Completed in 2015, the Skyway Monte Bianco in Courmayeur – Entrèves, Italy, represents a remarkable achievement in high-altitude architecture and façade engineering. Connecting three stations positioned at 1,300 metres, 2,200 metres (Pavillon du Mont Fréty), and 3,466 metres (Punta Helbronner), the cable car offers visitors an uninterrupted panoramic experience overlooking the Aosta Valley and the Mont Blanc massif.

Designed by Studio Progetti Cillara Rossi, the project required a façade solution capable of blending seamlessly with the surrounding alpine environment. The architectural concept called for perfectly neutral glazing with excellent thermal insulation, high structural performance, and maximum visual clarity, essential qualities at extreme altitude where temperature fluctuations, wind loads, and snow exposure are significant.

To meet these requirements, the façades and curtain walls were specified with Planibel Clearvision, AGC’s low-iron extra-clear glass. Thanks to its high light transmission and superior colour rendering, the glass eliminates the typical green tint of standard float glass, ensuring pure transparency and allowing visitors to fully appreciate the 360-degree views.

The glazing package incorporated Planibel Extra Clear Clearvision, combined with Stratobel laminated safety glass and Stratophone acoustic laminated glass. In total, nearly 2,000 square metres of glass were cut to size, with each unit manufactured in a different dimension. The elements were assembled as triple-glazed units by AGC Interpane in Plattling to guarantee optimal thermal performance.

Logistics posed an additional challenge. Due to the hostile terrain and unpredictable weather conditions, the glass panes were transported to the summit using a pulley system during limited installation windows between May and October.

The completed façade delivers exceptional clarity, safety, and energy performance, transforming the stations into transparent observatories suspended above the Alps. The Skyway Monte Bianco stands as a benchmark project demonstrating how advanced glazing technology enables architecture to coexist harmoniously with extreme natural landscapes.
