| Technical purpose of product or process | Product variation and calculation of averages: - The insulation board is provided in several dimensions and thicknesses. Please use the conversion table in this EPD for other sizes and densities than the declared variant. Product description: - BEWI Super EPS are boards made from expanded polystyrene (EPS). Graphite is added to the raw material, which gives it the grey color and at the same time reduces radiant heat loss, thereby decreasing thermal conductivity by approximately 20% (compared to traditional white EPS, Jackopor Flamingo). Then it's possible to meet the same energy requirements with 20% less volume, lower CO2 footprint, and less material usage. - Expanded polystyrene (EPS) is a common material used for thermal insulation of buildings, including floors, walls and roofs. It is a polymer foam, consisting of air-filled polystyrene cells. As 98% of the material is air, EPS provides good insulating properties at a low weight. Other characteristics of the material include low moisture absorption, long service life, high compressive strength and 100% recyclable. - EPS is manufactured through permeating polystyrene beads with pentane, allowing the beads to expand when exposed to steam. This addition of a so-called blowing agent adds 4% - 6% w/w. In BEWI Super EPS, graphite is added in small amounts to further improve thermal insulation properties. The expanded polystyrene (EPS) beads are then fed into a block molding machine, where steam and pressure forms large blocks of EPS. The amount of EPS going into the mold determines the density of the block, where pressure class 80 (JS80) provides a compressive stress at 80 kN/m², which is approximately 16,3 kg/m³. After molding, the remaining blowing agent, pentane, is aired out and the blocks are cut into the desired shape. - Weight per declared unit is 0,51 kg given a density of 16,3 kg/m³ with a thickness of 31 mm. |

| General comment on data set | Data quality: Specific data for the product composition are provided by the manufacturer. The data represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on EPDs according to EN 15804 and different LCA databases. The data quality of the raw materials in A1 is presented in the table below. Allocation: The allocation is made in accordance with the provisions of EN 15804+A2. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances. |
