Dongbu Kangnam Tower's cladding utilizes a unitized curtain wall system with horizontal fins on the north and south facades. The east and west facades are simpler with clear glass and patterned spandrel panels repeated at each floor. Aluminum cladding transitions between the two groups of facades, helping to accentuate the sloping form of the building through the edges' solidity. Here, the exterior skin reinforces the building's form, a logical role for a system that often fights against - or tries to make up for the lack of - its form.
