Under ANRU (the National Urban Renewal Agency), this renovation operation is complex as many different types of work are expected depending on the buildings. It fits within a more general framework that also encompasses redevelopment of green spaces and construction of new buildings. The project owner, OPALY, wanted to both preserve the overall consistency of the residence and develop the image of the neighborhood. The architects therefore wanted to create different architectural attitudes to give smaller quarters within the neighborhood, while keeping in mind simultaneous performance of renovation, new construction and green spaces.

The architects opted for an External Thermal Insulation (ITE) solution, which had the advantage, as well as compliance with the RT2012, of enabling work on an occupied site. From an architectural point of view, a mineral material was sought. After hesitating between a traditional concrete or Ductal® facing, the Ductal® option proved to be the most economical, particular from the point of view of implementation. The Ductal® cladding panels are 16 mm thick, and therefore weigh approximately 37 kg/m², ⅓ or even ¼ of the weight of traditional concrete panels.

Thanks to its large panel dimensions, the Ductal® cladding solution ensures compliance with the architect's layout drawing.

As Ductal® is not very porous, its aesthetic and mechanical durability is very high and the panels are easy to maintain and can simply be washed with water. The panels installed at street level are resistant to impact and are also treated with an anti-graffiti product.

Panels installed using concealed clamps on rails. The rails are fixed to a vertical frame, which is in turn fixed to a concrete support using brackets. All fastenings are made of aluminum.
