EN 18159:2026 is a CEN document for Environmental Product Declarations (EPD) of double skin metal faced insulating sandwich panels for roofing and cladding. It is complementary to EN 15804 and tells manufacturers, LCA practitioners and verifiers how to describe these panels, which life-cycle modules to report, and what additional technical information to include for building-envelope applications.
What does EN 18159:2026 specify?
EN 18159:2026 specifies product category rules (c-PCR) for Type III environmental declarations of sandwich panels covered by the prEN 14509 family, including panels with perforated faces and panels with core materials other than those defined in that family. It is written for industrially manufactured panels used in roofs, outer walls, wall cladding, internal walls, partition walls and suspended ceilings inside the building envelope.
The document is organized into clauses 1 to 9, followed by Annexes A to M. Clause 1 sets the scope, Clause 2 lists the normative references, and later clauses cover terms, general aspects, life-cycle assessment (LCA) rules, EPD content, the project report, and verification.
| Annex | What it covers |
|---|---|
| A | Requirements and guidance on the reference service life (RSL) |
| B | Waste |
| C | Impact categories, indicators, methodologies and characterization factors |
| D | End-of-life formulae |
| E | Data quality assessment schemes for generic and specific data |
| F | Illustration of material flows of sandwich panels |
| G | Default transport data for module A4 |
| H | Default installation data for module A5 |
| I | Default deconstruction data for module C1 |
| J | Default transport data for module C2 |
| K | Default rates for reuse, recycling and losses |
| L | Interpolation rules |
| M | Selection of additional environmental indicators |
What are the key requirements of EN 18159:2026?
EN 18159:2026 sets the rules for how an EPD for these sandwich panels is built, what life-cycle stages are included, and how end-of-life and additional environmental information are handled. In practice, it tells you what product data you need, what can be estimated with defaults, and what must be stated clearly in the declaration.
Scope and product identification
Clause 6.1 requires the product category to include all sandwich panels within the prEN 14509 scope for structural and non-structural use, plus panels with perforated faces and panels with other core materials. Face materials and core materials have to be specified in the EPD. That matters because the environmental results depend on the exact metal face and insulation core.
Life-cycle stages to declare
Clause 6.2 requires reporting across the relevant EN 15804 modules, including product stage, construction process stage, use stage, end-of-life, and module D. For faces, transport impacts shall be included where relevant, and actual distances and transport modes shall be used when known. This means the EPD should follow the real supply chain and installation route, not just generic assumptions.
Clause 6.2.2 says a separate declaration of A1-A3 is not compulsory, but all transport steps between processes within and between A1 and A3 shall be included and reported where they occur. Annex F shows the material flow logic used for the panels. That helps avoid double counting or missing factory and upstream transport steps.
Construction, use and end-of-life rules
Clause 6.2.3 refers to A4 and A5, with default data in Annexes G and H when site-specific information is not available. Annex H includes installation losses and diesel use, so a project team can build a practical site scenario even when contractor data are incomplete.
Clause 6.2.6 and 6.2.8 cover C1 to C4 and the handling of waste up to end-of-waste state. Annex I gives default deconstruction data, Annex J gives transport data for C2, and Annex K gives default reuse, recycling, recovery and disposal rates. In practice, the user needs to choose a realistic end-of-life route, because reuse and recycling are treated differently from disposal.
Clause 6.2.7 and Table 2 define module D for benefits and loads beyond the system boundary. For metal faces, module D includes the conversion of scrap into recycled cast metal and the reuse of products, with transport and related energy and water use where relevant. This is the place where credits for recovered material are shown.
Calculation rules and declared unit
Clause 6.3.3 sets the declared unit as 1 m of a sandwich panel. Annex L allows interpolation between thicknesses, but only within the same panel category, meaning the same face material, facings weight, core material and core density. This matters if one EPD is used for a product range rather than one exact thickness.
Clause 6.3.4 uses the reference service life (RSL) rules in Annex A. Annex A states an RSL of at least 50 years, with use according to the product description, appropriate maintenance, and consideration of location, weather and coating quality for steel faces. That informs durability assumptions in EPD scenarios and in building assessments.
EPD content and additional indicators
Clause 7 requires the EPD to declare general information, LCA-derived indicators, scenarios and technical information, and any additional information on dangerous substance release during use. Clause 7.5 covers aggregation of information modules, so results can be presented in the format required by the EPD programme.
Clause 5.4.2 and Annex M limit some additional environmental indicators for faces. The indicators for freshwater ecotoxicity, human cancer effects and human non-cancer effects should not be declared unless mandatory in the intended market, and the particulate matter indicator should not be declared when source-data reliability is doubtful. In practice, this keeps the declaration focused on indicators that are better supported by the available data.
What terms does EN 18159:2026 define?
- EPD - Environmental product declaration, the Type III declaration format used for reporting product environmental information.
- PCR - Product category rules, the rules that define how a product group is assessed and declared.
- c-PCR - Complementary product category rules, the additional rules that work with EN 15804 for this product group.
- LCA - Life cycle assessment, the method used to calculate environmental impacts across life-cycle stages.
- LCI - Life cycle inventory analysis, the collection and calculation of input and output flows.
- LCIA - Life cycle impact assessment, the step that turns inventory data into environmental impact indicators.
- RSL - Reference service life, the assumed service life used in the EPD scenario.
- CF - Characterization factor, the factor used in impact calculations.
- ND - Not declared, used where an indicator is not reported.
Who uses EN 18159:2026?
EN 18159:2026 is used by manufacturers of double skin metal faced insulating sandwich panels, LCA consultants, EPD programme operators, and independent verifiers. It is also used by quality, sustainability and procurement teams that need comparable EPDs for roofing, cladding and building-envelope panels.
In practice, these users apply it when preparing an EPD, selecting the right system boundary, choosing default data for transport, installation or deconstruction, and documenting the panel build-up. Architects, specifiers and buyers use the resulting EPD to compare product variants and to feed building-level environmental assessments.
Which standards are used with EN 18159:2026?
- EN 15804:2012+A2:2019 - the core rules for EPDs of construction products; EN 18159 is complementary to it.
- EN 16783:2017 - provides the wider EPD framework for thermal insulation products and is referenced for general information on core materials.
- prEN 14509-1 - defines self-supporting applications for factory-made double skin metal faced insulating sandwich panels.
- prEN 14509-2 - defines structural applications for these panels.
- EN ISO 9229:2020 - supplies the thermal-insulation vocabulary used in the document.
What does the EN 18159:2026 document contain?
EN 18159:2026 contains the rules for LCA calculation, the required EPD content, and the verification and validity framework for the declaration. It also contains a project-report section that asks for the LCA-related elements and the documentation needed for verification.
The annexes provide the practical tools behind the rules. These include the RSL guidance, impact-category and characterization-factor data, end-of-life formulae, data-quality schemes, a material-flow illustration, and default data for transport, installation and deconstruction.
It also includes default rates for reuse, recycling and losses, plus interpolation rules for declaring panel thickness ranges. Annex M explains why some additional environmental indicators are treated cautiously for this product group, especially for metal-faced panels.
