Denmark: Rockwool recorded full-year sales of €3.88bn in 2025, up by 1% year-on-year from €3.86bn in 2024. Nonetheless, group earnings before interest, taxation, depreciation and amortisation (EBITDA) fell by 8% year-on-year from €940m to €864m in 2024. The producer partly attributed this to two plant closures, a ‘production incident’ at a plant in Switzerland and ‘lower performance’ in its former Russian business, which the Russian government forcibly transferred to Rozvitok Stroitelnykh Aktivov in January 2026.
Rockwool reduced its absolute Scope 1 and Scope 2 CO₂ emissions by 20% between 2019 and 2025, against a 2034 goal of 38%. Its insulation products sold in 2025 will, over their lifetime, save more than 100 times the energy used to produce them, according to the producer.
Looking ahead to 2026, Rockwool forecast 2 – 4% sales growth in local currencies. Capacity expansions are underway in India, Romania and the US, with a new plant project in France scheduled to recommence later in the year. ‘Several large plants’ are also undergoing conversion to electric melting, bringing total investments for the year to €650m, excluding acquisitions.
