We transform volcanic rock into stone wool and our products contribute to address many of society’s biggest climate change challenges, creating new opportunities to enrich modern living and build safer, healthier, and more climate resilient communities.
Indeed, stone wool is a versatile natural material with multiple benefits that makes it ideal for applications in buildings, industry, transportation, horticulture, and water management.
Stone wool is non-combustible, with built-in fire protection that is not dependent on chemical flame retardants. Stone wool withstands temperatures exceeding 1000 degrees Celsius, it’s durable, and retains its fire performance during its working life.
ROCKWOOL’s technical and building insulation products achieve the top fire performance Euroclass Reaction to Fire Classification, either A1or A2-s1, d0.
ROCKWOOL is durable and does not change over time. Meaning our materials last throughout generations without loss of performance, while retaining its fire, thermal and acoustics properties – helping ensure continued energy savings and comfort over decades.
ROCKWOOL building insulation sold in 2025 is expected to save almost 100 times the energy used to produce it.
ROCKWOOL building insulation sold in 2025 is expected to save 495 TWh of energy over its lifetime – close to the equivalent to the 2025 electricity consumption of France, population of 68M.

Our ROCKWOOL Rainwater system can retain up to 95 percent of water and filter run-off, removing 80 percent of solids and 50 percent of chemicals. Contributing to building smart cities – one drop at a time.
We estimate that in 2025, our Rockfon acoustic solutions improved educational environments for thousands of students worldwide.
ROCKWOOL's Rainwater Management systems helps tackle two critical megatrends head-on:
Manage stormwater smarter with a proven ROCKWOOL solution
In 2025, ROCKWOOL Rainwater Systems completed 500 projects, representing a water-buffering capacity of 85,000,000 litres, equivalent to 36 Olympic swimming pools.
Grodan offers innovative stone wool growing media solutions for the professional horticulture sector based on Precision Growing principles. Meaning plants are provided with exactly what they need – nothing more and nothing less. This way of farming allows increased efficiency while better managing some of our most precious resources we have: water and land.
Farmers using Controlled Environment Agriculture (CEA) can increase yields while using less water, land and fertiliser. What’smore, with Grodan, they have the possibility to reduce or even eliminate chemical plant protection products.
ROCKWOOL has a critical role to play in the renovation wave and we are ready to act.
Discover how our Group Sustainability Statement provides a holistic view of how ROCKWOOL's products can support communities and increase our positive impact through new initiatives while reducing our negative environmental impact.

The Wageningen University & Research
In 2017, ROCKWOOL partnered with the Wageningen University & Research, specialising in life science, to develop a methodology on a quantitative comparison between soil based cultivation systems and stone wool systems.
One Ocean Foundation
In 2022, ROCKWOOL has joined forces with One Ocean Foundation in a multi-year global scientific partnership focused on accelerating solutions to protect and regenerate our ocean.
ROCKWOOL Denmark SailGP team collaborates with One Ocean Foundation with the objective to analyse, track and reduce the carbon and plastic footprint of team operations as part of SailGP’s Impact League initiative.
Circular Economy
Supported by Circle Economy Consulting, ROCKWOOL has developed a set of circularity KPIs to not only support disclosure in relation to CSRD and the EU Taxonomy, but also to help drive the transition along every step of the value chain. Circle Economy Consulting has developed an indicator dashboard for ROCKWOOL to measure its efforts against applying to different steps of the value chain: Circular materials, Circular use and Circular end-of-life.
