Abstract
A curtain wall assembly composed of horizontal rows of standardized spandrel units mounted to respective floor systems of a building, and horizontal rows of standardized window units arranged alternately with and connected to the rows of spandrel units so as to enclose the spaces between the floor systems. No direct connection of the window units to the floor systems is required. Preferably, for firmly holding the window units against forces normal to the plane of the curtain wall assembly, a reinforcing stud is arranged vertically between any two adjoining window units and rigidly coupled to their opposed side frame members. Each reinforcing stud has its opposite ends anchored respectively to the reinforcing frames of the spandrel units underlying, and to those of the spandrel units overlying, the two window units between which the reinforcing stud lies. The inventive method dictates, first of all, the mounting of the spandrel units to the floor systems, followed by the connection of the window units between the rows of spandrel units.
