ROCKWOOL releases H1 2026 results

August 19, 2026

Record high second quarter revenue driven by volume increases.

“We achieved record high Q2 sales, driven by volume increases. Sales improved strongly in most regions, with South and Eastern Europe, Asia, and the United States performing especially well. Profitability was good in both the quarter and for the half-year.

With the measures now in place to mitigate energy and transportation cost increases, we expect full year profitability to remain within expectation. Investments in capacity expansion and electrification as well as automation and other digital initiatives will remain a priority.

Energy price increases are driving greater focus on energy efficiency in the built environment, thus creating greater demand for insulation. More broadly, I am confident ROCKWOOL will continue to lead the way in shaping the market and advancing the conversation around energy efficiency, energy security, and fire safety”.

Q2 2026 delivered strong 10 percent revenue growth in both local currencies and reported figures compared to last year with a record high revenue of 1,000 MEUR.
