WISA® Form Spruce
Lightweight coated spruce plywood developed for horizontal concrete formwork. A full spruce panel bonded with weather-resistant glue and faced with a phenolic film, making it easier to handle on site and suitable for repeated slab casting and other multipurpose panel uses.

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.

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.
Sourced Product Claims

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
