Carbon and evidence
Product Evidence
Evidence currently held for the Axter product record.
Recorded Carbon Result
A1–A3 GWP-total per m² of manufactured hot melt system (13.4077 kg/m²), per EPD Hub HUB-3554. A monolithic structural system, not a single membrane sheet — the declared unit is many times heavier than a single-ply membrane and the figure reads accordingly.
Indicator: GWP-total
A1–A3 covers raw-material supply, transport to manufacture and manufacturing. It is product-stage information, not a whole-life result.
