This elevation detail shows the intersection of an aluminum curtain wall mullion and a horizontal stack joint. The assembly features an aluminum fin centered on the vertical mullion axis, with four-sided structural silicone glazed joints defining the glass lite transitions. Precise dimensional callouts locate the edges of the structural silicone joints, the stack joint offset, and the mullion components beyond. The stack joint includes a typical one and three-quarter inch vertical dimension spacing centered on the horizontal joint centerline.
