A curtain wall assembly composed of horizontal rows of prefabricated spandrel units mounted to respective floor systems of a building, and horizontal rows of prefabricated window units arranged alternately with and connected to the rows of spandrel units so as to enclose the open spaces between the floor systems. Each of the spandrel units and window units comprises a panel or panels and a generally rectangular frame supporting the panel or panels. Each spandrel unit further has an interior reinforcing frame through which it is coupled to the floor system. 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. No direct connection of the window units to the floor systems is required.
