About the TH+ Curved System

Architectural movement with structural integrity

Vitrocsa’s TH+ Curved System is the answer to architects seeking elegance without compromise. It allows curved glass panels to slide smoothly along precision-engineered tracks while maintaining the brand’s signature minimalism and performance credentials.

With its saline-treated aluminium frame and high-quality track system, the TH+ curved model is engineered for both coastal and high-wind zones. It allows for large glazed sections to follow the arc of your space, creating a dynamic visual flow with outstanding performance.

This system is ideal for panoramic façades, curved terraces, atriums, and statement entrances. Whether manual or motorised, the TH+ curved slider adapts to your space while providing premium insulation and security.

How the Curved System Works

Using precision-formed curved glass and tracks, the panels follow a defined radius along custom-configured paths. With a minimum sliding radius of 3 metres and fixed panes down to 1.5 metres, the system is highly adaptable for design-led applications.

Thanks to embedded frames, stainless steel rollers, and optional automation, the movement remains smooth and silent. Glazing overlaps are minimal, and panels can be secured with locking points or integrated sensors — all without visible hardware.

  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.
