Perforated Ductal® roof bathes travellers in Mediterranean sunshine in new Montpellier TGV high-speed train station

18 December 2017

The southern French city of Montpellier enjoys an average of 2,618 hours of sunshine each year. Now, thanks to the perforated Ductal®  roof on the new high-speed (TGV) train station, the sun will be there to welcome travellers as they benefit from greatly reduced travel times between other major French cities and Spain.


A natural twist on high speed travel

The first TGVs will leave from Montpellier station in mid-2018, carrying passengers to Paris, Lyon and Barcelona, from platforms landscaped to reflect the natural inspiration of the entire project. Designed within the Projet Oz: Nature Urbaine (urban nature) project, which aims to fill a 350-hectare urban area with green space as well as housing, offices and transport links, the station design incorporates nature-inspired elements both inside and out; from the platforms to the garden parvis.

Architect Marc Mimram has also drawn inspiration from the mediterranean surroundings in the inclusion of a perforated Ductal UHPC roof, which will filter direct southern light into the station. The roof is made of 100 precast modular Ductal® palms. Each unit is just five centimeters thick, but over 20 meters in span, made possible by the strength and durability of Ductal® UHPC even in very thin panels. They are perforated in a random pattern, following the passage of the sun throughout the day. Whatever time it is, a Ductal® roof ensures it’s always sunny in Montpellier!
