Sandtoft Calderdale Edge & TLE
Large-format interlocking concrete tiles — the flat-profile Calderdale Edge and the through-coloured TLE, laid at around ten to the square metre. Fewer, larger tiles is the single biggest lever on a tiled roof’s carbon: about 9.5 kgCO₂e/m² against roughly 20 for the small-format plain tile off the same site.

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 9.5 kgCO₂e per m² of roof (GWP-fossil basis, manufacturer-published rather than part of the verified declaration).
