Orgues de Flandre is a social housing building complex located in the 19th district of Paris. In the context of Paris' climate protection plan*, the architect firm Atelier Lion Associés is renovating the façade of 2 towers of the complex. Littoral® and ST 300 Kristal®** Hairclyn steel sheets provided by ArcelorMittal Construction, give the buildings a fresh look to embody modernity.
An organ at the heart of Paris
Designed by architect Martin Van Treeck, Orgues de Flandre, built in the 1970s, is composed of 6 buildings (4 towers and 2 linear buildings) offering in total 1,950 flats. This building complex is an important landmark in Paris’ skyline and in the history of modern Parisian architecture and it is classified as an architectural heritage building of the 20th century.
Measuring between 25 and 38 floors, the towers of Orgues de Flandre are highly recognisable from afar. Due to their barrel shape, each with a different size, they are reminiscent of an organ, hence the name Orgues de Flandre (Organs of Flanders).
Preserving the architectural homogeneity
Social landlord I3F, who owns 2 of the 4 towers, started an ambitious energy rehabilitation and renovation programme. Supported by Atelier Lion Associés, the aim of the project was to preserve the architectural homogeneity of the complex, thus choosing steel sheets, durable and wind resistant. To meet the architects’ requirements and provide thermal insulation to the buildings, Jean-Michel Boulestin, prescriber on this project, opted for a solution developed in collaboration with ArcelorMittal Construction France and using Littoral® relief steel sheets and ST 300 profiles coated with Kristal®**Hairclyn.
To ensure a perfect alignment and integration of the windows, a special profile was developed for this particular project with:
Accessories such as splitting flaps, window flaps, joint covers around the windows and curved angles have been designed to align with the façade plan.
* Paris' climate protection plan aims to a reduction of greenhouse gases of 75% by 2050 compared to 2004. A 25% objective is foreseen for 2020.
** Kristal® = Based on Aluzinc®, a metallic coated steel produced by ArcelorMittal Europe – Flat Products in Dudelange (Luxembourg)
From the 1970s to 2016: Orgues de Flandre leaps into the future
Kristal® is an ideal material, combining design, aesthetics and durability. It fulfills perfectly the requirements of the architects: the solidity of steel, the protection of zinc and the inalterability of aluminium. Kristal® gives the towers of Orgues de Flandre an exceptional light-reflecting finish – specifically tailored for modern and contemporary façades – which will retain its shine for a long time, thanks to its excellent resistance to atmospheric oxidation.
Thanks to its natural silvery spangle, Kristal® is the creative touch to transform a unique building into a remarkable one.
