Mineral Wool Insulation

Definition - What does Mineral Wool Insulation mean?

Mineral wool insulation is an insulator that is frequently used in the construction industry and piping industry. Mineral wool insulation is a poor thermal conductor, and it has excellent flame resistant properties. Mineral wool insulation is also used as an acoustic dampener.

Mineral wool insulation may also be known as rock wool insulation, stone wool insulation, or slag wool insulation.

Corrosionpedia explains Mineral Wool Insulation

Mineral wool insulation is made from a mixture of stone and slag, which is why it is also called rock wool insulation, stone wool insulation or slag wool insulation. The stone or slag is heated in a furnace until it becomes molten. Then, in a process similar to manufacturing cotton candy, the molten rock or slag is spun until it cools in the formation of long, thin fibers. The fibers are then densely packed on top of each other.

Mineral wool insulation is used in buildings and structures for several reasons. First and foremost, mineral wool insulation does not conduct heat well. This is important when trying to keep a building warmer or cooler than the outside environment. Since fires are always a concern for buildings, the fact that mineral wool lacks flammability makes it an excellent option as an insulator. Also, mineral wool is an excellent acoustic dampener if noise is a concern when building a structure.

Mineral wool insulation is common in the piping industry for similar reasons. Its resistance to flame and deformation due to heat make it a great option for pipes that transport high-temperature materials. Since it is a thermal insulator, it can also prevent pipes from freezing in cold weather applications.
