FA 50N INV is a modern system intended for making windows embedded in the supporting grid of the FA 50N and FA 50N SL mullion-and-transom curtain wall.
It allows for construction of windows that open inwards of the curtain wall with a tilt-and-turn, turn-and-tile, turn or tilt function.
A characteristic feature of the system is the solution that makes the frame and window sash invisible outside the curtain wall. The profiles of the curtain wall columns are shaped in such a way that they also function as a window frame.
