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.

  Minimal Frames have been outstanding throughout the process, from planning to install and aftercare. At all times their communication has been top-notch; fast and effective. Quality of the glazing itself is excellent, the installation process was pain free and the windows and pivot door look incredible. They’ve been really strong on aftercare too, checking in that all works well and correcting a very minor issue quickly. I really cannot fault any part of our experience and wouldn’t hesitate to use them again and recommend to others.

  Bob and his team have taken on our tricky glass extension installation, embraced its complexity and delivered it to perfection. It truly is a stunning addition to the house. The team that worked on site was extremely pleasant; always on time, quiet and polite. The project turned out to be long for its complexity, but the final result was worth the wait. We are very pleased with the outcome and hope it will keep us cool even in the heat of summer. Thank you MFP team! With kind regards, Emil and Narmina

  Bob and Minimal Frame have stepped in to help sort out problems with another glazing company. He has kept us well informed throughout and has worked tirelessly to deal with the manunufacturers to get the doors delivered and the install started. We were 90% done by Christmas which was a huge relief. I've found Bob to be straightforward, transparent and responsive and am very grateful for his help fixing our previous issues. Additionally, his install team have been highly professional and meticulous in getting the install right.
