DESCRIPTION: Precured dry intumescent sheet bonded to thin, rigid steel panel, for cutting and forming to custom or irregular shapes. Used for sealing penetrations and/or restoring fire rating to floors, walls and ceilings with penetrating openings.

  • Easy to install using common trade tools; fasten, bolt punch or drill through using self-tapping screws or anchor bolts; no mixing or damming for clean install; cost-effective low labor install; is re-enterable
  • Non-flame supporting and thermally conductive: allows unwanted heat build-up to escape.
  • FBC System compatible
