Invisible aesthetics. Unrivalled insulation.
The TH+ Invisible Frame System is designed for high-performance architecture where transparency, thermal comfort, and design freedom converge. It offers powerful insulation, weather resistance, and security in a system that virtually disappears.
Thanks to its advanced thermal break, this system is ideal for exposed, high-altitude or coastal settings. All framing is hidden from view — enabling seamless floor-to-ceiling glass with minimal sightlines and no architectural intrusion.
Whether you’re building a luxury home, gallery space, or contemporary facade, the TH+ delivers the balance of performance and purity architects demand. It’s built to handle scale, climate, and elegance — effortlessly.
The TH+ uses recessed aluminium profiles and integrated sliding tracks to conceal the entire frame within the floor, ceiling, and wall structure. Only the vertical glass connection remains visible — a slim 22 mm detail that keeps your focus on the view.
Even with oversized glass panels, the system glides effortlessly thanks to hidden stainless steel rollers. Optional add-ons like motorisation, insect screens, and open corners allow it to adapt perfectly to your space and lifestyle.
