Particular attention was given to the roof, whose refurbishment had become necessary 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, creating a functional and stable build-up with excellent long-term durability.
The extensive double-pitched roof, with a total surface area of 5,200 sqm and showing clear signs of severe deterioration, was completely dismantled. Roof tiles in good condition were carefully salvaged and set aside for subsequent reinstallation. The waterproof and breathable Elytex-N membrane was laid over the substrate, followed by 120 mm Isotec panels spaced at a 360 mm pitch to match the sizing of the roof tiles. The project successfully combined energy efficiency, durability, and historic preservation, providing the Department of Economics with an updated, high-performance roof that fully integrates into its architectural context.
