Kawneer introduces the new 1620UT/1620UT SSG Curtain Wall System. Built on the success of the 1600UT Curtain Wall platform and a narrow 2-inch (50.8 mm) sightline, the systems feature an engineered polymer thermal separator and accommodate 1-inch insulating glass, making them ideal in climates where high thermal performing façades are needed. Offer several design options including a traditional captured look or a two-sided vertical SSG mullion solution that permits greater uninterrupted sightlines.
