The Vitrocsa V56 range offers infinite glazing surfaces using 56 mm thick double or triple glazing. This range represents an evolution of our current sliding windows. The Vitrocsa V56 window has been developed, keeping the same mechanical characteristics of the Vitrocsa systems which have proven their worth for nearly 30 years.

Key Features
Invisible Frame With One or Two Tracks
This configuration removes the architectural threshold between interior and exterior entirely. The frame is concealed beneath the finished floor, leaving only the glass visible. Double or triple glazing from 32 to 56 mm supports large sliding panels with surfaces of up to 20 m², creating a continuous visual and spatial connection.
Window Panels Pocket
The pocket solution allows one or more sliding panels to disappear completely into a dedicated wall cavity. When open, the glass leaves no visual presence, freeing the full width of the opening. This approach reinforces architectural purity while delivering a fully open façade without compromising the clean alignment of walls and finishes.
Open Angle
The open angle solution eliminates the corner jamb, allowing two sliding façades to meet without a vertical interruption. All rail configurations are possible, enabling full corner openings with uninterrupted views. This system enhances spatial flow and reinforces the sense of openness by removing structural visual barriers at the corner.
Mosquito Net
Several discreet solutions address insect protection without affecting the minimalist appearance of the system. An additional rail integrates a mosquito net directly into the sliding configuration, or a folding canvas is concealed within the vertical jamb. Coverage of up to 80 cm is achieved while preserving clean lines and ease of use.
