In a joint assembly of two adjacent curtain wall units, an exterior gasket is divided into a pair of interfitting male and female halves carried by respective exterior parts of the adjacent vertical frame members. An interior gasket mounted between opposed interior parts of the adjacent vertical frame members has opposite edge portions each fitted in a recess of the respective interior part and projecting beyond the interfitting edges of the male and female gasket halves. In installation, one of the opposite edge portions of the interior gasket can be observed by the workman's eye through a gap between the male and female gasket halves while it is being inserted into the recess of the corresponding interior part.
