Thermafiber FireSpan™ products are designed to provide life saving fire protection in curtain wall and perimeter fire containment systems. These products are noncombustible, moisture-resistant, noncorrosive, nondeteriorating, mildew-proof and vermin-proof. FireSpan 40 & 90 provide thermal insulation, fire protection, acoustical and vapor control in many different fire containment assemblies of 1, 2, and 3-hr ratings.
- Standard Fiber = 70% Post-Industrial Recycled Content
- EPA Choice Fiber (For US Government Projects) = 75% Post-Industrial Recycled Content
- Meets the EPA Comprehensive Procurement Guidelines for Rock Wool insulation
- Dark Fiber (for aesthetics) = 84% Post-Industrial Recycled Content
- Green Fiber = 90% Post-Industrial Recycled Content
- FireSpan 40, 2" or greater thickness, is available with a vapor retarding foil facing.
- FireSpan 90, 1" or greater thickness, is available with a vapor retarding foil facing.
- Both FireSpan 40 and 90 are available in dark and regular colored fibers for aesthetic purposes.
FireSpan products should be mechanically attached to horizontal and vertical mullions with architect approved insulation fasteners. Reinforce FireSpan on the outer insulation surface at the safing line. Typical reinforcement members include hat channels, "L" angles, and "T" bars. Thermafiber's patented Impasse® system is designed to quickly and easily mechanically attach FireSpan insulation to curtain wall systems.
