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 fi re protection. These products are noncombustible, moisture-resistant, noncorrosive, nondeteriorating, mildew-proof and verminproof. Thermafi ber SAFBs provide acoustical control, thermal insulation, and fi re protection in many different UL fi re rated wall and fl oorceiling assemblies. SAFBs resist temperatures over 2000ºF as compared to fi berglass insulation that melts around 1000ºF. SAFBs add STCs to wall and fl oor-ceiling assemblies. SAFBs can be installed in both steel stud and wood stud construction. See Thermafi ber’s SAFB Brochure (TF885) for more detail on STC and fi re ratings for multiple wall and fl oor-ceiling assemblies.

1Recycled content options other than Standard must be specifi ed at time of order. - Standard SAFB
- Creased SAFB – Made 1” wider than standard stud spacing to bow in the stud cavity for increased sound absorption.
Installation:- Interior Stud Cavity – Friction fi t SAFBs securely between studs. Butt ends of blankets closely together and fi ll all voids.
- Creased SAFB – Bow the blankets slightly to fi t into stud cavity. Slit the blankets vertically 1” deep with a utility knife.
- Floor-Ceiling – Friction fi t SAFBs securely between fl oor joists.
- Ceiling Overlayment – Lay SAFBs over ceiling panels extending 48” beyond all partitions. Tightly fi t around all hangers,
obstructions, and penetrations.
