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

30 years · basis not recorded

≈2 installations 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.
