This system allows for designing and building light mullion-transom curtain walls.

FA 50N system is classified as one of best curtain wall systems available on the market, considering thermal and acoustic insulation, water tightness and wind load resistance. The great variety of solutions possible within this system provides free shaping of the facade with regard to its geometry and colour scheme. This product has undergone tests in a European test institution.


• allows for creating constructions of various shapes and dimensions, in accordance with the architect's vision,
• complies with valid standards concerning water tightness, thermal insulation and fire resistance,
• wide variety of masking strips allows for diversified final appearance of the curtain walls,
• possibility of profile bending,
• possibility of creating many varieties with diversified parameters,
• possibility of using photovoltaic cells,
• possibility of combination with other Yawal systems.
