ABSTRACT OF THE DISLOSURE A sealing system for a curtain wall construction has a packing block of soft elastomeric material mounted at the cross joint between four adjacent curtain wall units. At their one ends, first and second horizontal gaskets, each mounted between the upper and lower curtain wall units, are disposed against opposite sides of the packing block. First interior and exterior vertical gaskets are mounted between the two upper curtain wall units to define a first vertical space. The lower end of the first interior vertical gasket is disposed against the top of the packing block, while the lower end of the first exterior vertical gasket is spaced from the top of the packing block to define therebetween a drainage passage through which the vertical space opens to the exterior. Second interior and exterior vertical gaskets are mounted between the two lower curtain wall units to define a second vertical space. The upper ends of the second interior and exterior vertical gaskets are disposed against the bottom of the packing block.
