About the V56 Invisible Frame System

Engineered to disappear, designed to impress

The Vitrocsa V56 Invisible Frame System delivers the purest architectural expression of openness. It combines a robust structural profile with advanced insulation and a design where all visible framing vanishes into the surrounding structure.

With 56 mm glazing and no visible tracks or threshold interruptions, the system performs under extreme conditions while maintaining a sleek aesthetic. Each installation is tailored with track options and accessories to match your unique space and performance needs.

From luxury homes to commercial facades, the system’s flexibility and performance ensure it adapts to any design vision — allowing uninterrupted light and movement across even the most complex architectural geometries.

How the Invisible Frame System Works

Using embedded aluminium profiles and recessed track configurations, the system hides structural components inside floors, ceilings, and walls. This leaves only the glass in view, with a slim 22 mm vertical sightline where panels meet.

Despite supporting extremely large panels, the sliding system operates smoothly thanks to concealed stainless steel rails. Advanced sealing ensures weather protection, while motorisation and screen options offer enhanced usability and comfort.
