FA 50N EI SL system

The FA 50N EI SL system curtain wall is a semi-structural façade based on the FA 50N EI system.

The system allows the aesthetics known from the FA 50N SL version to be retained, so that the FA 50N EI SL fire-resistant façade does not visually differ from the non-refractory version of the system.

Advantages of the system

  • possibility of maintaining the aesthetics of the façade without any
    visible deviation from FA 50N SL system without fire resistance,
  • the system allows the construction of suspended or filling walls with fire
    resistance class EI 60,
  • the system allows the construction of both flat and broken walls,
  • possibility of installing fire protection doors in the façade.
