What is the temperature range of mineral wool?

Mineral wool, also known as rock wool or stone wool, is a type of insulation made from natural or synthetic minerals. Its notable characteristic is its ability to withstand high temperatures, making it a preferred choice for insulation in various industrial applications.

The correct answer reflects the exceptional temperature range of mineral wool, which can endure between -85°C to 650°C. This wide range allows mineral wool to maintain its structural integrity and insulating properties even in extreme conditions, making it suitable for applications like fire protection, soundproofing, and thermal insulation in facilities such as power plants or commercial buildings.

The other options do not accurately represent the capabilities of mineral wool. For example, the lower temperature limits of the other choices do not extend as low as its minimum tolerance, and their upper limits fall significantly short of the maximum temperature that mineral wool can endure. This characteristic is crucial for professionals in construction and insulation to understand, as it ensures their materials will perform effectively in the environments they are installed in.
