1620UT / 1620UT SSG Curtain Wall Systems
Kawneer’s 1620UT Series merges a minimalistic 2″ sightline with high-performance thermal and seismic capabilities, making it an ideal solution for low- to mid-rise curtain wall applications. With support for both double- and triple-pane glass, vertical SSG, and various mullion options, this system offers flexible detailing and long-lasting performance in challenging climates.

Concealed fasteners, engineered polymer thermal breaks, and integrated entrance compatibility contribute to a smooth monolithic aesthetic while achieving high ratings in structural, thermal, and acoustical testing.
