FA 50N SL System

FA 50N SL is used to create modern curtain walls of simple and complex shapes.

Its purpose is creating structures with flat external surface (no aluminium profiles visible). It combines the advantages of classic transom-and-mullion facade (quick assembly) with the aesthetic appearance of structural facade.
