Discontinuous-line mineral wool

Panels for walls and roofs

Mineral wool, also known as rock wool, is a natural product created by means of fusion and solidification processes involving rock, sand and glass. The life cycle of this product is among the most biocompatible and fulfils all the “green” requirements which businesses are increasingly compelled to satisfy to safeguard the environment and human health.

Mineral wool is used to produce sandwich panels for civil and industrial buildings, where they are used as walls or roofing to isolate rooms from the cold, heat and noise. Moreover, they offer excellent fire-reaction and fire-resistance properties.

A few characteristics of mineral wool


Thanks to its fire-retardant properties, mineral wool prevents excessive heat from damaging the internal structure of the mineral fibre. It protects against fire and helps to slow down the propagation of a fire.

Sound-proofing, sound-absorbing

The open-cell structure of mineral wool favours the absorption of sound waves and allows for damping the intensity and propagation of noise.

Stability in humidity

Thanks to its special structure, mineral wool does not absorb humidity (it is not hygroscopic), therefore it retains its characteristics unaltered over time.

Bacteriological and non-toxic properties

Mineral wool is chemically neutral. It does not contain any aggressive or corrosive products and, being non-toxic, does not aid the growth of micro-organisms. The largely inorganic nature of mineral wool products is a guarantee of safety – in case of fire – with regard to fume and toxic gas emissions.

Stability over time and resistance to ageing

Mineral wool remains stable over time, withstands ageing and is able to ensure lasting performances.


Mineral wool is a biosoluble material and is absolutely harmless to man and the environment. It is not carcinogenic and is safe to manipulate and use, provided that suitable precautions are taken.
