We are global leaders: Headquartered in Denmark, the ROCKWOOL Group is the largest producer of stone wool insulation and the second largest insulation manufacturer of any type in the world.

Our product is environmentally friendly: Our insulation is created from a natural, sustainable resource and is recyclable. We are proud of our environmentally responsible, high-tech production process. During its lifetime, a typical ROCKWOOL insulation product will save more than 100 times the energy used in its manufacture.

We actively strive to be a good neighbour: Our commitment to responsible business began in the 1950s, long before CSR became fashionable, and lies at the heart of our company values. Our donations programme enables us to contribute to local causes, whilst our staff team is active in organising charitable fundraising activities.
