| Use advice for data set | Scope: This document is an association EPD for 1 m of PU Core sandwich panel with 100 mm thickness and it represents an average EPD, based on vertical averaging of the specific producer datasets under consideration of the yearly productionamounts. 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 member companies of the European Association for Panels and Profiles have provided data for the year 2022: 1. ArcelorMittal Group, Construction Division ArcelorMittal Construction Austria ArcelorMittal Construction Belgium ArcelorMittal Construction Deutschland ArcelorMittal Construccin Espaa ArcelorMittal Construction France Arcelormittal Construction Polska ArcelorMittal Construo Portugal Europerfil Pflaum & Shne Bausysteme2. Assan Panel Sanayi ve Ticaret 3. Brucha 4. Fischer Profil 5. Huurre Iberica 6. ISOCAB France (Kingspan Group) 7. Isolpack 8. Joris Ide Belgium (Joris Ide Group) 9. Metecno Bausysteme 10. Montana Bausysteme 11. PAGOUNI 12. SAB-profiel These companies are representative for the European production of steel faced sandwich panels with polyurethane core. This EPD comprises an annex with LCA results for two additional sandwich panel thicknesses: 40 mm and 160 mm. Additionally, the EPD annex contains LCA results for 1 kg steel sheet used for the panel faces and 1 m polyurethane (PU) used for the panel core, which allows the combination and estimation of LCA results for different panel variations. System boundary: Type of the EPD: cradle to gate - with options, module C1-C4 and module D (A1-A3, C, D and additional modules A4 and A5). 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. Module A4: Delivery to the construction site with a transport distance of 100 km. Module A5: Disposal of transport packaging at the construction site and energy for installation. Module C1: Dismantling with the use of machinery (diesel driven). Module C2: Transport to the site of end-of-life treatment- transport distance of 50 km. Module C3: Metal recycling of the steel sheets and incineration of the PU core material with energy recovery. Module D: Potential benefits for substitution processes or recycling materials from modules A5 and C3. For the end of life, it is assumed that the steel proportion is recycled with benefits for the recycling potential declared in module D and the PU proportion is incinerated (module C3) with benefits given for energy substitution in module D. | ||
| Technical purpose of product or process | The products are used for self-supporting and structural 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 is made of polyurethane rigid foam according to /EN 13165/ with sealing tapes. The core is bonded to the steel sheets on both sides, to ensure a certain resistance to shear forces of the panel. 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 1 m of sandwich panel. The averaging is done based on the yearly production volume per company. | ||
