vertical flange disposed in said groove to provide a first tongue and groove connection between the lower horizontal member of one unit and the upper horizontal member of an adjacent unit, and abutment means formed on the sides of said vertical supports the upper horizontal member of each unit having a downwardly facing recess engaged with said abutment means to support the upper horizontal member from said vertical supports, a first of jambs having a vertically extending groove and the second of said jambs having a vertically extending flange, the flange on said second jamb being disposed in the groove in the first jamb of the next adjacent unit to provide a second tongue and groove connection between the jambs of said adjacent units. 2. The construction of claim 1, wherein each unit includes an outer glass panel. 3. The construction of claim 2, wherein said glass panel is a window. 4. The construction of claim 1, wherein said upper horizontal member is provided with an inwardly extending extension, said recess being formed in said extension. 5. The construction of claim 1, wherein one jamb of each unit is attached directly to the outer surface of said vertical support. 6. The construction of claim 5, wherein said first jamb has a lip extending substantially the full length of said first jamb, said lip being secured to the outer surface of said vertical support. 7. A curtain wall construction for a building, comprising a plurality of spaced vertical supports, a plurality of generally rectangular exterior units supported by the vertical support and located outwardly of said vertical support, each unit being rectangular in shape and including an upper horizontal member, a lower horizontal member, and a pair of vertical jambs connecting the header and lower horizontal member, said units being disposed in stacked and side-by-side relation in said curtain wall, one of said horizontal members having a vertically extending groove and the other of said horizontal members having a vertical flange disposed in said groove to provide a first tongue and groove connection between the lower horizontal member of one unit and the upper horizontal member of an adjacent unit, an abutment disposed on adjacent vertical supports with said abutments facing each other, an extension extending inwardly from the upper horizontal member and including a generally flat surface resting on said abutments, said extension also including a downwardly extending lip disposed inwardly of said abutments, a first of said jambs having a vertically extending groove and the second of said jambs having a vertically extending flange, the flange on said second jamb being disposed in the groove in the first jamb of the next adjacent unit to provide a second tongue and groove connection between the jambs of said adjacent units. 8. The construction of claim 7, wherein the horizontal length of said extension is less than the distance between adjacent vertical supports to permit the unit to slide horizontally. 9. The construction of claim 7, wherein said upper horizontal member is provided with a trough disposed outwardly of said first tongue and groove connection, and wick means connecting the trough with the exterior to permit drainage of moisture from the trough to the exterior by capilliary action. 10. The construction of claim 7, wherein said horizontal members and said jambs have outer surfaces, said unit including a sheet of glass bonded to said outer surfaces with the outer surface of said glass being free of external stops. 11. The construction of claim 7, and including a strip of ceiling trim secured to the upper horizontal member and to said vertical supports said ceiling trim strip extending inwardly from the unit and having an upwardly extending recess defining a drapery pocket.
