About the V32 Invisible Frame System

Slim-profile architecture with serious performance

The V32 is Vitrocsa’s single-track solution for thermal performance in minimalist form. Its 23 mm vertical connection ensures elegant lines while fibreglass towers embedded in the frame add structural and insulation advantages.

The system is built to meet the demands of extreme environments — including high winds, saline air, and solar exposure — thanks to corrosion-resistant treatments and robust jointing. All mechanical components are engineered for longevity and smooth operation.

Like all Vitrocsa invisible frame systems, the V32 is customisable with open corners, motorised opening, and fully pocketed panels. It offers the same architectural freedom Vitrocsa is known for — with the added benefit of thermal performance tailored to more demanding locations.

How the Single-Track Invisible Frame Works

The V32 uses a single sliding rail embedded into the floor, ceiling, and side walls. This keeps the track and frame completely hidden, while glass panels glide on concealed rollers. The 23 mm connection between panes is nearly imperceptible.

Its thermally broken profile, fibreglass reinforcement, and resistance to corrosion make it an optimal choice for projects requiring both high performance and a clean, modern aesthetic. The system can also accommodate accessories such as insect screens and motorised control.

  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.
