Evidence Base

Category estimate

No product evidence is attached to this generic material, so nothing on this card is numerical. The guidance below is qualitative — an AI-assisted category profile — for early design discussion, not for figures.

Next step: request a current product EPD or manufacturer carbon declaration, or swap in a branded product that holds one.

What's missing (3)

•No current product EPD is recorded.
•No quantified carbon result is recorded.
•No product-specific circularity or material-health claims are recorded.

Service Life — the B4 Replacement Input

60 years · basis not recorded

≈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.

Design & Specification Notes

Bio-based insulation boards from agricultural straw for walls and roofs, supporting moisture-buffering and low-embodied-carbon envelope design.

Typical Uses

•Thermal envelope
•Roof/wall cavities
•Airtightness layers

Key Performance

Good thermal resistance with reduced heat loss.

Watch For

•
Moisture accumulation in poorly detailed envelopes
Use vapour-open build-up design with robust airtightness and rain control layers.
•
Site damage during wet construction periods
Protect panels with dry storage, phased installation, and immediate weatherproofing.

Specification Actions

•Provide product declaration covering bio-based content, binder additives, and EPD or equivalent carbon assessment.
•Verify moisture, fire, and settlement performance with tested wall/roof build-ups and airtightness strategy.
•Specify dry, demountable build-ups so panels can be removed intact and reused or composted where permitted.

Indicative Health & Indoor Air

low Risk

•dust
•fire-retardants

Natural fibre product with generally low in-use emissions; verify fire treatment chemistry and control dust during installation.
