History

YearDetail
1880 Imerys was founded when the Rothschild family combined their metals and mining interests into a company called Peñarroya.
1974 Peñarroya branched out, acquiring a French clay roof tile manufacturer and an American steel and metals processor, and established a holding company called Imetal to manage the businesses.
2005 Imerys acquired Lafarge Réfractaires Monolithiques, which enabled Imerys to expand its portfolio in monolithic refractories.
2015 Imerys acquired S&B, a company specialised in bentonite, continuous casting fluxes for steel, wollastonite, and perlite-based solutions.
2025 Imerys partnered with ENGIE and signed a 10-year Corporate Power Purchase Agreement (CPPA) for the annual generation of 200 GWh of renewable electricity in Spain.
