ABSTRACT OF THE DISCLOSURE A plurality of standardized curtain wall units of rectan- gular shape are arrange in rows and columns, with a predetermined gap between the opposed side frame members of every two horizontal- ly adjoining curtain wall units. For closing the gap so as to allow relative displacement of the individual curtain wall units in their own plane, a sealing band of elestic matrial has its lateral marginal edge portions engaged in a pair of opposed mount- ing grooves in the opposed side frame members of every two hori- zontally adjoining curtain wall units. The sealing band has a width less than the distance between the bottoms of the pair of opposed mounting grooves in which the sealing band is engaged. Thus assembled unit type curtain wall assembly has a room tempera- ture control function, with passageway for conditioning air and hot or cold water extending longitudinally through the side frame members of each curtain wall unit. The gap between any two such side frame members is closed by three sealing bands, one on the indoor side of the gap and the other two on the outdoor side of the gap.
