Method and system for improved curtain wall sealing

摘要

In one aspect, the present invention relates to a plug of the type utilized for sealing a junction between a horizontal member and a vertical mullion of a curtain wall. The plug may include a plug body. The plug body may include a front body portion, a rear body portion, a left body portion, a right body portion, a top surface disposed between the left body portion, the right body portion, the front body portion, and the rear body portion. A rabbet is disposed across the front body portion. A spacer flange extends from the front body portion. A plurality of chamfers are disposed between the top surface and the left body portion, the right body portion, and the rear body portions. The plug is sized to occupy a gap formed in the junction between the horizontal member and the vertical mullion of the curtain wall. The rabbet and the plurality of chamfers form a plurality of large crevices between the plug, the horizontal member, and the vertical mullion. The large crevices allow penetration of a sealant therein.
