What is the maximum service temperature of mineral wool?

Explanation:
Mineral wool insulation is designed to handle very high heat, with a practical service limit around 1900°F (approximately 1038°C). This rating comes from its inorganic composition and high melting point, which let the fibers and structure stay stable in hot environments like furnaces and high-temperature ducts. Going beyond this temperature can cause the binder or fibers to degrade and reduce both insulation performance and structural integrity. The other temperatures are not representative of typical mineral wool limits: 1200°F is too low for many common applications, 2300°F is generally above what standard mineral wool products are rated for, and 1500°F is also below the usual maximum for many products.
