Making the Greatest Views in Paris Possible with High-Performance Glass

by Guest Blogger

Paris’ Eiffel Tower sits high on the list of the world’s most recognizable landmarks. Built in 1887, the historic tower has undergone numerous renovations over the years, with one of the most recent taking place in 2014, including construction of the breathtaking Gustave Eiffel reception room and the Ferrié Pavilion on the tower’s first floor.

Wowing visitors since its opening, both projects incorporated spectacular glass designs, made possible with cutting-edge design technology and the inherent flexibility and performance of Super Spacer® technology from Quanex.

New Frontiers in Design. In recent years, digitization has transformed architecture. Buildings and façades are today being realized that wouldn’t have been possible without modern 3D design and computer-aided algorithms.

By virtue of its inherent flexibility and versatility, Super Spacer technology has helped make possible some of the most forward-thinking, free-form glass façades of the past decade. The spacer technology conceals itself in the overall structure of a glass façade and has therefore become indispensable to the aesthetics of many cutting-edge designs around the globe.

Such was the case in the Eiffel Tower renovations. A key requirement of the renovated viewing platforms was to make the platform itself more attractive, made possible with a unique glass design from the Parisian architecture firm Moatti-Rivière.

As a result, the new pavilion is complete with a museum and an information and service area, each reconstructed between two pillars. In the case of the already-existing 58 Tour Eiffel restaurant, the glass façade was brought in line with those present in the other two pavilions: glass surfaces facing inside and outside, a 1,400-square-foot glass floor which opens up a view of the Champ-de-Mars below and an 8-foot-high surrounding glass balustrade. The dramatic resulting view delights visitors with transparency in every direction, enabled by double-kinked glass façades that follow the angle of inclination of the pillars.

Uncompromising performance. In order to meet the energy requirements, façade builder HEFI opted for insulating glass elements made of bent quality glass from the Italian glass bending specialist SUNGLASS Industry srl using Super Spacer® TriSeal™ Premium Plus, offering the needed thermal performance for the project.

In order to ensure that the façades withstand the wind conditions on the Eiffel Tower, the impacts of different climate loads on the edge seal and the panes were simulated using the finite element method, and the fit of the panes was inspected using a 3D scanner following installation.

Made possible in part by the flexibility and performance of Super Spacer, Eiffel Tower visitors from around the world have enjoyed the renovated pavilion for five years, and will continue to do so for the foreseeable future.
