Since 2015, all buildings are being renovated to offer new thermal, functional and architectural standards designed by the architects Palloix et Rosset, project manager.

Tissot, company specialized in cladding and tightness work and in charge of the roofing, water tightness and skylights work package has been in charge of renovating full sections of the roof, including the removal of existing vaults and installation of a dry – isolated and waterproofed – roof.
The new skylights are all equipped with a 20mm alveolar polycarbonate infills and 7 Pearl technology partitions which was chosen by the architects to enhance the living rooms with an aesthetic performance thanks to the microbeads sparkling effect but also to improve the Bluesteel RPT acoustic performance. All skylights are with thermal broken profiles and equipped with a sunshade screen.
The Screen-Dome, here longitudinal, dissociated from the building’s window partitions on the exterior gives the building a nice design but also removes the direct sunrays effects while protecting from the sun during the summer and letting in the natural heat in winter. One NSHEV with PCA Pearl Inside infill and Screen-Dome solar factor is 0,12.
Currently, there are 79 Bluesteel RPT Fix skylights, with 70 of special dimensions 820 X 2900 mm, 25 Bluesteel RPT Pneu NSHEV of dimensions from 1100 X 1100 mm to 1500 X 1500 mm, 18 Bluevoûte RPT Fix with 14 of special dimensions 2600 X 32000 mm and 1 Bluesteel Pass for roof access.
