Mineral wool insulation is a multifaceted material known for its excellent thermal insulation, sound absorption, and fire resistance. It is widely used in construction for fireproofing and in industrial settings for high-temperature insulation, such as in furnaces. Mineral wool also plays a crucial role in hydroponic agriculture, where it supports plant growth by maintaining proper water and air levels. Health and environmental considerations are addressed with modern fibers that are less persistent in the body and considered noncarcinogenic.

Mineral wool is compressed into rolls or batts to trap air and reduce heat transfer, making it an effective thermal insulator and sound absorber
Due to its inherent fire resistance, mineral wool is commonly used in construction for fireproofing in wall cavities, ceilings, and firestop systems
Mineral wool has a wide range of uses beyond construction, including in the manufacture of various products such as resin-bonded panels, gaskets, and automotive components, as well as in hydroponic agriculture
Mineral wool's thermal endurance is classified by type, with glass wool able to withstand temperatures up to 230-260°C, stone wool up to 700-850°C, and ceramic fiber wool up to 1200°C
Mineral wool is engineered to retain water and air for optimal plant growth in hydroponic systems, but its high pH requires conditioning for plant tolerance
Mineral wool's ability to withstand high temperatures makes it essential for thermal insulation in industrial settings, such as furnaces and foundries, improving energy efficiency and safety
While some types of mineral wool, such as refractory ceramic fibers and certain glass wools, are classified as possibly carcinogenic, others, including insulation glass wool, stone wool, and slag wool, are not considered carcinogenic
Newer bio-soluble fibers are less persistent in the body and generally considered noncarcinogenic, and in the European Union, mineral wool fibers meeting specific criteria are not classified as hazardous
Regulatory agencies have established guidelines and exposure limits for the production and use of mineral wool to minimize health risks and environmental impact, and manufacturers provide guidelines for safe handling and exposure minimization
