P RODUCT D ESCRIPTION P RODUCT NAME This EPD contains the environmental impact of the ARGEX lightweight expanded clay aggregate reference product AR 8/16 – 340 GEO . P RODUCT DESCRIPTION Lightweight expanded clay aggregate ARGEX is a granular ceramic material made from clay, and the product is distributed in bulk or bags. I NSTALLATION This EPD includes the impacts of all materials and processes necessary for installing/mounting the product accordingly. A single scenario was defined for this EPD based on the following options: i. blowing followed by a vibrating plate for levelling and compaction, ii. blowing followed by a manual levelling. I MAGES OF THE PRODUCT AND ITS INSTALLATION I NTENDED USE This product is used for thermal applications of roofs, floors and foundations, etc.* * For the full list of thermal insulation applications, please refer to EN 14063-1. For technical data: see the DoP (following EN 14063-1), and technical sheets (https://www.argex.eu). F UNCTIONAL UNIT / R EFERENCE FLOW The functional unit is the thermal insulation of 1m² for buildings (roofs, floors and foundations, etc.), using AR 8/16 – 340 GEO, applied with a thickness of 11.4 cm that gives a thermal resistance (R- value) of 1 (m²∙K/W) , with a life span of 100 years". The most important part of the product is sold in bulk. The packaging is included for the 1.60% of the final product sold in big bags. The weight per reference flow is 38.76 kg. The loose bulk density of the product is 340 kg/m 3 . The environmental assessment is conducted for AR 8/16 GEO with 11.4 cm thickness as reference product, providing a thermal resistance equals to 1 m 2 K/W. A range of thickness is applicable for this product (0.1 – 2 m). To obtain the impacts related to the different thicknesses, conversion factor should be multiplied by the results presented in this B-EPD. Conversion factor is calculated dividing the actual weight by the reference flow weight (38.76 kg). Table below includes conversion factors for different thicknesses. Functional Units R = 1 m 2 K/W thickness = 11.4 cm R = 1.75 m 2 K/W thickness = 20 cm Product Reference Conversion factor Weight (kg) Conversion factor Weight (kg) AR 8/16 1 38.76 1.75 68 Figure 1: Lightweight expanded clay aggregate material Figure 2: Examples of lightweight expanded clay aggregate in thermal insulation applications Figure 3: Blowing with vibrating plate levelling-compaction installation Figure 4: Blowing with manual levelling installation Conversion factor 2.63 R = 2.63 m 2 K/W thickness = 30 cm Weight (kg) 102 Conversion factor 3.51 R = 3.51m 2 K/W thickness = 40 cm Weight (kg) 136 2
