Blowing wool insulation EPD S-P-01756 3 About the company Knauf Insulation has more than 40 years of experience in the insulation industry and is one of the most respected names in insulation worldwide. At Knauf Insulation, we are committed to helping our customers meet the increasing demand for energy efficiency and sustainability in homes, non-residential buildings and industrial applications. As the only manufacturer of both Glass and Rock Mineral Wool, we are uniquely placed to provide the best insulation solution for each application. We offer a wide range of insulation solutions for all applications in commercial and residential buildings, for both new build and refurbishment projects, in addition to solutions for HVAC, industrial applications and fire protection, green roofs and bespoke applications. COMPANY CERTIFICATIONS All Knauf Insulation sites, including the manufacturing facilities for products covered by this EPD, are ISO 9001, ISO 14001, ISO 5001 and OHSAS 18001 certified under the scope "Design, Development and Production of Insulation Materials and Systems". PRODUCTION SITES Data used for the product LCA were collected from Knauf Insulation (Northern Europe)'s two glass insulation manufacturing facilities in the UK: Knauf Insulation, Stafford Road, St Helens, Merseyside Knauf Insulation, Cwmbran, Torfaen, Wales About glass mineral wool production Glass mineral wool insulation is available in two forms: Glass Mineral Wool (GMW) products contain binder and are manufactured in the form of slabs and rolls. Blowing wool products contain no binder for loose-fill applications. In the manufacturing process, recovered waste glass is melted together with other raw materials needed to achieve glass of the target composition. As molten glass leaves the furnace, it is cooled and formed into glass fibres. This is transformed directly into the blowing wool product. For mineral wool products, binder is then applied as a solution prior to the forming and oven-curing of the final product Both GMW and blowing wool are produced at Knauf Insulation (Northern Europe)'s glass insulation manufacturing facilities in the UK. This EPD concerns blowing wool products compliant with the requirements of EN 14064. These are manufactured in the form of flocks of unbound glass mineral wool; the production process for blowing wool is shown in the figure below.
Blowing wool insulation EPD S-P-01756 4 Product information PRODUCT DESCRIPTION Blowing wool comprises over 99% inert material. This inert content comprises recycled glass (external cullet, up to 80% of the composition) with other mineral raw materials - mainly sand and dolomite. The remaining fraction (≤1%) comprises anti-static, water repellent and dust-suppressing additives. Glass blowing wool is used for thermal insulation in buildings. The principal performance characteristic of thermal insulation is its thermal conductivity (Lambda, λ). The product is mainly marketed in the Northern Europe, particularly the UK and Scandinavia. RECYCLED MATERIAL The external cullet content applied in the LCA for this EPD was taken from 2018 usage data for Cwmbran and St Helens factories. PACKAGING AND TRANSPORTATION All glass insulation products are compressed when packed to optimise their transport to customers. USE AND MAINTENANCE The product does not require maintenance or replacement. In normal conditions of use, the product is not visible in either internal or external areas, and will not be in contact with water. END-OF-LIFE The product may be disposed of as a non-hazardous material, EWC code 17 06 04. UN CPC Under the UN CPC classification system v2.1, Knauf Insulation (NE) mineral wool insulation products are classified CPC 37990.

Blowing wool insulation EPD S-P-01756 7 LCA information This section of the EPD records key features of the LCA on which it is based. DECLARED UNIT The declared unit is 1m2 at 100mm thickness. The applicable thermal conductivity is 0.037 - 0.042 W/mK. Indicator values are declared for product with density 17 kg/m3. If indicator values for other densities are required, they may be obtained by linear extrapolation of these values. SCOPE AND SYSTEM BOUNDARIES The system boundary of the EPD is defined using the modular approach set out in EN 15804 as shown in the table below. This a cradle-to-gate with options EPD.

It includes the transport distance and the relevant transport mode. Module A5 covers installation of the product in the building. Blowing wool is blown into place using compressed air; therefore for blowing wool products, A5 includes energy use as well as product wastage at 2% and management of product packaging after use. These modules are included in the LCA using scenarios, except for energy used to install blowing wool in module A5, which is modelled using data collected by Knauf Insulation for installation in different contexts within the building.

DATA SOURCES AND DATA QUALITY The collected data covered all raw materials, consumables and packaging materials; associated transport to the manufacturing site; process energy and water use; direct production wastes; emissions to air and water. ALLOCATION In the background data, the ecoinvent default allocation is applied to all processes except those in which secondary materials are used, where the "cut-off" allocation is applied. This ensures that secondary materials are free of upstream burdens that arise prior to their reaching the "end of waste" state; this is in accordance with the PCR and also Section 6.3.4.2 of EN 15804. Following ISO 14044, the overall process is subdivided as far as possible, so that flows dedicated to a particular product type are fully assigned to that product type and the need for allocation is minimised. ASSUMPTIONS AND ESTIMATES Inputs to and outputs from the system are accounted for over a 100-year time period; long-term emissions are therefore omitted from the impact assessment part of the LCA. The "primary energy used as material" indicators (PERM; PENRM) are calculated using - as characterisation factors - published values for constituent materials which can yield energy on combustion, where available, and from published calorific values where PEM values are not available. Calculations of PE(N)RM are based on a feedstock energy content of 47MJ/kg for plastic packaging film, and 16MJ/kg for wood. "Primary energy as fuel" indicators (PENRE, PERE) are calculated as the total primary energy demand minus primary energy used as material. The secondary material indicator counts recycled glass in the product only. TIME REPRESENTATIVENESS Data used for this LCA were collected following guidance in ISO 14044:2006 and cover the 12-month period January 1 - December 31 2018.

Blowing wool insulation EPD S-P-01756 16 LCA interpretation Modules A1 - A3 are the most significant across the whole life cycle. Knauf Insulation's own processes make the largest contribution to the indicator totals for almost all environmental impact categories, through energy use and emissions from the glass-making process. Waste indicators, and the indicator values obtained for ODP and water use should be used with caution; all are subject to uncertainties in data or method which limit the scope for their use for comparison with other products or with other EPD produced using background data from different sources.
