Foam Insulation, Expanded Polystyrene (EPS) (density 20 kg/m³), EUMEPS (RER)
Use advice for data set Scope: The companies contributing to the data collection produce one third of the expanded polystyrene foam boards sold by the members of the EUMEPS association in Europe. The data have been provided by 21 factories out of 20 companies for the year 2015. The applicability of the document is restricted to EPS boards produced by manufacturing plants of EPS converters who are members of their national EPS association, which themselves are members of EUMEPS. System boundary: Type of the EPD: cradle to gate - with options. The analysis of the product life cycle includes production of the basic materials, transport of the basic materials, manufacture of the product and the packaging materials and is declared in module A1-A3. Transport of the product is declared in module A4, and disposal of the packaging materials in module A5. Gained energy from packaging incineration is declared in module D, beyond the system boundary. The use stage is not taken into account in the LCA calculations. The positive impact on environment due to energy saving depends on the application system in the building. This needs to be considered on next level by the evaluation of buildings. The end-of-life scenarios include the transport to end-of-life stage (C2) EoL-scenario 1: 100% incineration: The effort and emissions of an incineration process is declared in module C4. Resulting energy is declared in module D EoL-scenario 2: 100% Material recycling: The effort of material treatment is considered in C3. Resulting benefits on avoided primary material is declared in module D.

General comment on data set This EPD describes Expanded Polystyrene foam (EPS). The closed cell structure is filled with air (98% air; only 2% polystyrene) and results in a light weight, tough, strong and rigid thermoplastic insulation foam. The products are mainly used for thermal and acoustical insulation of buildings. The foam is available in various dimensions and shapes. Boards can be supplied with different edge treatments such as butt edge, ship lap, tongue and groove. Density range is from about 18 to 22 kg/m³ corresponding to a compressive strength value of about 100 kPa. This EPD is applicable to homogeneous EPS products without material combinations or facings. Most important properties are the thermal conductivity and compressive strength. The applicability of the document is restricted to EPS boards produced by manufacturing plants of EPS converters who are members of their national EPS association, which themselves are members of EUMEPS. The data have been provided by a representative mix of 21 converters from amongst the EUMEPS membership from all parts of Europe, based upon production during 2015. For the placing on the market of the product in the EU/EFTA (with the exception of Switzerland) Regulation (EU) No. 305/2011 (CPR) applies. The product needs a Declaration of Performance taking into consideration /EN 13163:2012+A1:2015 Thermal insulation products for buildings , Factory made expanded polystyrene (EPS) products — Specification/ and the CE-marking. These products are additionally approved for use in specific applications under mandatory or voluntary agreement or certification schemes at the national level. These products are controlled and certified by Notified Bodies. A large number of the manufacturing plants are certified according to /ISO 9001/ and/or /ISO 14001/.

Technology description including background system The conversion process of EPS beads to foamed insulation consists of the following manufacturing stages: pre-foaming, conditioning and finally block moulding. During the pre-foaming and moulding stages heating by steam causes the foaming of the beads due to the pentane blowing agent. The final shape is achieved by hot wire cutting of the block to give the desired board dimensions. Finally, the board edges are trimmed by cutting or grinding to obtain the desired edge detail. Typically cut offs are 100% recycled in line. Technical data: Performance data of the product in accordance with the Declaration of Performance with respect to its Essential Characteristics according to EN 13163:2012+A1:2015. Additional data: Declared unit: The declared unit is 1 m³ expanded polystyrene rigid foam. In addition, the results for the functional unit of a volume per square metre that leads to an R-value of 1 are considered. The conversion factors are listed in the table below.
