A window with a hidden hinge is one of the most sought-after solutions in modern architecture. The main goal of the system is to minimize visible profiles and maximize the glass surface. Unlike standard windows, in this type of system the opening sash is completely hidden in the main frame.

Advantages
Maximum natural light: Since the visible part of the profile is minimized, the glass area increases, which allows much more natural light to enter the interior.
Ideal symmetry of the facade: The exterior maintains a unified look. From the outside of the building, the opening and fixed stained glass windows look identical.
Aesthetics: Ideal for modern, minimalist style homes and commercial spaces, where design is a top priority.
