Environmental indicatorsUnderstanding the methodological approach

Objectives Knauf Insulation is committed to making information about the environmental impact relating to products it places on the market available upon request. The format for presenting this information can either be a standard verified EPD or a simpler Environmental Fact Sheet based on a verified EPD.

The results are based on the LCA of rock mineral wool insulation products produced by Knauf Insulation RMW manufacturing plants.

The areas of application of the PBE boards include sandwich panels for façade elements, roof elements and partition walls.

System boundariesThe assessment is based on a “Cradle to Gate” LCA with the following additional stages: transportation to OEM (Original Equipment Manufacturer) customer sites and end of life stages. Benefits and loads beyond the system boundaries are not included in the total. The ”Cradle to Gate” assessment takes into consideration the following stages of the life cycle: from raw material extraction, (including the necessary upstream processes, auxiliaries, transports and energy supply), the manufacturing and transportation to OEM customer site, as well as the transportation to and the end of life itself. The end of life is based on landfill scenario.

ScopeStandards: the environmental data reported in this Environmental Fact Sheet are based on calculation rules according to EN 15804 (see annex).The Life Cycle Assessment (LCA) follows ISO 14040:2006 and ISO 14044:2006.

Data and tools The model used for the calculation of the LCA results is based on a verified EPD model according to EN 15804. The background LCA datasets were updated in 2012. GaBi 6 software and data were used for modelling and calculation of results. www.gabi-software.com

Verification The results and the consistency with the above mentioned standards have been checked through an extensive internal review applying PE INTERNATIONAL’s quality standards. The original underlying EPD for rock mineral wool was verified by IBU in 2013. The current LCA calculation has been conducted by PE INTERNATIONAL AG according to the PCR, Part B: requirements on the EPD for Mineral insulating materials (“Anforderungen an die EPD für Mineralische Dämmstoffe”), version 1.1 Institut Bauen und Umwelt e.V., www.bau-umwelt.com 10/2012

Global Warming Potential (GPW): impact of greenhouse gases such as carbon dioxide (CO2) or methane.

Ozone Depletion Potential (ODP): relative impact that the product can cause to the stratospheric ozone layer.

Acidification Potential (AP): the acidification of soils and waters predominantly occurs through the transformation of air pollutants into acids

Eutrophication Potential (EP): impact of nitrification by nitrogen and phosphorus to aquatic and terrestrial ecosystems, for example through algal blooms, disturbing the balance between species.

Photochemical Ozone Creation Potential (POCP): also known as summer smog, the impact from oxidizing of volatile compounds in the presence of nitrogen oxides (NOx) which frees ozone in the lower atmosphere

Abiotic Depletion Potential element (ADP- e): impact from depletion of resources excluding fossil fuel resources (such as oil or natural gas) expressed in equivalent antimony so to take into account scarcity of resources.

Non-renewable Primary Energy: non-renewable energy resources required to manufacture the product. Sources of non-renewable energy are fossil fuels and uranium.

Renewable Primary Energy: renewable energy resources required to manufacture the product. Sources of renewable energy are biomass, wind, solar or hydraulic sources for example.

Net fresh water: input of net fresh water consumed in the life cycle stages (“blue water consumption” equals evaporated water).
