What is Mineral Wool Insulation?

Mineral Wool Insulation - Delmarva Insulation

Mineral wool, also called rock wool, is composed mainly of volcanic basalt rock and a recycled steel-making byproduct called slag. The rock and slag are superheated until liquefied and then mixed and stretched into thin pliable fibers. These fibers resemble wool and are compressed into a mat and then cut into batts. Mineral wool can also come as rolls or loose-fill insulation.


Mineral wool is one of the safest forms of insulation and has been described as “virtually incombustible.” In Europe, many extensive studies have been done over the last 50 years to verify its safety. Due to its composition, it is naturally highly flame retardant and does not require fire-retardant treatments used in other types of insulation. Mineral wool can reduce the spread of fire between rooms, helping your building to remain standing longer. This provides valuable extra minutes to save people and property and reduce environmental damage.


When produced, mineral wool creates very little waste, making it an environmentally friendly material. It helps conserve scarce resources and protect the environment by reducing the amount of fossil fuels consumed during its creation. It is frequently made from natural materials that can be recycled back into the manufacturing process.

Mineral wool is significantly less dense than some of its counterparts. This means that less energy is used in the manufacturing process, making it a very good option if you or your business are concerned with reducing your carbon footprint.

Thermal Performance

Mineral wool offers very good levels of thermal performance. It can be built to withstand temperatures of over 700 degrees. This makes it the ideal material for use in commercial insulation applications or any other environment that will be exposed to extreme heat.

Other Benefits

Mineral wool has many other benefits homeowners and builders can also take advantage of:

  • Soundproofing – The structure of mineral wool is porous and elastic, making it perfectly structured to absorb sound to help you enjoy a quieter living environment.
  • Moisture resistant – Its makeup makes it naturally moisture resistant, allowing it to retain its insulating qualities when wet while helping to prevent mold and mildew. This makes it a great option for insulating spaces that face moisture issues.
  • Improved indoor air quality.
  • Lower energy bills – It has excellent thermal efficiency which helps lower your energy bills.
