Rock mineral wool is made mainly from volcanic rock, typically basalt and/or dolomite. An increasing proportion is now recycled material from slag, a waste product from blast furnaces and form the rock wool insulation. The materials are melted and then spun fibersine fibres. A resin is used to bind the fibres together to form a mat of insulation.
- Short fibre- compressive strength.

- Denser than glass mineral wool.
- Available in the form of slabs, rolls mattresses and pipe sections.
- High compressive strength.
- Thermal insulation of flat roofs and external wall insulation.
- Fire protection, including smoke and fire barriers.
- High temperature applications.
- Sound insulation for floors and walls.
- Thermal and acoustic insulation of pipe work in heating and ventilation, air-conditioning and industrial applications.
- Blanket Insulation
- Board / Slab Insulation
