| 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 decking profiles, 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 decking profiles during the utilisation phase: cleaning of the WPC decking profiles 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 decking profiles 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 decking profiles in accordance with DIN EN 15534:2014, Parts 1 - 4 are used as flooring and can only be used as non-load-bearing structural elements (no general building inspection approval required). The products pose no risk to health and are technically safe. | ||

| General comment on data set | The declared products are wood-polymer decking profiles 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 decking profiles produced by member companies of the VHI. The information represents 80 % 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 illustration shows an example of the extrusion process for WPC profiles: There are two different processes for the production of WPC profiles. One is direct extrusion, in which the raw materials are added directly, and the other is a two-stage process consisting of compounding and extrusion. In this process, the raw materials are first processed into compounds and then fed into the extrusion process. Both processes are used in practice. After cooling, the surface of the WPC decking board is roughened by a brush to ensure properties such as barefoot-friendliness and slip resistance of the board. Finally, the WPC decking boards are cut to size and packed for transport. The WPC decking boards are produced in Germany and neighbouring countries. The decking boards leave the extruder with a moisture content of 0 %. Subsequently, moisture is absorbed from the environment, resulting in swelling processes and minor dimensional changes. All manufacturers involved have implemented a quality management system in accordance with /ISO 9001/. Translated with www.DeepL.com/Translator (free version) Technical data: The technical construction data listed in the following apply to all WPC decking profiles made by the manufacturers involved. Declared unit: The declared unit is defined as follows: 1 m² of installed WPC decking profiles, with the dimensions 3,000 - 6,000 mm/138 - 196 mm/21 - 38 mm and a surface weight of 18.36 kg/m², over a service life of 30 years. The composition of the WPC decking profiles results from the weighted average, depending on the production volume of the manufacturers involved. | ||
