Mineral wool is a stone-based mineral fiber insulation comprised of Basalt rock and recycled steel slag. It costs about about 25% to 45% more than fiberglass, but I feel its benefits more than justify the additional costs.
Historically, common practice was to use calcium silicate for applications with operating temperatures between 200 ÂºC and 650 ÂºC; however mineral wool can be used in the range 90 ÂºC to 425 ÂºC and has slightly better thermal resistance than calcium silicate at lower temperature ranges, and is typically less costly.lexural and compressive strength is good. Calcium silicate is water absorbent; however it can be dried out without deterioration. The material is non-combustible and used primarily on hot piping and surfaces. Jacketing is field applied.
