| Use advice for data set | Scope: This ARGE EPD covers hardware systems for sliding doors, sliding corner doors, sliding folding doors and sliding gates used for buildings as well as mechanisms used to support doors of varying materials and allow their opening and closing by a sliding action. It does not include sliding folding windows or door height windows. The reference product used to calculate the impact this product group has on the environment is an item of sliding door hardware composed primarily of aluminium and has been selected for the LCA (Life Cycle Assessment) because it is the product with the highest impact for 1 kg of product. A validity scope analysis has also been carried out to determine the limiting factors for sliding door gear covered by this EPD. In a preliminary study (simplified LCA), it has been confirmed that this EPD represents the worst-case condition and it can therefore be used to cover all sliding door hardware manufactured in Europe by ARGE member companies. System boundary: Type of the EPD: "cradle to gate with options, with modules C1 – C4, and module D (A1-A3, C1-C3, D and additional modules)" The analysis of the product life cycle includes the production and transport of the raw materials, the manufacture of the product and the packaging materials which are declared in modules A1-A3. Losses during production are considered as waste and are sent for recycling. No recycling processes are taken into account except for transport and electricity consumption for grinding the metals. When recycled metals are used as raw material only their transformation process is taken into account and not the extraction of the raw material. A4 module represents the transport of the finished sliding door gear to the installation site. There is no waste associated with the installation of the product. The A5 module therefore represents only the disposal of the product packaging. The End-of-Life (EoL) stages are also considered. The transportation to the EoL disposal site is taken into account in module C2. Module C4 covers the disposal of the locks. Module C3 covers the recycling of the individual elements according to European averages, with the remaining waste divided between incineration and landfill. Such a mixed scenario is declared due to the complex material mix of the product and the dependency of the EoL-route on the EoL-route of the product the sliding door hardware has been integrated into. In practice, the end of life has been modelled as follows: when a material is sent for, recycling, generic transport and electric consumption of a shredder is taken into account (corresponding to the process Grinding, metals). Only then, is the material considered to have attained the end-of-waste state. each type of waste is modelled as a transport to the treatment site with a distance of 30 km. Parts sent for recycling include electricity consumption (grinding) and a flow (Materials for recycling, unspecified). | ||
| Technical purpose of product or process | These products are designed to be integrated into door and gate assemblies consisting of various materials and used for various applications. Their purpose is to ensure the fastening of the door or gate and to open and close it safely. They may be used for either interior or exterior doors or for gates. | ||

| Technology description including background system | Sliding hardware is normally manufactured in 3 steps: 1. prefabrication of semi-finished products This step may include surface treatment at the factory or at external manufacturers. 2. pre-assembly of the components (in the factory) 3. final assembly (factory premises) Technical data: Ideally, products should comply with a suitable technical specification. EN 1527:2019+A1:2021, Building hardware – Hardware for sliding doors and folding doors – Requirements and test methods and EN 13126-15:2019, Building hardware - Hardware for windows and door height windows - Requirements and test methods - Part 15: Rollers for horizontal sliding and hardware for sliding folding windows are examples of such specifications and some products will comply with them. The relevant grading structure is shown in the following table: Declared unit: The declared unit for all products covered by ARGE EPD is 1 kg (of product). Since individual products will rarely weigh exactly 1 kg it is necessary to establish the exact weight of the product and then use this as a correction factor to determine the true values for 1 kg of product in the tables (Section 5). | ||
