The temporary communication panels were replaced by a permanent solution using CONIPHER fixations, in particular those used for the installation of photovoltaic modules. This new use of the fixations (the fourth after photovoltaic modules, the glass canopy and the VMC extraction) shows the versatility, flexibility and modularity provided by the CONIPHER system. The installation was supervised by the Crayon Bleu agency, and carried out by the printing company AGG Print.
