| Use advice for data set | Scope: This EPD applies to all declared products of the IVPUs member companies Karl Bachl GmbH & Co KG, Holcim Solution and Products EMEA BV, IKO Insulation BV, Kingspan Insulation GmbH & Co KG, Linzmeier Bauelemente GmbH, puren gmbh, Recticel NV/SA, Soprema GmbH, Steinbacher Dmmstoff GmbH, Unilin Insulation bv. The IVPU represents more than 90% of the companies within the German polyurethane insulation products market. This EPD is based on weighted averages which have been determined on the basis of the single values originating from the factories of the mentioned manufacturing companies (see section 3.1). System boundary: The type of EPD according to EN15804 is cradle to gate with options, modules C1-C4, and module D. Life cycle assessment considers the following steps of the life cycle: Production and supply of raw materials (A1) Transporting raw materials (A2) Production including packaging (A3) Transport to construction site (A4) Installation in buildings (thermal treatment of packaging waste) (A5) Transport to End-of-Life (C2) Waste treatment: energy for shredders (C3) Thermal treatment (PU foam) (C3) Recycling or use potentials beyond the system's boundary (D). | ||
| Technical purpose of product or process | The scope of application of PU rigid foam insulation materials includes thermal insulation in building construction (e.g. pitched roofs, flat roofs, floors, ceilings and exterior walls (inside and outside). | ||

| General comment on data set | Factory made rigid polyurethane foam (PU) products are used for the thermal insulation of buildings. PU includes both PIR and PUR products. The products are manufactured in the form of boards without or with flexible facings. This Product Declaration covers PU insulation boards with multi-layer aluminium foil facings on both sides. | ||

| Technology description including background system | Polyurethane rigid foam insulation boards with flexible multi-layer aluminium facings are produced in a continuous process on a double belt line. In this process, the polyurethane reaction mixture pours from a mixing head onto the bottom facing where it foams up and glues – still within the line's pressure area – with the top multi-layer aluminium facing. After passing the double belt line, the foam boards are cut to the desired dimensions. Quality assurance The declared products are subject to quality controls. Quality assurance is based on surveillance and certification by independent Notified Bodies. Technical data: For determining technical data, testing methods as stated in EN 13165 are used. The gross density of PU insulation boards with multi-layer aluminium facings for building construction is approx. 31 - 32 kg/m. The nominal thermal conductivity is 0.022 W/(m.K), the thermal conductivity design value which is used for calculating the thermal performance of insulation layers in buildings is 0.023 W/(m.K). In addition, the nominal value of the thermal resistance of RD = 5.45 (m.K)/W and the thickness of 22 mm of the insulation board at RD = 1 (m.K)/W can be specified. Nominal compressive stress or nominal compressive strength at 10% deformation is 100 kPa (dh) or 150 kPa (ds) acc. to DIN 4108-10. Higher compressive strength is possible. Nominal tensile strength perpendicular to the insulation board plane is 40 kPa. Higher tensile strength is possible. PU insulation boards with multi-layer aluminium facings are impermeable to water vapour and do not absorb moisture. Polyurethane rigid foam is a distinctive thermosetting material and therefore cannot be melted. Declared unit: The declared unit is 1 m of installed PU thermal insulation board with multi-layer aluminium facing (on both sides) and has the following specifications: | ||
