| Use advice for data set | Scope: The EPD refers to all products in the EJOT portfolio that are used in rear-ventilated facade systems. The declared product is manufactured in the plants Ciasna in Poland, Tambach in Germany and Dozwil in Switzerland. The data basis is the year 2012. The declared results apply to a length of 120 mm, for all other lengths the results can be extrapolated using the formula given. System boundary: Type of EPD: Cradle to factory gate - with options. The environmental product declaration refers to the production stage (module A1-A3), the disposal stage (modules C1-C4) as well as Credits and loads outside the system boundary (module D). In the production stage, the procurement of raw materials including the corresponding upstream chains, the necessary procurement transports to the plants as well as the energies required for the production of the anchor systems are considered. The country-specific electricity mix was modelled for each of the plants. The material composition and the energy demand of the declared anchor systems were calculated according to their production shares in each plant. In the disposal phase, the dismantling of the anchor systems (Module C1), the transport to waste treatment (Module C2), the waste treatment (Module C3) and the landfilling of the plastics (Module C4) are considered. Avoided burdens from the recycling of metals are reported in Module D. For this purpose, only the net scrap quantities are considered. | ||

| General comment on data set | Connecting, fastening and anchoring elements of EJOT Baubefestigungen GmbH are finished products consisting of a plastic sleeve and an expansion element made of steel or stainless steel, only a plastic element or only one or more steel parts. The declaration applies to all anchoring, connecting and fastening elements mentioned below, which preferably can be used in the rear-ventilated facades system or in conjunction with the rear-ventilated facades system. | ||

| Technology description including background system | Raw materials/ Ancillary materials: The main basic materials or primary products for the anchoring and fastening products from the ventilated curtain wall system are: - Steel (mass 75-80 %) - PE HD Polyethylene high density (mass 15-17 %) - PA polyamide (3-6 %) Dyes (< 1 %). The auxiliary materials and additives are contained in the plastic granulate. In the EJOT production companies, no auxiliary materials and additives are used in production. Production: The plastic anchor sleeves are manufactured using conventional injection moulding techniques. For this purpose, an injection moulding machine is used to plasticise the respective plastic in an injection unit and inject it into an injection mould.The cavity of the mould determines the shape and surface structure of the finished part (here plastic anchor). Screws: The vast majority of screws and fasteners are produced by non-cutting cold forming. The cold extrusion process: The starting material is delivered as "wire" wound on spools and uncoiled, straightened and, if necessary, reduced to the desired diameter in equipment upstream of the presses. Modern cold extrusion presses work in several stages, i.e. several operations are linked in succession per stroke, e.g. preforming the screw head, upsetting, deburring and reducing the threaded part. In the subsequent process, the threads are rolled onto the reduced threaded parts by thread rolling machines with flat dies or rolling and segment tools without cutting. Preferably cold extrusion presses with integrated thread rolling machines are used. Technical data: The technical data are given as examples and representative for each of the 3 average declared products. Declared unit: The declared unit is an average anchor system for use in 1 m²rear-ventilated facades with a specific length of 120 mm, consisting of four individual systems. "Average" describes all produced anchor types of the system on average according to production shares weighted on the basis of a parameter analysis. This means that a hypothetical anchor system is calculated, which represents the entire rear-ventilated facades system. To convert the declared unit to kg, the weight per system is given.
