A four-sided structural silicone glazing stack joint connection within an aluminum curtain wall system. The assembly features an aluminum fin centered on the mullion centerline with specified dimensional clearances and stack joint reveals. Precise measurements and centerline references govern the alignment of the mullion beyond the joint edge. The construction coordinates the vertical mullion layout with the horizontal stack joint to maintain weatherproofing and thermal integrity.
