Mineral Wool

Mineral Wool

Mineral Wool (Slag/Rock Wool) manufactured from molten industrial slag, which is fiberized, treated with oil and binders to suppress dust, and maintain shape.  It is similar to glass fibre in texture and appearance but denser than glass-wool so R-Value per unit thickness is higher.  Rock Wool is manufactured in a similar manner except that natural rock is used instead of slag.  These materials have a high fire resistance, limiting operating temperature 850°C. Generally rock wool is more expensive than glasswool. It can cause eye, skin and respiratory irritation during installation.
