Rock wool (or mineral wool) was discovered on the islands of Hawaii around the beginning of the nineteenth century. It occurs there naturally as a by-product of volcanic activity.

In its manufactured state, rock wool combines the power of rock with the characteristics of typical insulation wool. As a result of its non-directional fibre orientation, it also exhibits some unique and valuable characteristics.

Sound Absorbent

·         Unique non-directional structure of rock wool insulation is denser than traditional insulation products.

·         Non-directional fibres help to absorb acoustic waves and can reduce the intensity and propagation of noise.

·         Effectively reduces airflow and sound transmission.

·         Higher air flow resistivity means better sound attenuation.


Fire Resistant

·         Rock wool can withstand temperatures up to 1177º C, consequently, it does not contribute to the development and spread of fire or the release of toxic gases.


Water Repellent

·         Rock wool is water repellent yet vapour permeable.

·         The long-term R-value of stone wool is unaffected by moisture over time due to the inherent drying potential of the product.

·         Completely resistant to rot, mildew, mould and bacterial growth, contributing to a safer indoor environment.


Dimensional stability

·         Retains its characteristics over time.

·         Minimal changes in size and performance are evident with changes in temperature and humidity.
