ALT F50 Concealed facade vent

ALT F50 facade window system makes it possible to manufacture windows with outward opening of any type.

The variety of options for glass unit fixation allows to implement modern architectural projects with different requirements for energy efficiency of the systems.

This solution is a window integrated into the facade with a glass unit up to 38 mm thick fixation by means of a glued joint based on the textured silicone sealant.

The system allows to manufacture and install full-size inseparable from the main facade «floor-to-ceiling» systems with automatic or manual type of opening that ensure aesthetic appearance of the building. Facade windows are available in various hardware options from leading European brands.
