SAFB (Sound Attenuation Fire Blankets)

SAFB (Sound Attenuation Fire Blankets)

Thermafiber® SAFB (Sound Attenuation Fire Blankets)

Description:

THERMAFIBER Sound Attenuation Fire Blankets (SAFB) are mineral wool batts designed to stop sound, save energy, and provide life saving fire protection. These products are noncombustible, moisture-resistant, noncorrosive, nondeteriorating, mildew-proof and verminproof. Thermafiber SAFBs provide acoustical control, thermal insulation, and fire protection in many different UL fire rated wall and floor-ceiling assemblies. SAFBs resist temperatures over 2000ºF as compared to fiberglass insulation that melts around 1000ºF. SAFBs add STCs to wall and floor-ceiling assemblies. SAFBs can be installed in both steel stud and wood stud construction. See Thermafiber’s SAFB Brochure (TF885) for more detail on STC and fire ratings for multiple wall and floor-ceiling assemblies.
