| Use advice for data set | Scope: The lifecycle assessment shown in the EPD relates to the lifecycle of unfaced or uncoated synthetic resin-bonded stone wool insulating material in the low bulk density range from ROCKWOOL. The stone wool is produced in the Gladbeck, Neuburg and Flechtingen works in which the production data for 2016 was recorded. The key LCA results for the facings are to be found in the Appendix. This was produced and verified in 2015. The LCA thus represents 100% of the stone wool produced by ROCKWOOL. This document is a translation from the German Environmental Product Declaration into English. It is based on the German original version EPD-DRW-20180065-IBC1-DE. System boundary: EPD type: Cradle to grave with options The LCA includes the lifecycle phases of stone wool manufacture (A1-A3), transport to the building site (A4), the recycling and disposal of packaging and offcuts which accrue during installation (Module A5) and the end of life phase of the stone wool (Modules C1 to C4). Benefits as a result of thermal recycling of packaging were assigned to Module D. Specifically, the following processes were included in the production stage (A1-A3): Provisioning processes of pre-production and energy Transport of raw materials and pre-products to the works Manufacturing process in the factory including energy-related uses, disposal of accruing residual materials and emissions Manufacture of packaging Secondary materials which enter the system which have already reached the end of the waste characteristic before they are delivered were included free of loads but including the transports necessary for delivery. Waste used as alternative fuel also enters the system without loads. In accordance with the polluter-pays principle, the transport of this waste to the factory has to be added to the preceding product lifecycle and was not included in the LCA. The quantities of packaging material included are annual usage or purchase quantities in which pallet rotations are already included. When selecting recycling processes for the calculation it was ensured that CO2 stored in den packaging materials is released as an emission during the recovery process. Emissions and loads as a result of the recycling of packaging are allocated to Module A5 and resultant benefits were added to Module D. The recycling and disposal of the stone wool at end of life include truck transport back to the factory of manufacture or a dumping ground (C2) and also the final disposal of the corresponding share (C4). The quantity of stone wool waste delivered from building sites which was deployed in the relevant year was included as the recycling quantity at end of life which is why no net quantities for recycling result and thus no benefits can be included in Module D. The scope of investigation of the facings covers Modules A1-A3, A4, A5, C1 to C4 and D. Since no additional packaging is included for the facing, no environmental loads or benefits ensue for facings in Modules A5 and D. | ||

| General comment on data set | The definition of mineral wool (stone or glass wool) in accordance with German hazardous substances law (Chemicals Prohibition Order, Hazardous Substances Ordinance) is as follows: "Artificial vitreous (silicate) fibres with random orientation and a mass content of more than 18 % of sodium, potassium, calcium, magnesium and barium oxides". Stone wool insulation is a fibre insulation material. A major component is stone wool insulation fibres. These are monofilament artificial mineral fibres of a non-crystalline structure which are obtained from a silica-based molten mass. The mean fibre diameter is 3-6 µm. The fibres can be several centimetres in length. The artificial resin-bonded stone wool insulation described in this declaration is manufactured in the form of low-density sheets, mats or rolls (up to 60 kg/m3). The products are supplied in thicknesses of between 20 mm and 350 mm, for example as compression-proof sheets, treadable two-layer sheets or felting and rolls. For certain application areas, the insulation is provided with a functional facing on one or both sides. | ||

| Technology description including background system | General information: Stone wool insulation is a fibre insulation material. A major component is stone wool insulation fibres. These are monofilament artificial mineral fibres of a non-crystalline structure which are obtained from a silica-based molten mass. The mean fibre diameter is 3-6 µm. The fibres can be several centimetres in length. The artificial resin-bonded stone wool insulation described in this declaration is manufactured in the form of low-density sheets, mats or rolls (up to 60 kg/m3). The products are supplied in thicknesses of between 20 mm and 350 mm, for example as compression-proof sheets, treadable two-layer sheets or felting and rolls. The environmental impacts of the facings are listed in the Appendix and are to be added to the LCA results in this declaration as described in the EPD. Production: Diabase or basalt as well as cement-bonded bricks are melted using coke as the energy carrier in a cupola furnace at approximately 1,400-1,500°C and frayed out by means of roller spinning. Immediately afterwards, mineral oil and binding agent are sprayed on as a watery solution. The binding agent serves to guarantee binding and dimensional stability and the mineral oil to reduce dust and to increase hydrophobisation. The bonding agent also contained in the watery solution supports the adhesion of the binding agent to the fibres. In the collecting chamber, the raw wool is placed on transport conveyors under negative pressure. Optionally, facings can then be applied. (The corresponding environmental impacts for this are specified in the Appendix.). The possibly faced raw fleece is fed into hardening furnaces in which hot air at 200-300°C is sucked through the wool mass whilst the binding agents link to thermosets. Finally, the product is shaped using saws. Environment and health during manufacturing: Exhaust air produced during manufacture is mechanically filtered and most of it thermally combusted. The heat released is used to pre-heat the blast air via heat exchangers. The separated dust is reused as a raw material. Waste water produced during manufacturing is mainly processed internally and returned to production. Declared lifecycle stages: The LCA results cover all lifecycle stages including the provisioning processes of raw materials and intermediates as well as the processing of secondary materials used as inputs (e.g. recycling processes), their transport to the factory and the production including all ancillary materials, energy inputs as well as the waste treatment and disposal of residual wastes accruing during production. The modules A1, A2 and A3 are aggregated to Module A1-A3. Further, the modules A4 (transport to the building site), A5 (assembly), C1 (deconstruction), C2 (transport), C3 (waste processing), C4 (disposal) and D (benefit) are declared. Technical data: Thermal conductivity [W/(mK)]: 0.032 to 0.050 [W/(mK)] according to /DIN EN 13162/ respectively /DIN EN 14303/]; Design value for thermal conductivity: [W/(mK)]: 0.033 to 0.049 [W/(mK)] according to /DIN 4108-4/; Water vapour diffusion resistance factor μ according to /DIN EN 12086/: µ = 1; Water vapor diffusion equivalent air layer thickness = μ x component thickness [m] (this would be 1 for a thickness of 1 m) Bulk density according to. /DIN EN 1602/: ≤60 kg/m³; Compressive stress (at 10 % deformation) according to /DIN EN 826/: 0,5 to 5 kPa; Sound absorption coefficient αS depending on the frequency is to be found in the data sheets for the relevant products. Declared unit: The declaration relates to the lifecycle of 1 m3 stone wool insulation material produced by DEUTSCHE ROCKWOOL GmbH & Co. KG . The products are manufactured in three factories which exhibit no technology differences for stone wool manufacture. The average was formed on the basis of production quantities. The bulk density of the declared products can be up to 60 kg/m3. An average bulk density of 39 kg/m3 is determined for the low-density stone wool insulation for which the LCA results are shown below. The transfer of the results to other bulk densities is possible via a linear scale.
