| General comment on data set | This Environmental Product Declaration (EPD) covers ARLA Side-Hung Wooden Window with Aluminium Cladding (Two Sashes) , which are outward-opening, triple-glazed, customized building components. The dimensions (1000mm x 1000mm) are tailored to meet the customer's requirements. This is a manufacturer-specific EPD based on data from a single production site and does not represent an average or product group declaration.

The data relating to the manufacturing phase of the window was determined by UAB ARLANGA Wood. Secondary data was taken from the Ecoinvent 3.9.1. (2022) database. The database is regularly checked and thus complies with the requirements of ISO 14040/44 (background data is not older than 10 years). The background data meets the requirements of EN 15804. The scenarios included in this report represent the current practices in the relevant processes and are based on real data collected from suppliers and operational observations. They are representative of one of the most likely scenario alternatives for the product's life cycle. The general rule was followed that specific data from specific production processes or average data derived from specific processes must be given priority when calculating an EPD or Life Cycle Assessment. Data for processes that the manufacturer cannot influence or choose, were backed up with generic data. The data quality assessment (DQR) for this EPD was conducted in accordance with the requirements of EN 15804 Annex E, taking into account geographical, technical, and temporal representativeness. The DQR value for each material was calculated as the average of these three criteria, ensuring high data accuracy and reliability. Summary of DQR values for the main materials: DQR of the main materialsMaterialDQRMaterialDQRTimber - Pine2.3Glass1.7Paint1.7Aluminium for IGU2.0Metal2.0Argon gas 2.0Plastic1.7Electricity (LT)1.0Aluminium2.0Heat (Gas)2.3Rubber2.0 These values reflect a high level of data quality and ensure that the results of the life cycle analysis are reliable and compliant with the standards. All installed raw materials of the product were analysed, and the masses were determined following the allocation and cut-off requirements. Production-specific energy consumption was measured and provided by UAB ARLANGA Wood. Since the production process is quite similar for all products produced at the manufacturing site, the energy consumption, ancillary materials and production waste are allocated according to the annual production of the standard-sized elements and then declared per square meter of the product. The total annual production data is recorded to a high standard of accuracy and precision. The production waste of wood, paint and other mixed production waste is collected separately. As the product is marketed internationally, no country-specific waste scenario can be considered. Therefore, the waste scenario of PCR B (EN 17213 Appendix B.3) was adopted. Removing the window does not result in any emissions to air or soil, so the value for module C1 is assumed to be zero. Additionally, the 'Acrylic dispersion' and 'Acrylic binder' used in the product are ready-to-use materials that do not require additional water for their application or processing. These materials are delivered in their final state and used directly without modifications. Therefore, the inclusion of water in the calculations is not necessary, as it does not contribute to the product's life cycle impact. The NMD is the Netherlands’ national environmental database, providing standardised data for assessing the environmental impact of building materials. The waste scenarios used in this EPD are taken from the NMD and can be considered as representative for the respective materials. |

| Time representativeness description | All process-specific data was collected for the manufacturing year 2023, from January 1st to the 31st of December. The quantities of raw and ancillary materials as well as energy consumption have been recorded and averaged over the entire operating year 2023. |
| Technological representativeness | |
| Technology description including background system | According to the declaration, the impact for module A5 is not calculated, but based on the company's experience, it is known that there are no losses during on-site construction. The window products are completely ready for use. Energy consumption during installation can vary depending on the building's floor, type, and several other unknown parameters. This means that the impact of installation cannot be calculated due to these unknown factors. The main assembly process works. Remove from the palette. Insert into the wall of the building. Level up. Install using mounting materials. Check functionality, and adjust if necessary. |
