| Use advice for data set | Scope: This EPD applies to all declared products of the IVPU's member companies Karl Bachl GmbH & Co KG, Paul Bauder GmbH & Co KG, IKO Insulation BV, Kingspan Insulation GmbH & Co KG, Linzmeier Bauelemente GmbH, puren gmbh, Recticel Dämmsysteme GmbH, Remmers Baustofftechnik GmbH, Steinbacher Dämmstoff-GmbH, Unilin Insulation bv. The IVPU represents more than 90% of the companies within the German polyurethane insulating materials 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 aforementioned manufacturing companies (see section 3.1). System boundary: Type of EPD: cradle to gate - with options The 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 (recycling or thermal treatment of cutting leftovers and packaging waste) (A5) · transport to End of Life (C2) · waste treatment: energy for shredders (C3) · thermal treatment (PU foam) or recycling (aluminium) (C4) · 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 | Polyurethane rigid foam (PU) is a closed-cell foam and factory-made thermal insulating material, which is used in the form of insulation boards with or without facings for insulating buildings, as well as for insulation of building equipment and industrial installations. The polyurethane insulating material (PU) product family comprises the product variants polyurethane (PUR) and polyisocyanurate (PIR) - see /EN 13165/. PU insulating materials are produced as block foam and insulation boards with flexible facings. This Product Declaration covers PU insulation boards with mineral fleece facings on both sides. |

| Technology description including background system | Polyurethane rigid foam insulation boards with flexible mineral fleece 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 mineral fleece facing, where it foams up and glues – still within the line’s pressure area – with the top mineral fleece facing. After passing the double belt line, the foam boards are cut to the desired dimensions. Quality assurance The declared products bear the quality mark of “Überwachungsgemeinschaft Polyurethan-Hartschaum”. Quality assurance is based on surveillance and certification by independent Notified Bodies. Technical data: For determining technical data, testing methods as stated in / DIN EN 13165 / are used. The gross density of PU insulation boards with mineral fleece facings for building construction is approx. 31 kg/m³. Depending on their thickness, the boards are manufactured with thermal conductivity levels WLS 026 up to WLS 029. These levels are equivalent to thermal conductivity design values from 0.026 W/(m.K) up to 0.029 W/(m.K). Capillary-actively modified insulation boards have design values of 0.031 W/(m.K). 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 is 40 kPa. Higher tensile strength is possible. The water vapour diffusion resistance factor µ of polyurethane rigid foam is between 40 and 200 acc. to DIN 4108-4. Maximum moisture absorption of polyurethane rigid foam at diffusion and condensation is at approx. 6 % by volume. Water absorption at total immersion of a 60 mm thick PU insulation board with mineral fleece facings was measured at 1.3 % by volume after 28 days. Moisture absorption after freezing and thawing was between 2 % and 7 % by volume (measured at insulating material without facings). Polyurethane rigid foam is a distinctive thermosetting material and therefore cannot be melted. Declared unit: The declared unit is 1 m² of installed PU thermal insulation board with mineral fleece facing (on both sides) and has the following specifications: |
