Irregularly sized zinc-colored metal panels provide an interesting visual feature on the new Cedar Rapids Public Library. Comprising aluminum composite material (ACM) panels with a zinc patina finish, the panels juxtapose with smooth-surface materials to bring a complexity and depth to the Iowa building’s façade.

Curtain walls are often the focal point of aesthetic design for a multi-story building. Behind the attractive façade are the pedestrian, yet arguably more important, functional components that ensure safety and reliability—fasteners that transfer loads both imposed and experienced by the assembly to the building’s structural framework.
