Sandtoft Double Pantile & Double Roman
Large-format profiled concrete tiles — Double Roman’s twin-roll profile and the Double Pantile, both laid at about ten to the square metre. At roughly 9.1 kgCO₂e/m² this is the lowest-carbon roof covering per square metre in the Wienerberger range, on their own published conversions.
Carbon and evidence
Product Evidence
Evidence currently held for the Wienerberger product record.
Recorded Carbon Result
A1–A3 GWP-total per tonne, as declared. GWP-fossil for the same stage is 207 kgCO2e/t — the gap is timber-pallet biogenic carbon booked in A3 and released in A5, a packaging artefact rather than a property of the tile, and it is the figure Wienerberger themselves publish. Both are stored. On the manufacturer's own conversion this tile is about 9.1 kgCO₂e per m² of roof (GWP-fossil basis, manufacturer-published rather than part of the verified declaration).
