The explosion of new cladding materials could be traced to a number of causes: a trickling down of technology from other industries, the effort to do more with less, and the simple urge to innovate. As more products enter the marketplace, there's also a counterpoint, where traditional cladding materials are being manipulated and adapted for very specific needs. Join Blaine Brownell of the University of Minnesota, Martin Augustyniak of Walter P. Moore, Alissa Schmidt of Viracon, Will Babbington of Studio NYL, and Matt Kreilich of Snow Kreilich Architects as they look at a broad range of material developments, from glass that inverts the modernist notion of immateriality, to developments in high-performance membranes, to extraordinary uses of ordinary materials.
