Stone and civilisation were made for each other. ROCKWOOL makes the most of this relationship to improve our health, well being and comfort.
Stone wool (or mineral wool) was discovered on the islands of Hawaii around the beginning of the nineteenth century and occurs as a natural byproduct of volcanic activity. There is something uniquely exciting about turning an abundant natural resource into products that enrich modern life.
In its manufactured state, stone wool delivers unique benefits as an insulation solution. In part due to its non-directional fiber orientation, stone wool also exhibits unique benefits which have come to be known as the 7 strengths of stone.
Fire Resistant for occupant safety: ROCKWOOL stone wool can withstand temperatures greater than 1,800°F (1,000°C) and does not contribute to the development and spread of fire or the release of toxic gases.
Sound Absorbent for acoustic comfort: The non-directional structure of ROCKWOOL stone wool insulation is denser than traditional insulation products which helps to absorb acoustic waves and can reduce the intensity and propagation of noise. Stone wool also effectively reduces airflow and sound transmission, while providing higher airflow resistivity for improved sound attenuation.
Water Repellent to keep you dry: ROCKWOOL stone wool is water repellent yet vapor permeable meaning that the long-term R-value is unaffected by moisture over time. This is due to the inherent drying potential of the product which is also resistant to rot, mold and mildew growth—contributing to a safer indoor environment.
Dimensional stability means maintaining performance: Stone wool retains its characteristics over time which means reducing maintenance over the life of the home or building. Even with changes in temperature and/or humidity over long periods of time, there are minimal changes in the size or performance of our solutions.
We have been able to break down the natural power of stone into 7 strengths that are inherent in the versatile properties of stone wool. These are seven reasons why we believe the world’s most abundant resource can be engineered to create uniquely useful and exciting solutions for our customers.
By applying these 7 strengths to everything we do, we passionately believe that we can address some of the biggest challenges facing our world. We’re sure that there are even more strengths of stone to be discovered, and when we discover them, we’ll turn those strengths into new products that improve the quality of life of everyone who comes into contact with them. That’s why these 7 strengths lie at the heart of every ROCKWOOL product.
Our products are diverse and contribute to shaping a circular economy, enhancing resource efficiency, and nurturing the safety, health and wellbeing of people.
