Kalzip Standing Seam Roof and Wall System

Name: Kalzip Standing Seam Roof and Wall System
Brand: Kalzip

Complete insulated standing-seam aluminium roof and wall build-up. Its declared unit includes 200 mm of rock wool, so its figure covers an entire assembly rather than a cladding sheet, and it must not be compared with panel-only declarations.

Recorded Carbon Result

24.5kgCO₂e/m²

A1–A3 GWP-total per 1 m² of complete standing seam roof/wall SYSTEM: 1 mm PVDF-coated aluminium sheet plus 200 mm rock wool, 1.75 E-180 clips, vapour barrier and 3.5 fasteners (13.77 kg unpacked), as declared in EPD-KAL-20230027-IBC1-EN. SCOPE: WHOLE BUILD-UP including 200 mm rock wool insulation, clips, vapour barrier and fasteners. NOT comparable with the Kalzip FC Facade figure (16.2) or with any bare panel — most of the difference is insulation, not aluminium. Module D (-5.35) is excluded from this figure.

* A4/A5 are EPD scenarios, not project-specific results. Module nomenclature follows BS EN 15978 / EN 15804. Declared values are suitable as inputs to a whole life carbon assessment under the RICS Professional Standard (2nd edition); this panel is not an assessment.
