Non-insulated, highly flexible sliding and lift-and-slide system with narrow face widths for large-area glazing units

For indoor areas or regions in which no additional thermal insulation is required, the Schüco ASS 50.NI sliding and lift-and-slide system offers optimal solutions with high transparency. With narrow profile face widths, the non-insulated aluminium construction enables large glass areas with maximum light penetration, whilst requiring a minimum amount of space and generating almost no noise when the sliding units move. Together with a multitude of fittings and handle combinations, and a diverse range of opening types, Schüco ASS 50.NI opens up a wide design spectrum for architects and developers.

Optimised fabrication steps guarantee simple production and efficient installation. Numerous system components round out the system portfolio.
