THERMAFIBER® SAFING
WHY CHOOSE MINERAL WOOL INSULATION?
Thermafiber® Safing mineral wool insulation products are designed to provide fire protection in perimeter fire containment systems, floor and wall penetrations, construction joints, and other firestopping applications.
Description
Thermafiber® introduces the first formaldehyde free, GreenGuard® Gold certified perimeter fire containment mineral wool insulation in North America. Safing mineral wool insulation products are designed to provide enhanced fire protection in perimeter fire containment systems, floor and wall penetrations, construction joints, and other fire stopping applications. Thermafiber® Safing meets green building standards by using products that exclude red list materials like formaldehyde. These products are non- combustible, moisture-resistant, non-corrosive, non-deteriorating, mildew resistant, and vermin-resistant.1 Thermafiber® Safing provides thermal insulation, fire containment, and enchanced acoustical performance in many different UL and Intertek (formly OPL) listed fire containment assemblies of 1, 2, and 3-hr ratings. The new formaldehyde free Safing product is especially appropriate for applications in education, healthcare, and other institutions committed to indoor air quality.

Perimeter Fire Containment Tests Per ASTM E 2307
Safing insulation is a critical component of any perimeter fire containment system. Thermafiber, Inc. has performed decades of testing in all of the containment systems listed below.
- Back pan curtain wall fire containment
- Steel Stud-Framed/Gypsum Sheathing Curtain Wall Fire Containment
- Glass Spandrel Curtain Wall Fire Containment
- Granite Spandrel Curtain Wall Fire Containment
- Precast Concrete Spandrel
- Steel Back Pan Curtain Wall Fire Containment
For additional job specific details and accessory materials necessary to complete the Perimeter Fire Containment System, please refer to UL® design listing. Underwriters Laboratories (UL) Designs, Fire Resistance Directory, UL. 333 Pfingsten Road, Northbrook, IL 60062.
See Owens Corning publication “Enclosure Solutions Perimeter Fire Containment System E2307 Curtain Wall Technical Bulletin” (Pub. No. 10020920) for more information.
Installation
All firestopping insulation should be installed per the architectural specification or system specific test description. All compressed Safing insulation should be installed per the listed assembly.
- Perimeter Installation: Safing insulation should be compression fitted between the slab edge and the FireSpan® curtain wall insulation, leaving no
- Penetration Application: Safing insulation should be cut slightly larger than the opening and compression fitted into the opening, leaving no
- Construction Joint Application: Safing insulation should be compression fitted into the joint opening, leaving no
