Thermafiber® SAFB™ | Owens Corning Insulation Skip to Main Content

Thermafiber® SAFB™ (Sound Attenuation Fire Blankets) are mineral wool batts designed to provide acoustical control and fire protection in many UL® fire-rated wall and floor-ceiling assemblies. These products are non-combustible, moisture resistant, non-corrosive, non-deteriorating, mildew-resistant, and vermin-resistant. SAFB™ resists temperatures over 1,093ºC (2,000ºF) and can add points to STC for walls and floor-ceiling assemblies. SAFB™ can be installed in both steel stud and wood-framed construction.

Features

  • Exceptional sound and noise absorption
  • Adds STC value to wall and floor-ceiling assemblies
  • Provides fire containment in rated assemblies
  • Fire-resistant to temperatures above 1,093ºC (2,000ºF)
  • See UL file R4739 for fire rated assembly listings
  • Minimum 70% recycled content
  • Mold-resistant1
  • Contributes to credits in several green building programs, such as LEED® and Green Globes®

Standards, Codes Compliance

  • CAN/ULC-S702.1, Standard for Mineral Fiber Thermal Insulation for Buildings2
  • NFPA 101, Class A-rated interior finish
  • Fire Rated Design
    - ULC Classification Code: BZJZC
    - UL Classification Code: BZJZ

Installation

  • Interior Stud Cavity – Friction-fit SAFB™ securely between studs. Butt ends of blankets closely together and fill all voids.
  • Creased SAFB™ – Using SAFB™ 25 mm (1") wider than regular blankets, bow the blankets slightly to fit into stud cavity. Slit the blankets vertically 25 mm (1") deep with a utility knife down the center.
  • Floor-Ceiling – Friction-fit SAFB™ securely between floor joints.
  • Ceiling Overlayment – Lay SAFB™ over ceiling panels, extending 1219 mm (48") beyond all partitions. Tightly fit around all hangers, obstructions, and penetrations.
1 Tested per ASTM C1338, Standard Test Method for Determining Fungi Resistance of Insulation Materials and Facings, ASTM International.
2 Complies to all physical properties in CAN/ULC-S702.1 with the exception of thermal resistance and resistivity which is not measured.

Certifications and Sustainable Features

  • Verified by ICC-ES to contain a minimum of 70% recycled content. See ICC-ES Evaluation Report VAR-1025 at icc-es.org.
  • Environmental Product Declaration (EPD) has been certified by UL Environment. For more information, visit ul.com/epd.
  • SAFB™ products have a published Health Product Declaration (HPD).
