Environmental Product Declaration

EPD recorded

Coverage: Product family
Declared unit: 1 m³
Programme: EPD International AB — The International EPD System
Registration: EPD-IES-0005046:005 (S-P-05046)
Standard: EN 15804+A2
Valid until: 2029-12-19
Verification: Third-party verified

Declared per 1 m³ (density 460 kg/m³); for a per-m² figure multiply by board thickness in metres. GWP-total A1–A3 is negative because EN 15804+A2 counts the biogenic carbon stored in the timber. Phenolic film-faced (coated) spruce; EPD covers the coated WISA spruce product group.

* EPD transport and installation scenario, not this project's. Not declared: use. Module D shows potential impacts or benefits from reuse, recovery or recycling after the product's assessed life. It is reported separately and never added to A-C. Do not compare bar lengths between materials. Each chart may use a different scale and declared unit.

* A4/A5 are EPD scenarios, not project-specific results. Module D is outside the A–C system boundary and is not added to A–C. Module nomenclature follows BS EN 15978 / EN 15804. Declared values are suitable as inputs to a whole life carbon assessment under the RICS Professional Standard (2nd edition); this panel is not an assessment.

* Includes the EPD’s A4/A5 scenario assumptions, not project-specific transport or installation. This is the aggregation the proposed Part Z applies upfront limits to. The A1–A3 figure includes declared biogenic storage of -721 kgCO₂e; Part Z aggregates upfront carbon excluding sequestered carbon, which is the assessor's adjustment to make.

Service Life — the B4 Replacement Input

100 years · EPD reference service life

The declaration states 100 years as a minimum rather than an expected figure, for a board installed properly with low or moderate moisture exposure. This is a formwork panel, whose working life on site is set by reuse cycles, not by the board.

≈1 installation over a 60-year building study period.

B4 (replacement) follows the building, not the product: an assessor multiplies replacement cycles by project quantities. This record supplies the service life and does not compute B4.

Comparison Status

The record contains the basic metadata required for a controlled comparison. Products must still perform the same function and use compatible units, PCRs and lifecycle scope.

Evidence Gaps

•1 sustainability claim is withheld because exact public evidence is not mapped.

Design & Specification Notes

Qualitative notes for early design discussion. Not product-specific EPD evidence, and not a basis for numerical comparison.

Lightweight coated spruce plywood developed for horizontal concrete formwork.

Typical Uses

•Interior wall cladding
•Warm feature panels
•Lobby accents

Specification Actions

•Confirm FSC or PEFC certification for all timber products.
•Request chain-of-custody documentation from supplier.
•Confirm the current EPD covers the selected product, finish and manufacturing route.
