JI Onduroof 1000 is an insulated roof panel suitable for pitched roofs. The sandwich panel consists of an outer sheet with a corrugated profile, a polyisocyanurate (PIR) foam core without harmful CFC-HCFC compounds, and a lightly ribbed inner sheet. The outer sheet has the aesthetic advantages of a traditional corrugated sheet and is therefore an ideal solution for renovation and new construction projects in both the industrial and agricultural sectors.
