ALT F50 Curtain wall system

ALT F50 Classic facade

ALT F50 curtain wall system is designed to make projects of different engineering complexity: curtain walling, roofs, skylights, winter gardens and other design solutions.

The system provides maximum transparency and visual lightness due to the optimal configuration of profiles and possibility to implement various joint solutions.

System description



Transom profile
  • T–cleat fixation elements have been removed – section optimization
  • The channels in the sealing installation area have been removed – enlarged transom front line for better bearing capacity
  • Enlarged transom side line up to 2,5 mm – more effective aluminium allocation throughout the section for higher transom rigidity towards the weight of the glazing unit
  • Added grooves for the spring cleat installation – easier facade fabrication
Water deflection plug for faceted facades
  • This solution is applied to the internal side of faceted areas allowing the water go from the transom to the mullion
  • Universal element for any turning angle is cut according to the suitable notch
Adjustable support kit
  • Provides the possibility of facade mounting from a floor slab
  • Increases installation speed by reducing the quantity of operations onsite
  • Universal kit for all mullion sizes
  • Wide adjustment diapason
Acoustic dampening inserts
  • Provide sound insulation between the adjacent premises
  • Guarantee thermal insulation while installation of the brackets for suspended decorative and shading elements
  • Remove the gap between the mullion and reinforcement profile
Spring cleat for transom fixation
  • Simple and high-performance installation of transom sections
  • Universal fixation for all transom sizes
  • Easy dismounting of the transom without losing functionality of the unit
  • Possibility for glue injection for additional cleat fixation
  • Drilling of one hole instead of 4 for standard cleat
Foamed transom spacer insert
  • Aesthetic connection between mullion and transom
  • Easy installation and absence of damage after fabrication onsite
  • Minimal visual appearance in comparison with a plastic cap
  • Can be cut in case of using on the faceted facades
Drainage spout
  • Installation on the mullion
  • Special grooves for sealant application and fixation by the screw
  • Secure fixation and tightness
  • The notches for various glazing thicknesses
Moisture transfer plug
  • Special holes for fixation by the self-tapping screw and secure sealing
  • Possibility to install after the mullion assemblage
  • Solid continuous gasket line
  • Technological ‘legs’ prevent the sealant from getting into the mullion chamber
  • Double sealing guarantees the secure water deflection
