The absence of thermal insulation and high humidity level in all ground floors with consequent disruption of the bricks due to the effect of salt: this was the main problem of the structure of Pagnana House, an historical building of great interest located in Gorgonzola, near Milan.

Dehumidification and energy upgrading were the most important objectives of the project, that affected the whole wall and that made necessary the application of integrated Diasen dehumidifying system. The criticality of the situation and the simultaneous desire to provide immediately a sufficient thermal resistance excluded out the use of natural or mineral-fibers panels, subjected to dampness absorption, even if transpirant. At the same time it has been rejected the idea of using panels made ​​of polystyrene or polyurethane, that does not suffer degeneration in contact with humidity but do not have sufficient levels of breathability, and therefore would not have fulfilled the essential function of dehumidification. Thus it was applied Diasen thermal and dehumidifying system.

After complete removal of existing plaster, damaged because of the rising dampness, we proceeded with the application of WATstop anti-salt osmotic barrier applied by brush directly on the exposed wall, for a total height of about 2 meters. After WATstop application, next step was the application of Diathonite Evolution plaster, for a total thickness of 5-6 cm. This application has involved all the external perimetral walls of the structure. Then we proceeded leveling Diathonite through the use of the finishing smoother Argacem HP.
