ALT IGF65 Internally glazed facade system

ALT IGF65 System provides wide opportunities for manufacturing of translucent balconies with thermal insulation. The distinctive feature of ALT IGF65 System is the possibility of assembly from inside of the room without scaffolding and lift platform.

On-site assembly can be carried out either in prefabricated sections or by separate structural elements.

The profiles of the ALT IGF65 System ensure visual lightness of the building due to the optimal configuration of profiles and the possibility to implement various joint solutions., as well as maintainability (replacement of glass units) during the process of facility exploitation.

The system offers solutions at different levels of thermal efficiency, allowing the use of various options for glass units.

Types of integrated units — ALT W 62 and ALT W 72 window and door systems.
