| Use advice for data set | Scope: This declaration is an association EPD that represents an average product of the WPC manufacturing VHI member companies. The average is the weighted average of the manufacturer's data. The proportion of the production volume covered by the LCA is 84 % of the total production volume manufactured by all association members in the reference year 2021. System boundary: Type of EPD: cradle-to-gate, with options In accordance with EN 15804 the following modules are used: Module A1-3 The aggregated representation in the form of A1-3 is used for production. This includes the supply of raw materials, the production of the WPC façade elements, all transportation to the manufacturer, the required energy consumption and resources, as well as all production waste that may accrue. Module A4 Transportation of the product from the manufacturer to the construction site Module B2 Maintenance of the WPC façade elements during the utilisation phase: cleaning of the WPC façade elements Module C2 Transportation of the scrapped product to the recycling yard or to the manufacturer Module C3 Waste treatment, such as thermal or material utilisation: On account of the selected system boundaries (definition of the end-of-waste status), no disposal (Module C4) of the WPC façade elements takes place. This means that only the export of the properties inherent in the material is included in the balance. Module D Credits and debits outside the system under review, through thermal and material utilisation | ||
| Technical purpose of product or process | WPC cladding profiles are for cladding façades and can only be used as a non-load-bearing structural element (no construction engineering approval). The products pose no risk to health and are technically safe. | ||

| General comment on data set | The declared product is a wood-polymer cladding profile specially suitable for outdoor use. The plastics matrix can consist either of polyethylene (PE), polypropylene (PP) or polyvinylchloride (PVC). This EPD does not refer to a specific product of one manufacturer, but declares the average environmental quality for all WPC cladding profiles produced by member companies of the VHI. The information represents 100 % of the German market. Detailed data can be obtained from the product description of the manufacturer in question. | ||

| Technology description including background system | The following figure shows an example of the process of extruding WPC elements: There are two different processes in the production of WPC facade elements. One is direct extrusion, in which the raw materials are added directly, and the other is a two-stage process of compounding and extrusion. In this, the raw materials are first processed into compounds and then fed into the extrusion process. Both methods are used in practice. After cooling, the WPC facade elements are cut to size and packed for transport. The WPC facade elements are produced in Germany and neighboring countries. The façade elements leave the extruder system with a moisture content of 0%. This is followed by moisture absorption from the environment and thus swelling processes and minor dimensional changes. All manufacturers involved have implemented a quality management system based on or according to /ISO 9001/. Technical data: The technical construction data listed in the following apply to all WPC cladding profiles made by the manufacturers involved. Declared unit: The declared unit is defined as follows: 1 m² of installed WPC cladding profiles, with the dimensions 1,000 - 4,000 mm/80 - 240 mm/18 - 25 mm and a surface weight of 7.79 kg/m², over a service life of 40 years. The composition of the WPC cladding profiles results from the weighted average, depending on the production volume of the manufacturers involved. | ||
