STEICOinstall Wood Fibre Board
A wood fibre insulation board for service voids, internal linings and between-stud applications, made from softwood fibre in a dry process. Vapour-open and dense enough to give useful decrement delay, so it works for summer overheating as well as winter heat loss.

Carbon and evidence
Product Evidence
Evidence currently held for the STEICO product record.
Recorded Carbon Result
A1–A3 GWP-total per m³. Negative because 244 kgCO2e of biogenic carbon is held in the wood fibre. The EPD declares C3 = +239 kgCO2e when the board is processed at end of life, so the store is a deferral, not a permanent removal. Declared per m³ — divide by thickness for an m² figure.
Indicator: GWP-total
A1–A3 covers raw-material supply, transport to manufacture and manufacturing. It is product-stage information, not a whole-life result.
