Stick system curtain wall 4F1

metal and glass

Extensive glass surfaces need greater inertia and consequently mullions with larger sections: 4F1 proposes the solution with structural mullions in steel, stainless steel or corten steel of reduced sections (50 mm) and elevated moment of inertia to guarantee the static values required while maintaining the effects of lightness and transparency of the faҫade. 4F1 interprets the design of the frame in numerous possible variations and integrates windows and doors guaranteeing the very best performance. The 4F1 system performance has been tested by the best European certification laboratories in conformity with the standard EN 13830 regulations.
