Abstract
Abstract 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.
