ALT F50SG Structural glazed curtain wall

ALT F50SG system allows to create all-glass façades of any configuration. Maximum transparency and visual lightness are due to the optimal configuration of profiles and possibility to implement various joint solutions.

Types of integrated units:

  • ALT window and door systems;
  • integrated facade windows with different opening types;
  • smoke hatches.
