Insulated metal under-tile system

Insulated system for roof tiles

The Insulated Sottocoppo is the natural evolution of the original sheet: by integrating a layer of expanded polyurethane insulation into a continuous production process, it provides new features such as reduced condensation, increased walkability, improved load resistance, and enhanced thermal performance.
The Insulated Sottocoppo is automatically supplied with the terminal part of the sheet without the insulating layer, creating an “anti-drip” effect and ensuring perfect overlapping in the case of long roof slopes.

The content of this calculation table is to be considered approximate and for indicative purposes only. It is the responsibility of the designer and/or user to carry out the relevant structural calculations for each specific application and to define the applicable design specifications of the roofing system.

Thanks to the possibility of installing full-length sheets, installation time is significantly reduced and complete waterproofing of the roofing system is ensured.
