JI Roof 1000

The JI Roof 1000 Trapezoidal Insulated Roof Panel is used for pitched roofs or horizontal and vertical wall applications, and as an external insulated cladding panel for industrial, commercial and public buildings. Due to its rigid PIR core and metal inner and outer sheet, it combines thermal resistance with large spanning capability. The minimum roof pitch to be applied is 4° or more after deflection.

The reference product used for this study considers the product JI Roof 1000. This EPD is an average EPD for JI Roof 1000 produced in 3 different manufacturing sites in Belgium (Zwevezele), Germany (Ansbach) and France (Perpignan).

The reference product has a total steel weight of 8.171 kg and a foam thickness of 100mm. The steel weight is the weighted average of all configurations produced during reference year 2023 across the 3 different sites. Allocated according to production volumes in the year 2023, 67% from Zwevezele, 20% from Ansbach and 13% from Perpignan.

A methodology to estimate the environmental performances for other insulation thicknesses can be found in the Annex 1 and Annex 2.
