| Use advice for data set | Scope: This Environmental Product Declaration (EPD) is valid for Alpha sectional doors of the type ALU 40. The production facilities are located in Didam (NL). The life cycle assessment is representative for the products introduced in the declaration for the given system boundaries. System boundary: Type of the EPD: cradle-to-gate. The production of the materials (steel, plastics, aluminiums, coating etc.) and also the motor-parts and other electronic components are modelled in A1. The transportation (road and sea) from the suppliers to Alpha deuren is modelled in A2. The assembly of the doors (energy use) and the packaging (including the production and transportation of the packaging materials) is modelled in A3. The generation of electricity and heat is modelled in A3. For the option coating is also the coatingprocesses and the emissions of non-methane volatile organic compounds to air modelled in A3. Production waste from A3 is modelled following the Dutch defaults for waste scenario’s (see 4.1.3). This modelling results in components for reuse, materials for recycling. According to EN 15804 (CEN 2013) the end-of-life system boundary of the construction product system is set where outputs of the system under study, e.g. materials, products or construction elements, have reached the end-of-waste state. Therefore, waste processing of the material flows (e.g. undergoing recovery or recycling processes) during any module of the product system (e.g. during the production stage, use stage or end-of-life stage) are included up to the system boundary of the respective module. For all phases A1-A3 also processing up to the end-of-waste state or disposal of final residues not leaving the factory gate with the product, are included. For the option paint, there are materials for energy recovery. Waste of the paint will combusted and energy will be recovered in an incineration plant. This is modelled in module A3. |
| Technical purpose of product or process | Alpha industrial sectional doors are used in private homes, agricultural buildings, industrial buildings and non-residential buildings. For the application and use the respective national provisions apply. The space-saving industrial sectional door can be fitted to both outdoor and indoor walls. The ALU 40 sectional door is assembled from aluminium panels with a working height of between 366 and 732 mm. When the door is opened, the sections slide back under the roof. The weight of the door leaf is balanced using torsion springs to allow manual operation. In addition to the standard lift track system, high lift, vertical lift, roof following and low headroom systems are available. The industrial sectional door complies with /EN13241-1/ (products without smoke control and fire resistant characteristics). |

| General comment on data set | Sectional doors, type ALU 40, constructed from extruded aluminium sections fitted with 20 mm PMMA (polymethyl methacrylate) double glazing. The panels are 40 mm thick and available in heights varying between 366 and 732 mm. The horizontal seal retaining profile on the top section is made from aluminium, or supplied with a spray-painted finish (optional). These ALU sections can be combined with insulated, steel-skinned ISO panels. Surface treatment The panels are supplied as standard with an anodised finish or painted with primer in RAL 9002. They can also be painted in a RAL colour chosen by the customer. This option is covered in this EPD. Track systems are made of 1.7 mm thick, closed steel angle profiles fitted with roller tracks made of 1.7 mm thick galvanised steel. The door hardware is attached using electrolytically galvanised self-tapping screws with a knurled integral lock-washer. The rollers feature nylon wheels and an 11 mm galvanised steel shaft. The door leaf is balanced via torsion springs and hung on steel cables with a safety factor of 6. Manually operated doors are supplied with a plastic handle and foot plate in the bottom section and a steel shoot bolt, or an optional cylinder lock. Draft seals are fitted around the periphery of the door leaf: top, side and floor seals made from EPDM (ethylene propylene diene monomer rubber) seals between the panels made from EPDM Operators The industrial sectional door can be operated manually by pull cord or chain hoist. Optionally it can be supplied with an electric drive. This option is covered in the EPD for Sectional door ALU40 with electric drive. Safety emergency chain hoist and emergency drive disconnect up to operator height in the case of electric drives cable break safety and/or slack cable safety spring break safety lift-up prevention finger pinch safety Wicket doors The industrial sectional door can be supplied with an integral wicket door or a pass door next to the sectional door. This option is covered in the EPD for Sectional door ALU 40 with wicket door. |

| Technology description including background system | All materials necessary to produce Alpha sectional doors are received and stored in a central warehouse, from where they are internally distributed to the different production areas. Each ALU 40 door is then made to order. In one production area, the door leaf is produced. Activities consist of sawing, mounting, boring and assembly. The panels are supplied as standard with an anodized finish or painted with primer in RAL 9002. The panels can also be painted in any other RAL colour chosen by the customer. After the door leaf has been manufactured and checked, it is internally transported to a different production area, where the rail system, springs and boxes are produced. The rail system is produced by roll formers and is then assembled. Parts needed to mount the door are collected in a box by following a "pick to light" system. After checking for completeness, the door leaf is combined with the rails, springs, boxes and other loose parts. The complete package is then mechanically wrapped in foil and is ready for transportation to the customer. Technical data: Technical details based on a sectional door ALU 40 for an opening of 3800 x 3500 mm (W x H). The presented data comply with those given in the DoP. The different values have been tested by TÜV Nord. Declared unit: The declared unit of the door is one m2 door. The data are presented per standard door with a width of 3800 mm and a height of 3500 mm. The dimensions for the standard door are chosen because the doors were most frequently sold in these dimensions in the year of 2015. |
