Low Carbon Single Skin Precast Panel
An architectural precast cladding panel cast with a deliberately low-carbon mix — white cement cut with supplementary cementitious materials to the limits BS 8500:2023 allows. On Techrete’s own declarations it comes in at 48.5 kgCO2e/m² against 54.8 for their standard grey-cement panel on the same 150 mm basis, and it carries a small declared carbonation credit in use. Precast is bought as a manufacturer’s engineered panel, not a poured mix, which is why the EPD is per m² of panel rather than per m³ of concrete.
Carbon and evidence
Product Evidence
Evidence currently held for the Techrete product record.
Recorded Carbon Result
A1–A3 GWP-total per m² of 150 mm architectural panel (377.6 kg). Essentially all fossil (48.4) — precast holds no meaningful biogenic store. Techrete’s own grey-cement panel declares 54.8 on the same basis; B1 carbonation gives back a further 0.55 in use.
Indicator: GWP-total
A1–A3 covers raw-material supply, transport to manufacture and manufacturing. It is product-stage information, not a whole-life result.
