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.

01

Fire resilience

Withstand temperatures above 1000°C.

In land-scarce urban areas, more and more people are working and making their homes in high-rise buildings. These structures can be brilliant solutions to the challenge of safely housing a growing population.

02

Thermal properties

Save energy by maintaining optimum indoor temperature and climate.

It makes living and working conditions more healthy and comfortable, helping people to thrive, especially in urban environments. Temperature maintenance can dramatically reduce heating, cooling, and ventilation costs, and reduce a building’s carbon footprint.

03

Acoustic capabilities

Block, absorb or enhance sounds.

From railways to tramways, roads to airports, good infrastructure is crucial to urban life, which can be very noisy. The resulting ground-borne vibration, traffic noise – and not to mention human noise pollution – all have a serious and negative impact on our wellbeing, especially in densely populated areas.

04

Robustness

Increased performance and greater stability with lower costs.

In land-scarce urban areas, more and more people are working and making their homes in high-rise buildings. These structures can be brilliant solutions to the challenge of safely housing a growing population.

05

Aesthetics

Match performance with aesthetics.

When people live and work in aesthetic spaces, they feel comfortable and motivated. Environments in which people enjoy spending time can improve social cohesion and make neighborhoods safer and healthier.

Water properties

Manage our most precious resource.

A growing population puts traditional food production under pressure, and climate change has increased the need for flood defenses. Stone wool can be engineered to absorb or repel water as needed, as well as recirculate it in a greenhouse, solving a range of water management problems.

07

Circularity

Reusable and recyclable materials.

Rock is one of the most abundant raw materials on the planet, but we still need to make better use of our planet’s resources. We have developed our technology in a way that allows us to use waste from other industries as alternative raw material.
