Mineral wool is a catch-all term that can be used to describe two different forms of material:

• Glass mineral wool
• Rock mineral wool.

Both rock mineral wool and glass mineral wool can be produced in a variety of densities, making both options versatile and suitable for a wide range of building applications including Heat Insulation, Acoustic Insulation and Thermal Insulation

Whilst inherently similar, the two materials are different.

Rock mineral wool is a dense material, offering tremendous thermal and acoustic properties. As a dense material, rock mineral wool provides exceptional protection against excess noise and as such, can be used to insulate properties against sound just as effectively.

Solutions manufactured from glass mineral wool offer solid thermal and acoustic properties but are outperformed by rock mineral wool alternatives. Likewise, as a less dense material, glass mineral wool also offers inferior performance in terms of sound insulation.
