STEICOuniversal dry
A rigid dry-process wood fibre board — combined sarking, sheathing and render-carrier board — the denser sibling for direct render systems. Dry-process boards are denser and stiffer than the flexible batts, bonded with a small PMDI resin content rather than heat-felted, and they weatherproof a timber frame during construction while adding decrement delay the lightweight alternatives cannot. The declaration is per cubic metre and negative at A1–A3 only because the stored biogenic carbon outweighs production emissions; C3 hands 357 kgCO2e back if the board is incinerated at end of life.
Carbon and evidence
Product Evidence
Evidence currently held for the STEICO product record.
Recorded Carbon Result
A1–A3 GWP-total per m³ of board (210 kg). Negative because 363 kgCO2e of biogenic carbon is held in the fibre against 161 of fossil emissions. The store is not permanent: C3 declares +357 kgCO2e when the board is incinerated at end of life, so cradle-to-grave is close to neutral.
Indicator: GWP-total
A1–A3 covers raw-material supply, transport to manufacture and manufacturing. It is product-stage information, not a whole-life result.

Design & Specification Notes
Qualitative notes for early design discussion. Not product-specific EPD evidence, and not a basis for numerical comparison.
A rigid dry-process wood fibre board — combined sarking, sheathing and render-carrier board — the denser sibling for direct render systems.
Typical Uses
- •Thermal envelope
- •Roof/wall cavities
- •Airtightness layers
Key Performance
Good thermal resistance with reduced heat loss.
Typical Service-Life Estimate
60 yearsGeneric estimate for early design discussion; confirm with the manufacturer.
Specification Actions
- •Compare embodied carbon of insulation options (natural vs synthetic).
- •Request blowing agent GWP values for foam insulation.
- •Confirm the current EPD covers the selected product, finish and manufacturing route.
