What are the stage A1-A3 carbon factors for mineral wool insulation and standard 12.5mm gypsum board?
| Checked | Without skill | With skill |
|---|---|---|
| Specifies mineral wool insulation stage A1-A3 carbon as 45 kgCO2e per cubic meter. | Missed | Passed |
| Specifies 12.5mm gypsum board stage A1-A3 carbon as 3.2 kgCO2e per square meter. | Missed | Passed |
