Fireproof Rock Wool Board for Smoke Control

ABM® Fireproof Rock Wool Series designed for smoke prevention and exhausting systems. Its outstanding thermal stability and significant shrinkage resistance ability in high temperature can ensure the stable structure of smoke prevention and exhausting systems under the fire, providing an escape route for the trapped persons.

Smoke prevention and exhausting system includes smoke prevention system and smoke exhausting system, which are generally composed of exhaust ducts, pipe wells, fire valves, door switch equipment, air supply and exhaust fans and so on. In the event of a fire, the smoke prevention system uses a high-power positive pressure blower to prevent the smoke to enter the space of the smoke prevention system; the smoke exhausting system discharges the smoke from the building to protect trapped persons and save time for the safe evacuation.
