Mineral-wool insulation

Thermafiber FireSpan mineral-wool insulation is said to provide enhanced fire containment in rated assemblies. Naturally non-combustible and fire resistant to temperatures above 2,000 F, the material provides fire containment, thermal insulation, acoustical performance, and vapor control in many UL- and Intertek-listed fire-containment assemblies.
