Thermafiber SAFB FF batts provide excellent acoustical control and fire protection in interior walls and floor/ceiling fire-rated assemblies and are non-combustible, moisture-resistant, non-corrosive, non-deteriorating, and mold-resistant. The new formaldehyde-free Thermafiber light density products are especially appropriate for applications in education, healthcare, and other institutions committed to indoor air quality. SAFB FF can be installed in both steel and wood framed construction. (Footnotes: 1. Reference Cradle to Cradle Innovation Instituion banned list and Living Building Challenge red list 2. ASTM C1338)
