SRW FIRE BOARD

Fire Board is high density Rock Wool Board insulation, made from Rock Wool fibers, bonded with a special fire resistant binder. Fire board meets the technical requirement of ASTM C-612.

Application It is used in cases where fire insulation and fire rating are required, e.g., between wall top and the bottom of a concrete slab (gap seal), fire insulation of steel structure, air duct, fire proof doors, fire proof wall partitions in buildings and ships, etc. Different fire rating can be achieved depending on the board thickness and the structural element construction. Special Rock Wool fire stop board for electromechanical works (electric cables, ducts and pipes, wall or floor slab penetration) can be produced to provide the required fire rating.
Storage It must be stored in an area where it is protected against water and physical damage.
Maintenance Once Fire Boards are installed they do not need any maintenance.
Advantages
  • Highest fire rating.
