The redevelopment works focused on restoring both the opaque and transparent elements of the building envelope. Particular attention was paid to the roof, which required refurbishment due to widespread rainwater infiltration. The use of the Isotec ventilated thermal insulation System made it possible to significantly enhance the roof’s energy performance, delivering a functional and stable build-up with excellent durability over time.
The extensive double-pitched roof, with a total surface area of 5,200 m² and showing clear signs of severe deterioration, was completely dismantled. Pantiles in good condition were carefully recovered and set aside for subsequent reinstallation. The deteriorated underlying slabs were then removed and disposed of, after which the supporting structure was cleaned and levelled. A waterproof and breathable Elytex-N membrane was laid on the substrate, followed by the installation of Isotec panels with a thickness of 120 mm and a pitch of 360 mm, selected to match the dimensions of the pantiles.
