| Use advice for data set | Scope: This document is an association EPD and it represents an average EPD. Its applicability is limited to continuously produced double skin steel faced sandwich panels with an insulating core made of polyurethane, which are manufactured by member companies of the European Association for Panels and Profiles. The following sixteen member companies of the European Association for Panels and Profiles have provided data for the year 2016: 1. ArcelorMittal Construction Deutschland 2. Falk Bouwsystemen 3. Fischer Profil 4. Hoesch Bausysteme 5. Huurre Iberica 6. ISOCAB France 7. Isolpack 8. ISOPAN Deutschland 9. Italpannelli 10. Metecno Bausysteme 11. Montana Bausysteme 12. N.V. Joris Ide Belgium 13. Romakowski 14. SAB-profiel 15. Salzgitter Bauelemente 16. Trimo. These companies are representative for the European production of sandwich panels with polyurethane core. System boundary: Type of the EPD: cradle to gate - with options Production stage (modules A1-A3) includes processes that provide materials and energy input for the system, manufacturing and transport processes up to the factory gate, as well as waste processing. For the end of life it is assumed that the steel proportion is recycled with credit for the recycling potential declared in module D and the PU proportion is incinerated (module C3) with credit given for energy substitution in module D. | ||
| Technical purpose of product or process | The products are used for structural, self-supporting and non-supporting applications in roof, wall and ceiling structures. Sandwich panels in wall and roof applications take on tasks of the building physics, especially sound, heat and moisture safety. They simultaneously perform the function of air tightness of the building envelope. | ||

| General comment on data set | The EPD applies to prefabricated double skin steel faced sandwich panels with a core made of polyurethane, which are produced by member companies of PPA-Europe. The profiled internal and external faces are made of a core of steel, which is protected against corrosion with zinc and organic coatings. The thermal insulating core material is made of polyurethane according to /EN 13165/ with sealing tapes. The core is bonded on both sides with resistance to shear forces to the profiled steel sheets. The LCA is based on vertical averaging of the specific producer datasets under consideration of the respective yearly production amounts. | ||

| Technology description including background system | Double skin steel faced sandwich panels with a core made of polyurethane (PU) are prefabricated elements used for structural, self-supporting and non-supporting applications in roof, wall and ceiling structures. Sandwich panels in wall and roof applications take on tasks of the building physics, especially sound, heat and moisture safety. They simultaneously perform the function of air tightness of the building envelope. The PU cored sandwich panels are manufactured on a continuous production line. The line speed varies depending on the thickness of the panel. The faces of the panel consist of steel sheets with zinc and organic coatings for protection against corrosion. The production process begins by unwinding the steel coils and continues with the roll forming of the sheets. At the foaming station, PU liquid foam is spread on the bottom sheet on the line. Once it goes out through the nozzles, the foam starts slowly to expand and binds with the top sheet. The sheets together with the PU foam are pulled in the double belt press, where the PU foam becomes rigid and the bond gets stabilized at the wished panel thickness. Afterwards, the panels are cut at the wished length, stacked and packaged. Technical data: Technical specifications for sandwich panels with a core made of polyurethane are: /EN 14509/ /EN 13165/ Declared unit: The declared unit is 1m² of sandwich panel. The averaging is done based on the production volume per company. | ||
