| Use advice for data set | Scope: This declaration is an association EPD. It covers all constructional forms for PVC windows which comply with the stated characteristics. These are both blocked and bonded window designs and different profile reinforcement and surface design variants. Data from the production plants of the following system suppliers and window manufacturers was included: aluplast – Ettlingen (DE) Deceuninck – Bogen (DE), Calne (GB), Hooglede- Gits (BE), Jasin (PL), Roye (FR) GARGIULO – Nehren (DE) GEALAN – Bukarest (RO), Guopstos (LT), Rzgów (PL), Tanna (DE) hapa – Herrieden (DE) Internorm – Sarleinsbach (AT), Traun (AT) profine – Berlin (DE), Marmoutier (FR), Pirmasens (DE) REHAU – Srem (PL), Wittmund (DE) Salamander –Türkheim (DE), Wloclawek (PL) SCHÜCO – Weißenfels (DE) TMP – Bad Langensalza (DE) VEKA – Burgos (ES), Burnley (GB), Sendenhorst (DE), Skierniewice (PL),Thonon-les-Bains (FR)The weighted mean of the data from eleven member companies with 27 production sites in nine countries was used as a database for manufacturing the plastic profiles. The production quantity thus recorded corresponds to approximately 80% to the European production of the profile manufacturers who are organised in the EPPA, GKFP and QKE associations. This association EPD can be used by the member companies of the three EPPA, GKFP and QKE associations as well as window manufacturers who use this company’s plastic profile systems. System boundary: The complete lifecycle from the cradle to the grave is examined for the declared unit. The production stage (Modules A1–A3), the construction stage (A4, A5), the use stage (B1, B2), the disposal stage (C1–C4) and benefits and loads beyond the system boundary (D) are relevant but not the further modules of the use stage (B3–B7). Manufacturing The aggregated illustration in the form of A1–A3 is used for manufacturing. This includes the provision of raw materials and energy, the production of steel reinforcement, glazing, hardware and PVC profiles, transport of the components to the window manufacturer, the energy consumption needed for this and accruing production waste. The consumption for heating the production plants and also the attached rooms is also specifically included. However, investment goods (machines, buildings, etc.) remain ignored. Transport from the window-maker to the construction site is included in Module A4 and also the auxiliary and operating materials used for installation and the disposal of packaging waste in Module A5 in accordance with DIN EN 17213. Use phase The transmission heat losses during the use phase is included in Module B1 and the replacement of window components mentioned in 2.12 in Module B2. Disposal All processes which relate to the removal, dismantling or breaking of the window out of the building and which are not to be regarded at building level was calculated into Module C1. Redistribution transports from the construction site to waste treatment fall in Module C2. Waste management processes, especially energy recovery from waste, are included in Module C3. This also includes sorting for recycling. Disposal and also thermal waste treatment land in Module C4. Credits Finally, Module D shows the reuse, recovery and recycling potentials beyond the system boundary. | ||

| General comment on data set | Single-sash window 1.23 m x 1.48 m with PVC-U frame profiles, triple insulating glass unit and tilt-turn hardware. Steel, aluminium or glass fibre extruded into the PVC material can be used as reinforcement in the PVC profiles. The profile surface can be made with different finishes: uncoated white, covered with PVC foil, covered with PMMA (polymethylmethacrylate), coated or fitted with a separate aluminium covering shell. This results in white, coloured, smooth or structured surfaces. The gaskets consist of soft PVC, EPDM (ethylene-propylene-dien monomer) or TPE (thermoplastic elastomere); the hardware is mainly made of steel. The average window for this EPD is the white steel-reinforced basic variant. However, the inputs/outputs determined from the production quantities are included for profile production, whereby all surface finishing processes which are actually performed at the plants are included. This EPD declares the average environmental quality for the PVC windows of the member companies of the EPPA, GKFP and QKE associations. Window manufacturers who use this company’s plastic profile systems can also make use of the declaration. Detailed product data is available from the respective manufacturers’ specific descriptions. | ||

| Technology description including background system | As shown in Fig. 2-1 plastic windows are made of the following components: PVC frame profiles with gaskets and if necessary reinforcement, insulating glass unit and hardware. Fig. 2-1: Schematic diagram of the manufacture of a window unit The PVC profiles are produced in an extrusion process from a mixture of PVC powder and additives. The latter protect the PVC against damage during processing and give the profile the necessary characteristics such as impact resistance, colour, and weather resistance. The PVC powder for producing the frames is a widely available mass plastic and is manufactured by polymerisation. Due to its chemical structure, PVC contains a considerable proportion of the halogen chlorine. Coloured surfaces can be produced by fitting an aluminium covering shell, applying a foil, coating or by co-extrusion with a PMMA layer. Gaskets are either attached to the window profile in a co-extrusion process during extrusion or rolled in subsequently. The window profiles are supplied to window manufacturers in standard lengths. There they are sawn to the lengths required for respective windows. As far as necessary, steel reinforcement is pushed in and screwed in place. The profiles are then welded, the hardware attached and the glazing and glazing beads inserted. The steel to produce the hardware is mainly manufactured from iron ore in a furnace process through reduction with coke. The raw material base for the manufacture of the glazing is quartz sand and the addition of various fluxing and oxidation agents (soda ash, sodium sulphate, potassium carbonate, etc.). In a further processing step, the melted raw glass is placed in a tin melt from which a flat glass ribbon is continuously drawn (float glass process). Quality assurance GKFP e.V. member companies are subject to external quality control as part of voluntary self-commitment. Those plastic window profile systems which may be labelled with RAL-GZ 716 are listed on the association’s website at gkfp.de/en: www.gkfp.de/en/product-overview/profile-systems-with-ral-quality-mark Those window manufacturers which use the RAL quality mark in accordance with RAL-GZ 695 are also subject to external monitoring. A list is available on the Gütegemeinschaft Fenster, Fassaden und Haustüren e.V. website (window.de/guetegemeinschaft-fenster) at: www.ral-fachbetriebe.fenster-können-mehr.de. Technical data: The figures and/or classes shown in the following table apply to the reference on which this EPD is based. Far higher classes are being achieved depending on the execution of the frame, hardware, gaskets and insulating glass unit. Declared unit: The declared unit is 1 m2 of window area on a reference window (similar to DIN EN 14351-1 and DIN EN 17213). Its frame area ratio FF in relation to the overall surface area is around 33%. | ||
