Since reinforced concrete and structural steel entered the picture, engineers have learned that thinner columns could still support a building. Even more interesting, they could exist independent of the exterior, meaning outer walls no longer had to shoulder structural loads. Today these outer “curtain” walls offer amazing aesthetics, but they still also serve an important role in sustainability and protecting a building envelope.
