หมวดหมู่ : Bio Fireshield FOR LARGE OPENING


BIOSTOP® Composite Sheet is a rigid fire resistive panel used to seal penetrations and restore the fire rating to floor/ ceilings or walls in which a large opening has been made for the passage of penetrating items. It is made of a reinforced, highly intumescent material which is bonded on one side to a galvanized steel sheet. In addition to sealing penetrations through large openings, BIOSTOP® Composite Sheet is also used for shielding cable trays, conduit, and vital process equipment from radiant heat, flame spread and smoke.

The BIOSTOP® Composite Sheet functions as an effective intermediate fire-break within horizontal and vertical cable tray runs and is excellent for both new and retrofit construction. When exposed to a fire the material forms a refractory char that retards heat transmission and tightly seals penetrations against flame spread, smoke and toxic fumes. The nominal 0.2 inch (5 mm) thick composite sheet provides up to a 3 hour fire rating. It is lightweight and can be easily installed with common trade tools.

  • Intumesces (expands with heat) to form a refractory char that tightly seals penetrations against flame spread, smoke and toxic fumes.
  • Easy to install using common trade tools.
  • Lightweight ... easy to handle, cut and form to desired shape.
  • Easy to fasten... bolt punch or drill through. Use self-tapping screws or anchor bolts.
  • Thermally conductive: allows unwanted heat build-up to escape.
  • Non-flame supporting.
  • UL Classified.
  • Cost effective, high performance versus installed cost.
  • No mixing or damming... is clean to install.
  • Versatile: can be cut to fit irregular shapes.
  • Re-enterable.
