Mineral Wool insulation blankets are multi-layer coverings engineered to contain heat and maintain a touch-safe surface temperature. A protective outer layer shields against moisture or tears while an internal insulation layer traps heat within the wrapped system. These coverings may be applied to engine parts, exhaust systems, process piping, and other machinery that reaches high temperatures.

The use of rigid panel mineral wool, also known as rockwool, is recommended for soundproofing a room. They can also be purchased in softer batts as opposed to rigid panels. Rockwool is sold in sizes for use with ceilings, floors, and residential interior walls
