Kawneer Co. Inc., an Alcoa business, has introduced the 1620/1620 SSG (structuralsilicone glazed) curtainwall system. With a 2-inch profile, the curtainwall is suited for use in low- to mid-rise commercial applications. It provides slim sightlines that allow more light to enter a building. The system is engineered with a thermal break and can accommodate double-pane insulating glass. A fiberglass pressure plate option provides additional thermal performance.
