kSIST FprEN 18159:2026 is a SIST standard that gives complementary product category rules for Type III environmental declarations (EPD) of double skin metal faced insulating sandwich panels for roofing and cladding. It is built on EN 15804 and tells EPD authors how to model the life cycle, choose scenarios and report results for panels used in building envelopes.
What does kSIST FprEN 18159:2026 specify?
kSIST FprEN 18159:2026 specifies product category rules (c-PCR) for EPDs for sandwich panels within the scope of prEN 14509-1:2024 and prEN 14509-2:2024. The document covers panels for non-structural and structural uses in building envelopes, including panels with perforated faces and panels with core materials other than those defined in those two parts. It is intended for cradle-to-gate with options or cradle-to-grave assessment in line with EN 15804, and it excludes social and economic performance at product level.
The standard is organized around scope, references, terms, general EPD rules, life cycle assessment rules, EPD content, project report requirements, verification, and annexes. The annexes provide the practical data and scenario rules that EPD writers need when product-specific data are not available.
| Annex | What it covers |
|---|---|
| A | Reference service life (RSL) guidance |
| B | Waste |
| C | Impact categories, indicators, methods and characterization factors |
| D | End-of-life formulae |
| E | Data quality assessment schemes |
| F | Illustration of sandwich panel material flows |
| 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 reuse, recycling and loss rates |
| L | Interpolation rules |
| M | Selection of additional environmental indicators |
What are the key requirements of kSIST FprEN 18159:2026?
The main requirement is to apply EN 15804 together with the extra rules in this document when preparing an EPD for these sandwich panels. In practice, that means the EPD must describe the panel type, the life cycle modules included, the data used, the scenarios applied and the indicators reported, so that declarations for similar panels are prepared on the same basis.
Product scope, materials and declared unit
Clause 6.1 makes clear that the product category includes sandwich panels in the scope of prEN 14509-1:2024 and prEN 14509-2:2024, plus panels with perforated faces and with other core materials. Face materials and core materials have to be identified in the EPD, so a reader can see what product the declaration actually represents.
Clause 6.3.3 sets the declared unit as 1 m of a sandwich panel. That matters because the environmental results are reported per metre, so manufacturers and buyers can compare declarations for panels of different lengths on the same basis. Annex L then allows interpolation between thicknesses within one panel category when the face material, face weight, core material and core density are the same.
Life cycle stages and modelling rules
Clause 6.2 requires the EPD to cover the relevant life cycle modules. A1-A3 cover the product stage, A4-A5 the construction stage, C1-C4 the end-of-life stage, and D the benefits and loads beyond the system boundary.
For A1-A3, separate declaration of A1 and A3 is not compulsory, but the document distinguishes upstream material production from panel manufacturing and packaging, and it requires transport between those steps to be included where it occurs. For A4 and A5, the document follows EN 15804 and adds default data in Annexes G and H. For C1-C4, the document follows EN 15804 and adds default data in Annexes I, J and K.
End-of-life and module D
Clause 6.2.8 and Annex K set out how reuse, recycling, recovery and disposal are treated at end of life. Waste processing up to the end-of-waste state is reported in the module where it occurs, and the document gives default rates when a more specific scenario is not available.
Module D includes benefits and loads beyond the system boundary. For metal faces, it includes the conversion of metal scrap into recycled cast metal and the reuse of products, including transport, storage and any finishing needed before substitution. In practice, this is the part that captures credits from recycling or reuse beyond the product system.
Default data and scenarios
Annex G gives default transport data for module A4, including a load-based diesel calculation for transport from factory gate to site. Annex H gives default installation data for module A5, including a default diesel use per metre and a 2 % loss rate. Annex I gives default deconstruction data for module C1, and Annex J gives default transport data for module C2.
These defaults matter when project-specific data are not known. They make the EPD usable even when a company cannot trace every transport leg or installation detail, but they also mean the declared result depends on the scenario assumptions chosen from the annexes.
Indicators, reporting and verification
Section 7 defines what the EPD has to report: general information, LCA-based environmental indicators, technical scenario information, and additional information on dangerous substances. Clause 5.4.2 and Annex M guide the selection of additional environmental indicators for metal-faced panels, and the document advises against declaring freshwater ecotoxicity, human cancer effects and human non-cancer effects for faces unless they are mandatory in the intended market. It also advises not to report the particulate matter indicator when source data reliability is in doubt.
Sections 8 and 9 require a project report, data availability for verification, and verification and validity of the EPD. In practice, this means the EPD must be traceable back to the underlying calculations and data so it can be checked by a verifier.
What terms does kSIST FprEN 18159:2026 define?
- Environmental product declaration (EPD) - A standardized declaration that reports the environmental performance of a product using LCA-based information.
- Product category rules (PCR) - Rules that define how EPDs are prepared for one product group so that they are comparable.
- Complementary product category rules (c-PCR) - Extra product-specific rules that refine EN 15804 for double skin metal faced insulating sandwich panels.
- Life cycle assessment (LCA) - The method used to compile and assess inputs, outputs and impacts across the product life cycle.
- Life cycle inventory analysis (LCI) - The collection and calculation stage for energy, material and emission flows.
- Life cycle impact assessment (LCIA) - The step that turns inventory flows into environmental impact indicators.
- Reference service life (RSL) - The service life used for scenario calculations; Annex A sets guidance that sandwich panels have an RSL of at least 50 years.
- Core - The insulating layer bonded between the two metal faces of the panel.
- Face - The thin metal sheet bonded to the core on either side.
Who uses kSIST FprEN 18159:2026?
This standard is used by sandwich panel manufacturers, EPD authors, LCA practitioners, environmental managers and verification bodies. It helps them prepare declarations for roofing, cladding, wall and ceiling applications in building envelopes.
Buyers, specifiers, architects and quality managers use it to understand what an EPD for these panels covers and how the result was built. It is also relevant in construction-product supply chains where environmental reporting, procurement or certification depends on a panel EPD that follows EN 15804.
Which standards are used with kSIST FprEN 18159:2026?

What does the kSIST FprEN 18159:2026 document contain?
The document contains the full PCR structure for EPDs of these sandwich panels, including scope, definitions, life cycle rules, reporting rules and verification requirements. It also contains a table that assigns processes to modules A1 and A3, and several annexes with practical calculation inputs and scenario defaults.
It includes an illustration of material flows for sandwich panels, default transport and installation data, default deconstruction data, and default end-of-life rates. Annex G and Annex J include a load-based transport formula and an example calculation, while Annex H and Annex I provide default consumption values for installation and deconstruction.
Annex K gives default reuse, recycling, recovery and landfill values, Annex L gives interpolation rules for separate EPDs, and Annex M explains why some additional impact indicators are usually excluded for metal-faced panels. Together, these annexes are what EPD practitioners use to turn the general PCR into an actual declaration.

The additional impact indicator designated in EN 15804:2012+A2:2021 as ‘Potential incidence of disease
due to Particulate Matter emissions (PM)’ should not be declared when doubt has been identified about
the reliability of source data.
