Kawneer upgraded its window wall portfolio with the launch of the MetroView 4-SSG Window Wall. The unitized system was developed to meet a growing trend toward larger, uninterrupted spans of glass. MetroView 4-SSG delivers visual impact to both new construction and retrofit slab-to-slab commercial applications. The system is suited to mid- to high-rise multifamily, office and institutional projects that need a combination of daylighting, enhanced acoustic capability and thermal efficiency.
