Marley low‑carbon roof tiles: carbon capture and specification notes for engineers
Reviewed by Tom Sullivan
First reported on The Construction Index
30 Second Briefing
Marley has launched Edgemere 2.0 concrete interlocking roof tiles using Heidelberg Materials’ evoZero cement, which relies on carbon captured and “banked” from Heidelberg’s Brevik plant in Norway, currently sequestering about 400,000 tonnes of CO₂ per year. The tiles carry a low Global Warming Potential, Green Guide A+ rating and BES 6001 Excellent certification, targeting specifiers seeking verifiable low‑carbon roofing materials. Heidelberg is also constructing a carbon capture plant at its Padeswood cement works in north Wales, designed to capture about 95% of emissions, or roughly 800,000 tonnes of CO₂ annually, from 2029.
Technical Brief
- Carbon capture at Brevik currently removes about 400,000 tonnes of CO₂ annually from cement production streams.
- Padeswood’s planned capture rate of ~95% equates to roughly 800,000 tonnes of CO₂ abated each year.
Our Take
Marley’s low‑carbon tiles tie directly into Heidelberg Materials’ evoZero cement work at Brevik and the planned 95% capture facility at Padeswood, signalling a push to turn carbon‑captured binders into branded downstream building products rather than just bulk cement sales.
In our Materials coverage, Heidelberg Materials appears repeatedly in relation to both autonomous quarrying and low‑carbon asphalt and concrete in the UK, so using evoZero‑type inputs in Marley roofing would extend that decarbonisation narrative from road and rail infrastructure into the residential and commercial building envelope.
The 2029 operational date for Padeswood’s capture plant implies that any Marley product line explicitly linked to evoZero cement will have a staged rollout: early volumes are likely to depend on Brevik supply, with scale‑up in the UK contingent on Padeswood hitting its capture performance in practice.
