FireSpan Curtain Wall Insulation

Description:

THERMAFIBER FireSpan products are designed to provide life saving fi re protection in curtain wall and perimeter fi re containment systems. These products are noncombustible, moisture-resistant, noncorrosive, nondeteriorating, mildewproof and vermin-proof. FireSpan 40 & 90 provide thermal insulation, fi re protection, acoustical and vapor control in many different fi re containment assemblies of 1, 2, and 3-hr ratings.

Product Options:
  • 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 fi bers for aesthetic purposes.
  • Recycled Content Options1:

      • Special “Green” Fiber ............................................ 90%
      Dark Fiber ............................................................. 84%
      EPA Choice Fiber (US Government Buildings) ........ 75%
      Standard Fiber ...................................................... 70%
      1Recycled content options other than standard must be specifi ed at time of order.

    Installation:

    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 safi ng line. Typical reinforcement members include hat channels, “L” angles, and “T” bars. Thermafi ber’s patented Impasse system is designed to quickly and easily mechanically attach FireSpan insulation to curtain wall systems.
