EPD DF1, DF1-Duo, DF39 3 General information Information about the company Description of the organisation: climowool GmbH, based in Bernburg, produces high-quality and energy-efficient insulation materials made from glass wool. Based on over 100 years of experience, Schwenk Dämmtechnik developed the glass wool “climowool” in 2011. Following the sale of the glass wool division to Knauf Insulation, climowool GmbH was founded in 2013 as an independent business unit within the Knauf Group. The product portfolio of climowool GmbH includes the comprehensive climowool clamping felt range, partition wall panels, core insulation panels, facade insulation panels, wall cassette panels and rolls as well as the climoplus pitched roof system accessories. In Bernburg, almost 180 employees produce in one of the most modern production facilities for glass wool in Europe. The Headquarter is located in Bernburg, in Germany.
EPD DF1, DF1-Duo, DF39 4 Product-related or management system-related certifications: All Knauf Insulation sites which are covered by EPD process certification system, including the sites considered for this EPD, are ISO 9001, ISO 14001, ISO 50001 and ISO 45001 certified under the scope "Design, Development and Production of Insulation Materials and Systems". Knauf Insulation supports the Ten Principles of the United Nations Global Compact on human rights, labor, environment and anti-corruption. Name and location of production site: The intended application of this product in the construction industry is within Europe. The data utilized for the production stage life cycle assessment is related to production plant(s) located in Bernburg (Germany), Krupka (Czech Republic). Address: Pod dolní drahou 110, 417 42 Krupka, Czech Republic and Weststraße 1, 06406 Bernburg (Saale), Germany. Information about Glass Mineral Wool production Knauf Insulation glass mineral wool products (GMW) are available in the form of rolls, slabs/batts and blowing wool. Typically, the density of glass mineral wool falls within the range of 10 to 85 kg/m³, and it comprises a minimum of 92% inert materials. The inert part primarily comprises recycled glass (external cullet), which constitutes up to 80% of the composition. Sand and dolomite are introduced to the mix, and the entire blend is melted together in a furnace. For slabs/batts and rolls, the residual fraction, which accounts for up to 8%, is composed of bio-based binder components. At Knauf Insulation, the binder used for the glass mineral wool products is the ECOSE® Technology binder. ECOSE® Technology contains no added formaldehyde or phenol. Additionally, this binder is derived from rapidly renewable natural raw materials, specifically plant starch. Blowing wool insulation is a non-bonded, virgin fibrous insulation material, manufactured as a loose-fill product without the use of binders. In contrast, rolls and slabs/batts of insulation are bonded and cured in an oven.

EPD DF1, DF1-Duo, DF39 6 System diagram: Description of system boundaries: The system boundary of the EPD follows the modularity approach defined by the EN 15804:2012+A2:2019. The type of EPD is cradle-to-grave. For a comprehensive assessment, it is strongly recommended to consider the results from all the modules. Relying exclusively on Modules A1-A3 may lead to incomplete conclusions. A comprehensive list and detailed explanations of each stage within the EPD are available as follows. The product stage (A1-A3) includes: - A1 – raw material extraction and processing, processing of secondary material input (e.g. recycling processes), for the processing of recycled glass into cullet, only the use of electricity is considered, - A2 – transport to the manufacturer and - A3 – manufacturing This includes provision of all materials, products and energy, packaging processing and its transport, as well as waste processing up to the end-of-waste state or disposal of final residues during the product stage. The LCA results are presented in an aggregated format for the product stage, where modules A1, A2, and A3 are consolidated into a single module, denoted as A1-A3. Product Parameters Value Glass mineral wool weight 1.2 kg Area 1m² Thickness 100 mm Volume 0.1m3 Facing/ coating weight 0 kg Packaging – PE film 0.02 kg Packaging - Wooden pallet 0.05 kg The construction process stage includes: - A4 - transport to the construction site and - A5 - installation into the building. The transport to the building site (A4) and installation (A5) included in this LCA use the following parameters: Parameter Value Average transport distance (truck) 600 km Type of fuel and vehicle used for transport (truck) Truck Euro 6 (28 – 32 t / 22 t payload). Truck capacity utilisation (including 30% of empty returns) 26 % of the weight capacity Loss of materials on site 2% Packaging – PE film 40 % recycled, 60 % incinerated Packaging - Wooden pallet 40 % recycled, 60 % incinerated The treatment and the transport of the packaging waste after the installation of the product (A5) has been considered. The Use stage (B1-B7) includes: - B1: Use - B2: Maintenance - B3: Repair - B4: Replacement - B5: Refurbishment - B6: Operational Energy Use - B7: Operational Water Use Once installation is complete, no actions or technical operations are required during the use stages until the end of life. Therefore, the mineral wool has no impact (excluding potential energy savings) on this stage. The end-of-life stage includes: - C1 – de-construction, demolition, - C2 – transport to waste processing, - C3 – waste processing for reuse, recovery and/or recycling and - C4 – disposal. This includes provision of all transport, materials, products and related energy and water use. The common manual dismantling impact of insulation is considered as very small and can be neglected in C1. Although glass mineral wool products from Knauf Insulation are partly recycled at their end-of-life, an established collection system does not yet exist in all countries. Therefore, the assumption chosen in this study,
EPD DF1, DF1-Duo, DF39 7 100% landfill (C4) after the use phase, is the most conservative approach. Parameter Value Disposal type (mineral wool) 100% landfill Average transport distance waste (C2) 50 km Type of fuel and vehicle consumption or type of vehicle used for transport. Truck-trailer, Euro 6, 34 - 40t gross weight / 27t payload capacity/ 40 L for 100 km. (if 100 % utilization). Truck capacity utilization 50 % of the weight capacity Module D includes reuse, recovery and/or recycling potentials. According to EN 15804:2012+A2:2019 any declared benefits and loads from net flows leaving the product system not allocated as co-products and having passed the end-of waste state shall be included in module D. The benefits considered in module D originate from packaging recycling or incineration. Recycled material The mineral wool scrap generated during the manufacturing process is recycled internally and fed back into the mineral wool production process at multiple stages. Recycled content average for the considered plant(s) for this product was calculated at 73% in 2022 according to the cullet market availability. The calculation is taking into account the % of secondary materials from external supply input into the batch against virgin raw materials supply. The external waste considerations and the calculation methodology applied are also in accordance with the ISO 14021 standard. Additional information: All raw materials used in the manufacture of the declared product, the required energy, water consumption and the resulting emissions are considered in the LCA. As a result, recipe components with a share of less than 1% are included. All neglected processes contribute less than 5% to the total mass or less than 5% to the total energy consumption. For information, the impact of the glass mineral wool plant construction or manufacturing equipment is not taken into account in the life cycle assessment. Allocation criteria with by-products (mineral wool for ceiling tiles) are based on cost. Materials required for fixing and installation are not included in the scope of this LCA. The impact of any additional construction products or materials not included in this EPD should be accounted for at building level. Regarding installation, this EPD only includes the environmental impacts relating to the product itself, such as material losses and packaging disposal. Knauf Insulation adopts a conservative approach in its EPDs. Conversion to mass and specific thicknesses The results of this EPD apply to a thickness of 100 mm, with an R-value of 2.5 m²K/W. Multiplication factors for the primary product thicknesses are provided to calculate the environmental performance for each thickness in the table below. To adjust the results for all indicators across all modules to different thicknesses, multiply the values in this EPD by the corresponding conversion factor in the table. For thicknesses not listed, conversion factors can be calculated by dividing the product thickness by 100 mm, as the results scale linearly. Product thickness (mm) Thickness Conversion factor 150 1.5 The conversion factor used in this EPD involves multiplying the results by 0.87 to obtain Environmental Impact Indicator results for 1 kg. Please note, an insulation product should always be defined by both its thickness and R-value. Focusing only on the product's weight could result in misinterpretations.

13 EPD DF1, DF1-Duo, DF39 LCA interpretation ENVIRONMENTAL IMPACTS All impact categories except the Abiotic Depletion Potential for Non-Fossil Resources (ADP- minerals &metals) and the Depletion Potential of the Stratospheric Ozone layer (ODP) are dominated by the production. This is mainly due to the consumption of energy (electricity and natural gas) during the production of glass mineral wool. The Global Warming Potential (GWP-total) is clearly dominated by the production, mostly due to energy consumption but significantly reduced through the use of electricity from renewable sources. The Depletion Potential of the Stratospheric Ozone layer (ODP) is mostly influenced by the manufacturing phase (module A1-A3) and significantly influenced using electricity. The Acidification Potential (AP) is also dominated by the production due to the process’s emissions and the electricity consumption. Most of the impact is by emissions of sulphur dioxide, ammonia and nitrogen oxides. The Eutrophication Potential Fresh Water (all EP indicators in total) is mainly influenced by production due to emissions from the curing oven, furnace and other unit processes. The glucose for the binder production also has an impact because of crops fertilizers use. The Formation Potential of Tropospheric Ozone (POCP) is dominated by emissions from the manufacturing processes (including energy use) and raw materials. The Abiotic Depletion Potential for Non-Fossil Resources (ADP- minerals &metals) is dominated by the raw materials production. The Abiotic Depletion Potential for Fossil Resources Potential (ADP-fossil) is dominated by energy consumption for the production. The packaging (plastic) and the binder have also a non-negligible impact. The variation in Global Warming Potential (GWP) results (A1-A3) between the manufacturing sites covered by this EPD and the average results is ±2.0%. Berburg plant has a lower environmental impact compared to Krupka plant due to variations in energy and raw material consumption. -20%0%20%40%60%80%100%GWP-total (kg CO2 eq.)ODP (kg CFC 11 eq.)AP (mol H+ eq.)EP-freshwater (kg P eq.)POCP (kg NMVOC eq.)ADP-fossil (MJ)ADP-minerals&metals (kg Sb eq.)A1-A3A4 TransportA5 InstallationC2 TransportC4 DisposalD Credit
14 EPD DF1, DF1-Duo, DF39 RESOURCES USE Total Use of Non-Renewable Primary Energy Resources (PENRT) is dominated by the production of glass mineral wool products (especially due to the energy consumption) and with little influence of raw materials, binder and packaging. Total Use of Renewable Primary Energy Resources (PERT) is dominated by the binder (bio-based), the production and the packaging (wooden pallets). For the Use of Secondary Material (SM), there is a lot of external cullet used into the batch process (recycled glass from windows, bottles and jars.
