Formacore Curtain Wall Specifications
Formacore aluminum curtain wall panels meet the challenges of today's creative designers by using a unique composite design featuring an aluminum honeycomb core bonded to an aluminum face and liner. The result is a very flat and even panel with excellent peel strength and outstanding fire performance characteristics that weighs just 1 lb. per square foot. Available in a variety of panel edges, thicknesses and densities, it can interface anywhere in the curtain wall system as a spandrel panel, for soffits or fascia... in conjunction with glazing.
