Gypsum Fibre Board
A drylining board made from recycled gypsum (largely FGD and recycled plasterboard) reinforced through its full thickness with recycled paper fibre — no paper liners, so it takes screws and impacts a standard plasterboard cannot, and one board does the job of plasterboard-plus-ply in many partitions. The paper content makes it mildly carbon-negative at the factory gate (−0.46 kgCO2e/m²); the declaration is equally clear that landfilling releases +3.44 back as the paper decomposes, so the end-of-life route decides whether the store holds.
Carbon and evidence
Product Evidence
Evidence currently held for the fermacell product record.
Recorded Carbon Result
A1–A3 GWP-total per m² of 12.5 mm board: 3.12 fossil against −3.58 biogenic held in the recycled paper fibre. The store is conditional — the same declaration puts +3.44 at C4 if the board is landfilled and the paper decomposes, so cradle-to-grave is positive unless the board is recycled.
Indicator: GWP-total
A1–A3 covers raw-material supply, transport to manufacture and manufacturing. It is product-stage information, not a whole-life result.

Covers fermacell gypsum fibre boards produced by James Hardie Europe. The declared 1 m² is 12.5 mm thick — fixed by the EPD’s own note that multiplying results by 80 represents 1 m³ at 1,180 kg/m³. Other thicknesses scale by mass.
